BACKGROUND Venous thromboembolism(VTE)is a potentially fatal complication of hepatectomy.The use of postoperative prophylactic anticoagulation in patients who have undergone hepatectomy is controversial because of the risk of postoperative bleeding.Therefore,we hypothesized that monitoring plasma D-dimer could be useful in the early diagnosis of VTE after hepatectomy.AIM To evaluate the utility of monitoring plasma D-dimer levels in the early diagnosis of VTE after hepatectomy.METHODS The medical records of patients who underwent hepatectomy at our institution between January 2017 and December 2020 were retrospectively analyzed.Patients were divided into two groups according to whether or not they developed VTE after hepatectomy,as diagnosed by contrast-enhanced computed tomography and/or ultrasonography of the lower extremities.Clinicopathological factors,including demographic data and perioperative D-dimer values,were compared between the two groups.Receiver operating characteristic curve analysis was performed to determine the D-dimer cutoff value.Univariate and multivariate analyses were performed using logistic regression analysis to identify significant predictors.RESULTS In total,234 patients who underwent hepatectomy were,of whom(5.6%)were diagnosed with VTE following hepatectomy.A comparison between the two groups showed significant differences in operative time(529 vs 403 min,P=0.0274)and blood loss(530 vs 138 mL,P=0.0067).The D-dimer levels on postoperative days(POD)1,3,5,7 were significantly higher in the VTE group than in the non-VTE group.In the multivariate analysis,intraoperative blood loss of>275 mL[odds ratio(OR)=5.32,95%confidence interval(CI):1.05-27.0,P=0.044]and plasma D-dimer levels on POD 5≥21μg/mL(OR=10.1,95%CI:2.04-50.1,P=0.0046)were independent risk factors for VTE after hepatectomy.CONCLUSION Monitoring of plasma D-dimer levels after hepatectomy is useful for early diagnosis of VTE and may avoid routine prophylactic anticoagulation in the postoperative period. 展开更多

Background: Venous thromboembolism (VTE) is a major public health problem due to its increasing frequency, mortality and management cost. This cost may require major financial efforts from patients, especially in developing countries like ours where less than 7% of the population has health insurance. This study aimed to estimate the direct cost of managing VTE in three reference hospitals in Yaoundé. Methods: This was a cross-sectional retrospective study over a three-year period (from January 1st 2018 to December 31 2020) carried out in the Cardiology departments of the Central and General Hospitals, and the Emergency Centre of the city of Yaoundé. All patients managed during the study period for deep vein thrombosis and pulmonary embolism confirmed by venous ultrasound coupled with Doppler and computed tomography pulmonary angiography respectively were included. For each patient, we collected sociodemographic and clinical data as well as data on the cost of consultation, hospital stay, workups and medications. These data were analysed using SPSS version 23.0. Results: A total of 92 patient’s records were analysed. The median age was 60 years [48 - 68] with a sex ratio of 0.53. The median direct cost of management of venous thromboembolism was 766,375 CFAF [536,455 - 1,029,745] or $1415 USD. Management of pulmonary embolism associated with deep vein thrombosis was more costly than isolated pulmonary embolism or deep vein thrombosis. Factors influencing the direct cost of management of venous thromboembolism were: hospital structure (p = 0.015), health insurance (p 0.001), type of pulmonary embolism (p = 0.021), and length of hospital stay (p = 0.001). Conclusion: Management of VTE is a major financial burden for our patients and this burden is influenced by the hospital structure, health insurance, type of pulmonary embolism and length of hospital stay. 展开更多

Background: Venous thromboembolism (VTE) is among the leading causes of hospital-related disability-adjusted life years lost. We aimed to determine the prevalence and determinants of functional capacity impairment six to twelve months after an acute VTE event. Methods: This was a cross-sectional study conducted between January and April 2021 in two referral hospitals of Yaoundé, including consenting adult patients admitted to these hospitals six to twelve months ago for VTE. We excluded dead patients and those with any comorbidity or symptoms limiting physical activity. The functional outcome was assessed with the six-minute walk test. Functional capacity impairment was defined as walking distance lower than the expected value. Results: We included 27 cases in this study with a mean age of 53.2 ± 14.4 years. The prevalence of functional capacity impairment was 29.6% (95% CI: 14.8 - 48.1). Factors associated with poor functional outcome were obesity (OR: 59.5;95% CI: 4.6 - 767.2;p - 207.4;p = 0.017), massive PE (OR: 30;95% CI: 2.5 - 354;p = 0.004), and poor adherence to treatment (OR: 30.3;95% CI: 2.5 - 333.3;p = 0.004). Conclusion: Functional capacity impairment is common in the medium-term after VTE and factors associated with this poor outcome are obesity, the severity of the VTE, and poor adherence to treatment. 展开更多

