METHODS: Fifty hepatocellular carcinoma (HCC) patients with portal vein tumor thrombosis (PVTT) were treated using hepatic arterial infusion chemotherapy (HAIC) via a subcutaneously implanted port. The epirubicin-cisplatin-5-fluorouracil (ECF) chemotherapeutic regimen consisted of 35 mg/m 2 epirubicin on day 1, 60 mg/m 2 cisplatin for 2 h on day 2, and 500 mg/m 2 5-fluorouracil for 5 h on days 1-3. The treatments were repeated every 3 or 4 wk. RESULTS: Three (6%) of the 50 patients achieved a complete response (CR), 13 (26%) showed partial responses (PR), and 22 (44%) had stable disease (SD).The median survival and time to progression were 7 and 2 mo, respectively. After 2 cycles of HAIC, CR was achieved in 1 patient (2%), PR in 10 patients (20%) and SD in 26 patients (52%). Significant pre-treatment prognostic factors were a tumor volume of < 400 cm 3 (P = 0.01) and normal levels of protein induced by vitamin K absence or antagonist (PIVKA)-Ⅱ (P = 0.022). After 2 cycles of treatment, disease control (CR + PR + SD) (P = 0.001), PVTT response (P = 0.003) and α-fetoprotein reduction of over 50% (P = 0.02) were independent factors for survival. Objective response (CR + PR), disease control, PVTT response, and combination therapy during the HAIC were also significant prognostic factors. Adverse events were tolerable and successfully managed. CONCLUSION: HAIC may be an effective treatment modality for advanced HCC with PVTT in patients with tumors < 400 cm 3 and good prognostic factors.展开更多

The demographics, laboratory analyses, and histopathology data were analyzed.RESULTS Overall survival(OS) and disease-free survival(DFS) were determined in the patients with a high(> 2.9) and low(≤ 2.9) NLR. The median OS and DFS duration in the high NLR group were significantly shorter than those in the low NLR group(OS: 6.2 mo vs 15.7 mo, respectively, P = 0.007; DFS: 2.2 mo vs 3.7 mo, respectively, P = 0.039). An NLR > 2.9 was identified as an independent predictor of a poor prognosis of OS(P = 0.034, HR = 1.866; 95%CI: 1.048-3.322) in uni-and multivariate analyses. Moreover, there was a significantly positive correlation between the NLR and the Child-Pugh score(r = 0.276, P = 0.015) and the maximum diameter of the tumor(r = 0.435, P < 0.001). Additionally, the NLR could enhance the prognostic predictive power of the CLIP score for DFS in these patients. CONCLUSION The preoperative NLR is a prognostic predictor after hepatectomy for HCC patients with PVTT/HVTT. NLR > 2.9 indicates poorer OS and DFS.展开更多

In addition, cost-effective treatments are highly desirable when chemotherapy must be given repeatedly. The aim of this study was to evaluate the efficacy and usefulness of 5-fluorouracil (5-FU) and high-concentration cisplatin by short-term hepatic arterial infusion chemotherapy (3-day FPL) in advanced HCC patients. Methods: Thirty patients with unresectable advanced HCC were enrolled. The patients underwent hepatic arterial infusion chemotherapy via the implanted port system with 5-FU on days 1 - 3 and a fine-powder formulation of cisplatin in suspended pre-warmed lipiodol on day 2 every 4 to 10 weeks. Tumor response was assessed one month later with CT. Results: All patients had evidence of portal vein invasion (Vp2-4). Four patients achieved a complete response (CR), 8 patients achieved a partial response (PR), and 7 patients had stable disease (SD). The median progression-free survival (PFS) and overall survival (OS) were 198 days and 452 days, respectively. The OS was significantly longer in the successful disease control group (CR, PR, and SD) than in the progressive disease group (P < 0.005). Conclusions: Three-day FPL was effective and tolerable in advanced HCC patients due to its shorter time of administration than conventional FP therapy. Therefore, repetitive 3-day FPL appears useful and contributes to improving the prognosis and QOL of patients with advanced HCC. In addition, this protocol is a cost-effective treatment.展开更多

Therefore, an effective treatment regime is needed for treating HCC with PVTT. This review summarized seven potential treatment regimes which including transarterial chemoembolization (TACE), TACE combined with sorafenib, TACE combined with radiotherapy (RT), hepatectomy, hepatic arterial infusion chemotherapy (HAIC), HAIC combined with sorafenib and HAIC combined with RT in the treatment of HCC with PVTT. In conclusion, hepatectomy or the combination of HAIC and sorafenib may be a more effective modality in the treatment of HCC patients with type I - II PVTT. HAIC combined with or without sorafenib/RT or the combination of RT and TACE is an alternative treatment choice for HCC patients with type III - IV PVTT. Further randomized controlled studies are warranted.展开更多

An increasing pool of evidence exists supporting the use of pegylated-interferon (pegIFN) and ribavirin combination therapy for hepatitis C. We report a 49-year old male of North American aboriginal descent with chronic hepatitis C (genotype 2b). Biopsy confirmed that he had cirrhosis with a 2-wk history of left eye pain and decreased visual acuity. He developed retinal vein thrombosis after 16 of 24 wk of pegIFN-α 2a and ribavirin combination therapy. He was urgently referred to a retinal specialist and diagnosed with non-ischemic central retinal vein occlusion of the left eye. PegIFN and ribavirin combination therapy was discontinued and HCV RNA was undetectable after 16 wk of treatment. Hematologic investigations revealed that the patient was a factor V Leiden heterozygote with mildly decreased protein C activity. Our patient had a number of hypercoagulable risk factors, including factor V Leiden heterozygosity, cirrhosis, and hepatitis C that alone would have most likely remained clinically silent. We speculate that in the setting of pegIFN treatment, these risk factors may coalesce and cause the retinal vein thrombosis.展开更多

In this paper, we report 2 cases of postoperative hepatic vein thrombosis after liver resection. Both patients had undergone major hepatectomy of a non-cirrhotic liver largely exposing the middle hepatic vein. Clots were incidentally found in the middle hepatic vein 4 and 17 d after surgery despite routine systemic thrombo-prophylaxis with low molecular weight heparin. Coagulation of the transition plan in a context of mutation of the prothrombin gene and inflammation induced biloma were the likely predisposing conditions. Clots disappeared following curative anticoagulation. We conclude that thrombosis of hepatic veins may occur after liver resection and is a potential source of pulmonary embolism.展开更多

The search was supplemented by manually reviewing the references of included studies and the references of the main published systematic reviews on thrombosis and PLT. We excluded from this review case report, small case series, commentaries, conference abstracts, papers which describing less than 10 pediatric liver transplants/year and articles published before 1990. Two reviewers performed study selection independently, with disagreements solved through discussion and by the opinion of a third reviewer when necessary.RESULTS Nine retrospective studies were included in this review. The overall quality of studies was poor. A pooled analysis of results from studies was not possible due to the retrospective design and heterogeneity of included studies. We found an incidence of portal vein thrombosis(PVT) ranging from 2% to 10% in pediatric living donorliver transplantation(LDLT) and from 4% to 33% in pediatric deceased donor liver transplantation(DDLT). Hepatic artery thrombosis(HAT) was observed mostly in mixed LDLT and DDLT pediatric population with an incidence ranging from 0% to 29%. In most of the studies Doppler ultrasonography was used as a first line diagnostic screening for thrombosis. Four different surgical techniques for portal vein anastomosis were reported with similar efficacy in terms of PVT reduction. Reduced size liver transplant was associated with a low risk of both PVT(incidence 4%) and HAT(incidence 0%, P < 0.05). Similarly, aortic arterial anastomosis without graft interposition and microsurgical hepatic arterial reconstruction were associated with a significant reduced HAT incidence(6% and 0%, respectively). According to our inclusion and exclusion criteria, we did not find eligible studies that evaluated pharmacological prevention of thrombosis. CONCLUSION Poor quality retrospective studies show the use of tailored surgical strategies might be useful to reduce HAT and PVT after PLT; prospective studies are urgently needed.展开更多

The present study was to describe our surgical techniques of extended central hepatectomy.METHODS: Between 2008 and 2012, 5 patients with centrally located hepatocellular carcinoma invading or in the vicinity of the right and middle hepatic veins underwent extended central hepatectomy. The thick inferior right hepatic vein was preserved during dissection. Gore-Tex graft was used for segment 6 outflow reconstruction in the absence of the thick inferior right hepatic vein.RESULTS: The mean future remnant liver volume for segments 2 and 3 was 28% versus 45% on segment 6 preservation. The mean tumor diameter was 7.4 cm. The thick inferior right hepatic vein was found in 1 patient. Outflow reconstruction from segment 6 was performed in 4 patients. Postoperative complications included bile leakage (1 patient), pleural effusion (2) and liver failure (1). The rate of graft patency was 75%. There was no perioperative mortality.CONCLUSION: Extended central hepatectomy is a safe alternative for extended hepatic resection in selected patients attempting to preserve the functional liver parenchyma.展开更多

文摘AIM: To evaluate the prognostic factors and efficacy of hepatic arterial infusion chemotherapy in hepatocellular carcinoma with portal vein tumor thrombosis. METHODS: Fifty hepatocellular carcinoma (HCC) patients with portal vein tumor thrombosis (PVTT) were treated using hepatic arterial infusion chemotherapy (HAIC) via a subcutaneously implanted port. The epirubicin-cisplatin-5-fluorouracil (ECF) chemotherapeutic regimen consisted of 35 mg/m 2 epirubicin on day 1, 60 mg/m 2 cisplatin for 2 h on day 2, and 500 mg/m 2 5-fluorouracil for 5 h on days 1-3. The treatments were repeated every 3 or 4 wk. RESULTS: Three (6%) of the 50 patients achieved a complete response (CR), 13 (26%) showed partial responses (PR), and 22 (44%) had stable disease (SD).The median survival and time to progression were 7 and 2 mo, respectively. After 2 cycles of HAIC, CR was achieved in 1 patient (2%), PR in 10 patients (20%) and SD in 26 patients (52%). Significant pre-treatment prognostic factors were a tumor volume of < 400 cm 3 (P = 0.01) and normal levels of protein induced by vitamin K absence or antagonist (PIVKA)-Ⅱ (P = 0.022). After 2 cycles of treatment, disease control (CR + PR + SD) (P = 0.001), PVTT response (P = 0.003) and α-fetoprotein reduction of over 50% (P = 0.02) were independent factors for survival. Objective response (CR + PR), disease control, PVTT response, and combination therapy during the HAIC were also significant prognostic factors. Adverse events were tolerable and successfully managed. CONCLUSION: HAIC may be an effective treatment modality for advanced HCC with PVTT in patients with tumors < 400 cm 3 and good prognostic factors.
文摘Hepatic encephalopathy(HE)is a cognitive disturbance characterized by neuropsychiatric alterations.It occurs in acute and chronic hepatic disease and also in patients with portosystemic shunts.The presence of these portosystemic shunts allows the passage of nitrogenous substances from the intestines through systemic veins without liver depuration.Therefore,the embolization of these shunts has been performed tocontrol HE manifestations,but the presence of portal vein thrombosis is considered a contraindication.In this presentation we show a cirrhotic patient with severe HE and portal vein thrombosis who was submitted to embolization of a large portosystemic shunt.Case report:a 57 years-old cirrhotic patient who had been hospitalized many times for persistent HE and hepatic coma,even without precipitant factors.She had a wide portosystemic shunt and also portal vein thrombosis.The abdominal angiography confirmed the splenorenal shunt and showed other shunts.The larger shunt was embolized through placement of microcoils,and the patient had no recurrence of overt HE.There was a little increase of esophageal and gastric varices,but no endoscopic treatment was needed.Since portosystemic shunts are frequent causes of recurrent HE in cirrhotic patients,portal vein thrombosis should be considered a relative contraindication to perform a shunt embolization.However,in particular cases with many shunts and severe HE,we found that one of these shunts can be safely embolized and this procedure can be sufficient to obtain a good HE recovery.In conclusion,we reported a case of persistent HE due to a wide portosystemic shunt associated with portal vein thrombosis.As the patient had other shunts,she was successfully treated by embolization of the larger shunt.

文摘Background:Studies about treatment of patients with chronic portal vein thrombosis(CPVT)are still limited,especially in different types of CPVT.This study aimed to evaluate the effect of transjugular intrahepatic portosystemic shunt(TIPS)in all types of CPVT with variceal bleeding.Methods:Patients with CPVT who received TIPS treatment between January 2011 and June 2019 were divided into four types according to the extent of thrombosis.All patients had a history of variceal bleeding.The characteristics and clinical parameters were collected and recorded.Data on procedure success rate,variation in portal vein pressure,rebleeding,hepatic encephalopathy(HE),stent stenosis,and overall mortality were analyzed.Results:A total of 189 patients were included in this study(39 in type 1,84 in type 2,48 in type 3,18 in type 4).The TIPS procedure success rate was 86.2%.The success rate was significantly different among the four types(89.7%vs.88.1%vs.83.3%vs.77.8%,P=0.001).In the TIPS success group,portal vein pressure was significantly reduced from 27.15±6.59 to 19.74±6.73 mm Hg after the procedure(P<0.001)and the rebleeding rate was significantly lower than that of the fail group(14.7%vs.30.8%,P=0.017).In addition,there were no significant differences in HE rate(30.7%vs.26.9%,P=0.912)or overall mortality(12.9%vs.19.2%,P=0.403)between the TIPS success group and the fail group.In the TIPS success group,we found that the occurrence of HE was significantly different(P=0.020)among the four types,while there were no significant differences in rebleeding rate(P=0.669),stent stenosis rate(P=0.056),or overall mortality(P=0.690).Conclusions:TIPS was safe and effective in decreasing portal vein pressure and rebleeding rate in patients with CPVT.
文摘AIM To investigate whether the preoperative neutrophil-tolymphocyte ratio(NLR) could predict the prognosis of hepatocellular carcinoma(HCC) patients with portal/hepatic vein tumor thrombosis(PVTT/HVTT) after hepatectomy.METHODS The study population included 81 HCC patients who underwent hepatectomy and were diagnosed with PVTT/HVTT based on pathological examination. The demographics, laboratory analyses, and histopathology data were analyzed.RESULTS Overall survival(OS) and disease-free survival(DFS) were determined in the patients with a high(> 2.9) and low(≤ 2.9) NLR. The median OS and DFS duration in the high NLR group were significantly shorter than those in the low NLR group(OS: 6.2 mo vs 15.7 mo, respectively, P = 0.007; DFS: 2.2 mo vs 3.7 mo, respectively, P = 0.039). An NLR > 2.9 was identified as an independent predictor of a poor prognosis of OS(P = 0.034, HR = 1.866; 95%CI: 1.048-3.322) in uni-and multivariate analyses. Moreover, there was a significantly positive correlation between the NLR and the Child-Pugh score(r = 0.276, P = 0.015) and the maximum diameter of the tumor(r = 0.435, P < 0.001). Additionally, the NLR could enhance the prognostic predictive power of the CLIP score for DFS in these patients. CONCLUSION The preoperative NLR is a prognostic predictor after hepatectomy for HCC patients with PVTT/HVTT. NLR > 2.9 indicates poorer OS and DFS.
文摘Background: Since advanced hepatocellular carcinoma (HCC) is potentially fatal, and patients’ quality of life (QOL) often deteriorates during their treatment, improving the prognosis and QOL of patients given chemotherapy is very important. In addition, cost-effective treatments are highly desirable when chemotherapy must be given repeatedly. The aim of this study was to evaluate the efficacy and usefulness of 5-fluorouracil (5-FU) and high-concentration cisplatin by short-term hepatic arterial infusion chemotherapy (3-day FPL) in advanced HCC patients. Methods: Thirty patients with unresectable advanced HCC were enrolled. The patients underwent hepatic arterial infusion chemotherapy via the implanted port system with 5-FU on days 1 - 3 and a fine-powder formulation of cisplatin in suspended pre-warmed lipiodol on day 2 every 4 to 10 weeks. Tumor response was assessed one month later with CT. Results: All patients had evidence of portal vein invasion (Vp2-4). Four patients achieved a complete response (CR), 8 patients achieved a partial response (PR), and 7 patients had stable disease (SD). The median progression-free survival (PFS) and overall survival (OS) were 198 days and 452 days, respectively. The OS was significantly longer in the successful disease control group (CR, PR, and SD) than in the progressive disease group (P < 0.005). Conclusions: Three-day FPL was effective and tolerable in advanced HCC patients due to its shorter time of administration than conventional FP therapy. Therefore, repetitive 3-day FPL appears useful and contributes to improving the prognosis and QOL of patients with advanced HCC. In addition, this protocol is a cost-effective treatment.
文摘BACKGROUND While tuberculosis(TB)itself is a common disease,isolated TB of the liver is a rare entity.Tubercular involvement of the liver is more commonly a part of a disseminated disease of the hepatic parenchyma.In contrast,isolated hepatic TB spread through the portal vein from the gastrointestinal tract is seldom encountered in clinical practice,with only a few sporadic cases and short series available in the current literature.Vascular complications,such as portal vein thrombosis(PVT),have rarely been reported previously.CASE SUMMARY A 22-year-old man was hospitalized with complaints of a 3-mo history of fever and weight loss of approximately 10 kg.He had a 10-year hepatitis B virus(HBV)infection in his medical history.Contrast-enhanced computed tomography(CECT)confirmed hepatosplenomegaly,with hypodensity of the right lobe of the liver and 2.1 cm thrombosis of the right branch of the portal vein.A liver biopsy showed epithelioid granulomas with a background of caseating necrosis.ZiehlNelson staining showed acid-fast bacilli within the granulomas.The patient was diagnosed with isolated hepatic TB with PVT.Anti-TB therapy(ATT),including isoniazid,rifapentine,ethambutol,and pyrazinamide,was administered.Along with ATT,the patient was treated with entecavir as an antiviral medication against HBV and dabigatran as an anticoagulant.He remained asymptomatic,and follow-up sonography of the abdomen at 4 mo showed complete resolution of the PVT.CONCLUSION Upon diagnosis of hepatic TB associated with PVT and HBV coinfection,ATT and anticoagulants should be initiated to prevent subsequent portal hypertension.Antiviral therapy against HBV should also be administered to prevent severe hepatic injury.
文摘The prognosis of hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT) is very poor although sorafenib is recommended as the first-line treatment. Therefore, an effective treatment regime is needed for treating HCC with PVTT. This review summarized seven potential treatment regimes which including transarterial chemoembolization (TACE), TACE combined with sorafenib, TACE combined with radiotherapy (RT), hepatectomy, hepatic arterial infusion chemotherapy (HAIC), HAIC combined with sorafenib and HAIC combined with RT in the treatment of HCC with PVTT. In conclusion, hepatectomy or the combination of HAIC and sorafenib may be a more effective modality in the treatment of HCC patients with type I - II PVTT. HAIC combined with or without sorafenib/RT or the combination of RT and TACE is an alternative treatment choice for HCC patients with type III - IV PVTT. Further randomized controlled studies are warranted.
文摘An estimated 300 million people worldwide suffer from chronic hepatitis C with a prevalence of 0.8%-1.0% of the general population in Canada. An increasing pool of evidence exists supporting the use of pegylated-interferon (pegIFN) and ribavirin combination therapy for hepatitis C. We report a 49-year old male of North American aboriginal descent with chronic hepatitis C (genotype 2b). Biopsy confirmed that he had cirrhosis with a 2-wk history of left eye pain and decreased visual acuity. He developed retinal vein thrombosis after 16 of 24 wk of pegIFN-α 2a and ribavirin combination therapy. He was urgently referred to a retinal specialist and diagnosed with non-ischemic central retinal vein occlusion of the left eye. PegIFN and ribavirin combination therapy was discontinued and HCV RNA was undetectable after 16 wk of treatment. Hematologic investigations revealed that the patient was a factor V Leiden heterozygote with mildly decreased protein C activity. Our patient had a number of hypercoagulable risk factors, including factor V Leiden heterozygosity, cirrhosis, and hepatitis C that alone would have most likely remained clinically silent. We speculate that in the setting of pegIFN treatment, these risk factors may coalesce and cause the retinal vein thrombosis.
文摘The natural history of hepatocellular carcinoma(HCC)with portal vein tumor thrombosis(PVTT)is dismal(approximately 2-4 mo),and PVTT is reportedly found in 10%-40%of HCC patients at diagnosis.According to the Barcelona Clinic Liver Cancer(BCLC)Staging System(which is the most widely adopted HCC management guideline),sorafenib is the standard of care for advanced HCC(i.e.,BCLC stage C)and the presence of PVTT is included in this category.However,sorafenib treatment only marginally prolongs patient survival and,notably,its therapeutic efficacy is reduced in patients with PVTT.In this context,there have been diverse efforts to develop alternatives to current standard systemic chemotherapies or combination treatment options.To date,many studies on transarterial chemoembolization,3-dimensional conformal radiotherapy,hepatic arterial chemotherapy,and transarterial radioembolization report better overall survival than sorafenib therapy alone,but their outcomes need to be verified in future prospective,randomized controlled studies in order to be incorporated into current treatment guidelines.Additionally,combination strategies have been applied to treat HCC patients with PVTT,with the hope that the possible synergistic actions among different treatment modalities would provide promising results.This narrative review describes the current status of the management options for HCC with PVTT,with a focus on overall survival.
文摘BACKGROUND The use of umbilical venous catheters(UVCs)in the perinatal period may be associated with severe complications,including the occurrence of portal vein thrombosis(PVT).AIM To assess the incidence of UVC-related PVT in infants with postnatal age up to three months.METHODS A systematic and comprehensive database searching(PubMed,Cochrane Library,Scopus,Web of Science)was performed for studies from 1980 to 2020(the search was last updated on November 28,2020).We included in the final analyses all peer-reviewed prospective cohort studies,retrospective cohort studies and casecontrol studies.The reference lists of included articles were hand-searched to identify additional studies of interest.Studies were considered eligible when they included infants with postnatal age up to three months with UVC-associated PVT.Incidence estimates were pooled by using random effects meta-analyses.The quality of included studies was assessed using the Newcastle-Ottawa scale.The systematic review was performed according to the Preferred Reporting Items for Systematic reviews and Meta-Analysis(PRISMA)guidelines.RESULTS Overall,16 studies were considered eligible and included in the final analyses.The data confirmed the relevant risk of UVC-related thrombosis.The mean pooled incidence of such condition was 12%,although it varied across studies(0%-49%).In 15/16 studies(94%),diagnosis of thrombosis was made accidentally during routine screening controls,whilst in 1/16 study(6%)targeted imaging assessments were carried out in neonates with clinical concerns for a thrombus.Tip position was investigated by abdominal ultrasound(US)alone in 1/16(6%)studies,by a combination of radiography and abdominal US in 14/16(88%)studies and by a combination of radiography,abdominal US and echocardiography in 1/16(6%)studies.CONCLUSION To the best of our knowledge,this is the first systematic review specifically investigating the incidence of UVC-related PVT.The use of UVCs requires a high index of suspicion,because its use is significantly associated with PVT.Well-designed prospective studies are required to assess the optimal approach to prevent UVCrelated thrombosis of the portal system.
文摘Pulmonary embolism occurs more frequently after hepatectomy than previously thought but is infrequently associated with peripheral deep vein thrombosis. In this paper, we report 2 cases of postoperative hepatic vein thrombosis after liver resection. Both patients had undergone major hepatectomy of a non-cirrhotic liver largely exposing the middle hepatic vein. Clots were incidentally found in the middle hepatic vein 4 and 17 d after surgery despite routine systemic thrombo-prophylaxis with low molecular weight heparin. Coagulation of the transition plan in a context of mutation of the prothrombin gene and inflammation induced biloma were the likely predisposing conditions. Clots disappeared following curative anticoagulation. We conclude that thrombosis of hepatic veins may occur after liver resection and is a potential source of pulmonary embolism.
文摘AIM To review current literature of thrombosis prophylaxis in pediatric liver transplantation(PLT) as thrombosis remains a critical complication.METHODS Studies were identified by electronic search of MEDLINE, EMBASE and Cochrane Library(CENTRAL) databases until March 2018. The search was supplemented by manually reviewing the references of included studies and the references of the main published systematic reviews on thrombosis and PLT. We excluded from this review case report, small case series, commentaries, conference abstracts, papers which describing less than 10 pediatric liver transplants/year and articles published before 1990. Two reviewers performed study selection independently, with disagreements solved through discussion and by the opinion of a third reviewer when necessary.RESULTS Nine retrospective studies were included in this review. The overall quality of studies was poor. A pooled analysis of results from studies was not possible due to the retrospective design and heterogeneity of included studies. We found an incidence of portal vein thrombosis(PVT) ranging from 2% to 10% in pediatric living donorliver transplantation(LDLT) and from 4% to 33% in pediatric deceased donor liver transplantation(DDLT). Hepatic artery thrombosis(HAT) was observed mostly in mixed LDLT and DDLT pediatric population with an incidence ranging from 0% to 29%. In most of the studies Doppler ultrasonography was used as a first line diagnostic screening for thrombosis. Four different surgical techniques for portal vein anastomosis were reported with similar efficacy in terms of PVT reduction. Reduced size liver transplant was associated with a low risk of both PVT(incidence 4%) and HAT(incidence 0%, P < 0.05). Similarly, aortic arterial anastomosis without graft interposition and microsurgical hepatic arterial reconstruction were associated with a significant reduced HAT incidence(6% and 0%, respectively). According to our inclusion and exclusion criteria, we did not find eligible studies that evaluated pharmacological prevention of thrombosis. CONCLUSION Poor quality retrospective studies show the use of tailored surgical strategies might be useful to reduce HAT and PVT after PLT; prospective studies are urgently needed.
文摘BACKGROUND Thromboembolic complications are relatively common causes of increased morbidity and mortality in the perioperative period in liver transplant patients.Early postoperative portal vein thrombosis(PVT,incidence 2%-2.6%)and early hepatic artery thrombosis(HAT,incidence 3%-5%)have a poor prognosis in transplant patients,having impacts on graft and patient survival.In the present study,we attempted to identify the predictive factors of these complications for early detection and therefore monitor more closely the patients most at risk of thrombotic complications.AIM To investigate whether intraoperative thromboelastography(TEG)is useful in detecting the risk of early postoperative HAT and PVT in patients undergoing liver transplantation(LT).METHODS We retrospectively collected thromboelastographic traces,in addition to known risk factors(cold ischemic time,intraoperative requirement for red blood cells and fresh-frozen plasma transfusion,prolonged operating time),in 27 patients,selected among 530 patients(≥18 years old),who underwent their first LT from January 2002 to January 2015 at the Liver University Transplant Center and developed an early PVT or HAT(case group).Analyses of the TEG traces were performed before anesthesia and 120 min after reperfusion.We retrospectively compared these patients with the same number of nonconsecutive control patients who underwent LT in the same study period without developing these complications(1:1 match)(control group).The chosen matching parameters were:Patient graft and donor characteristics[age,sex,body mass index(BMI)],indication for transplantation,procedure details,United Network for Organ Sharing classification,BMI,warm ischemia time(WIT),cold ischemia time(CIT),the volume of blood products transfused,and conventional laboratory coagulation analysis.Normally distributed continuous data are reported as the mean±SD and compared using one-way Analysis of Variance(ANOVA).Nonnormally distributed continuous data are reported as the median(interquartile range)and compared using the Mann-Whitney test.Categorical variables were analyzed with Chi-square tests with Yates correction or Fisher’s exact test depending on best applicability.IBM SPSS Statistics version 24(SPSS Inc.,Chicago,IL,United States)was employed for statistical analysis.Statistical significance was set at P<0.05.RESULTS Postoperative thrombotic events were identified as early if they occurred within 21 d postoperatively.The incidence of early hepatic artery occlusion was 3.02%,whereas the incidence of PVT was 2.07%.A comparison between the case and control groups showed some differences in the duration of surgery,which was longer in the case group(P=0.032),whereas transfusion of blood products,red blood cells,fresh frozen plasma,and platelets,was similar between the two study groups.Thromboelastographic parameters did not show any statistically significant difference between the two groups,except for the G value measured at basal and 120’postreperfusion time.It was higher,although within the reference range,in the case group than in the control group(P=0.001 and P<0.001,respectively).In addition,clot lysis at 60 min(LY60)measured at 120’postreperfusion time was lower in the case group than in the control group(P=0.035).This parameter is representative of a fibrinolysis shutdown(LY60=0%-0.80%)in 85%of patients who experienced a thrombotic complication,resulting in a statistical correlation with HAT and PVT.CONCLUSION The end of surgery LY60 and G value may identify those recipients at greater risk of developing early HAT or PVT,suggesting that they may benefit from intense surveillance and eventually anticoagulation prophylaxis in order to prevent these serious complications after LT.

文摘Background Unresectable hepatocellular carcinoma(HCC)has a poor prognosis.According to the HCC management guidelines in China,the standard treatment of Barcelona Clinic Liver Cancer(BCLC)stage B or C HCC with portal vein tumour thrombosis(PVTT)is chemoembolization.However,some patients with BCLC stage B or C HCC with PVTT respond poorly to chemoembolization.We aimed to compare tumour responses and survival benefits between patients with unresectable HCC with or without PVTT.Methods We reviewed 119 consecutive patients with unresectable HCC with PVTT(n=67)and without PVTT(n=52)who underwent hepatic arterial infusion of oxaliplatin plus raltitrexed between January 2018 and April 2021.Overall survival,progression-free survival,tumour responses,and adverse events were compared between the groups.Results There were no significant between-group differences in the objective response rates and median progression-free survival.The median overall survival was significantly longer in the group without PVTT than in that with PVTT(17.0 vs 10.4 months,respectively;P=0.024).Conclusion Hepatic arterial infusion of oxaliplatin plus raltitrexed may be efficacious in patients with unresectable HCC with or without PVTT.
文摘BACKGROUND: In order to preserve functional liver parenchyma, extended central hepatectomy (segments 4, 5, 7 and 8 resection) was proposed for the management of centrally located hepatocellular carcinoma invading the right and middle hepatic veins, reconstructing segment 6 outflow in the absence of the thick inferior right hepatic vein. The present study was to describe our surgical techniques of extended central hepatectomy.METHODS: Between 2008 and 2012, 5 patients with centrally located hepatocellular carcinoma invading or in the vicinity of the right and middle hepatic veins underwent extended central hepatectomy. The thick inferior right hepatic vein was preserved during dissection. Gore-Tex graft was used for segment 6 outflow reconstruction in the absence of the thick inferior right hepatic vein.RESULTS: The mean future remnant liver volume for segments 2 and 3 was 28% versus 45% on segment 6 preservation. The mean tumor diameter was 7.4 cm. The thick inferior right hepatic vein was found in 1 patient. Outflow reconstruction from segment 6 was performed in 4 patients. Postoperative complications included bile leakage (1 patient), pleural effusion (2) and liver failure (1). The rate of graft patency was 75%. There was no perioperative mortality.CONCLUSION: Extended central hepatectomy is a safe alternative for extended hepatic resection in selected patients attempting to preserve the functional liver parenchyma.