Inflammatory bowel disease(IBD),including Crohn’s disease(CD)and ulcerative colitis(UC),is a chronic inflammatory disease of the digestive tract with increasing prevalence globally.Although venous thromboembolism(VTE)is a major complication in IBD patients,it is often underappreciated with limited tools for risk stratification.AIM To estimate the proportion of VTE among IBD patients and assess genetic risk factors(monogenic and polygenic)for VTE.METHODS Incident VTE was followed for 8465 IBD patients in the UK Biobank(UKB).The associations of VTE with F5 factor V leiden(FVL)mutation,F2 G20210A prothrombin gene mutation(PGM),and polygenic score(PGS003332)were tested using Cox hazards regression analysis,adjusting for age at IBD diagnosis,gender,and genetic background(top 10 principal components).The performance of genetic risk factors for discriminating VTE diagnosis was estimated using the area under the receiver operating characteristic curve(AUC).RESULTS The overall proportion of incident VTE was 4.70%in IBD patients and was similar for CD(4.46%),UC(4.49%),and unclassified(6.42%),and comparable to that of cancer patients(4.66%)who are well-known at increased risk for VTE.Mutation carriers of F5/F2 had a significantly increased risk for VTE compared to non-mutation carriers,hazard ratio(HR)was 1.94,95%confidence interval(CI):1.42-2.65.In contrast,patients with the top PGS decile had a considerably higher risk for VTE compared to those with intermediate scores(middle 8 deciles),HR was 2.06(95%CI:1.57-2.71).The AUC for differentiating VTE diagnosis was 0.64(95%CI:0.61-0.67),0.68(95%CI:0.66-0.71),and 0.69(95%CI:0.66-0.71),respectively,for F5/F2 mutation carriers,PGS,and combined.CONCLUSION Similar to cancer patients,VTE complications are common in IBD patients.PGS provides more informative risk information than F5/F2 mutations(FVL and PGM)for personalized thromboprophylaxis. 展开更多

BACKGROUND Protein C deficiency is typically associated with venous thromboembolism;however,arterial thrombosis has been reported in several cases.We report the case of a patient with pulmonary thromboembolism and deep vein thrombosis following acute myocardial infarction with high thrombus burden.CASE SUMMARY A 40-year-old man was diagnosed with pulmonary thromboembolism and deep vein thrombosis without any provoking factors.The patient was treated with anticoagulants for six months,which were then discontinued.Three months after the discontinuation of anticoagulant therapy,the patient was hospitalized with chest pain and diagnosed with acute myocardial infarction with high thrombus burden.Additional tests revealed protein C deficiency associated with thrombophilia.The patient was treated with anticoagulants combined with dual antiplatelet agents for 1 year after percutaneous coronary intervention,and no recurrent events were reported during a follow-up period of 5 years.CONCLUSION Recurrent thromboembolic events including acute myocardial infarction with thrombus should be considered an alarming sign of thrombophilia. 展开更多

BACKGROUND Nonalcoholic fatty liver disease(NAFLD)is the most common cause of chronic liver disease worldwide.Studies have shown a strong association between nonalcoholic steatohepatitis(NASH)cirrhosis and portal vein thrombosis.Specifically,there is paucity of data on the association of NASH and venous thromboembolism(VTE),with one such study predicting a 2.5-fold increased risk for VTE compared to other liver diseases in hospitalized patients.The mechanism is believed to be a hepatocellular injury,which causes a chronic inflammatory state leading to the unregulated activation of procoagulant factors.There has been no prior analysis of the degree of steatosis and fibrosis(measured using transient elastography,commonly known as FibroScan)in NASH and its association with VTE.AIM To examine the association between the degree of hepatic steatosis and fibrosis,quantified by transient elastography,and the incidence of VTE in patients with NASH.METHODS In our case-control study,we included patients with a documented diagnosis of NASH.We excluded patients with inherited thrombophilia,hemoglobinopathy,malignancy,alcohol use disorder,autoimmune hepatitis,and primary biliary cirrhosis.The collected data included age,demographics,tobacco use,recreational drug use,medical history,and vibration controlled transient elastography scores.VTE-specific data included the location,type of anticoagulant,need for hospital stay,and history of VTE recurrence.Steatosis was categorized as S0-S1(mild)and S2-S3(moderate to severe)based on the controlled attenuation parameter score.Fibrosis was classified based on the kilopascal score and graded as F0-F1(Metavir stage),F2,F3,and F4(cirrhosis).χ^(2) and Mann-Whitney U tests were used for the qualitative and quantitative variable analyses,respectively.Furthermore,we performed a logistic regression using VTE as the dependent variable.RESULTS A total of 415 patients were analyzed,and 386 met the inclusion criteria.51 and 335 patients were included in the VTE and non-VTE groups,respectively.Patients with VTE had a mean age of 60.63 years compared to 55.22 years in the non-VTE group(P<0.014).Patients with VTE had a higher body mass index(31.14 kg/m²vs 29.30 kg/m²)and a higher prevalence of diabetes mellitus(29.4%vs 13.1%).The history of NASH was significantly higher in the VTE group(45.1%vs 30.4%,P<0.037).Furthermore,moderate-to-severe steatosis was significantly higher in the VTE group(66.7%vs 47.2%,P<0.009).Similarly,the F2-F4 fibrosis grade had a prevalence of 58.8%in the VTE group compared to 38.5%in the non-VTE group(P<0.006).On logistic regression,using VTE as a dependent variable,diabetes mellitus had an odds ratio(OR)=1.702(P<0.015),and F2-F4 fibrosis grade had an OR=1.5(P<0.033).CONCLUSION Our analysis shows that NASH is an independent risk factor for VTE,especially deep vein thrombosis.There was a statistically significant association between the incidence of VTE,moderate-to-severe steatosis,and fibrosis.All hospitalized patients should be considered for medical thromboprophylaxis,particularly those with NASH. 展开更多

Introduction: Thrombosis is a major cause of maternal death worldwide. During pregnancy, the risk of venous thromboembolism (VTE) increases fourfold to five-fold and contributes towards maternal morbidity and mortality. Sri Lanka does not have a proper assessment tool to detect and manage it in the antenatal care. Objectives: To identify risks factors for VTE among pregnant mothers, postpartum mothers according to RCOG (Royal College of Obstetricians) risk categorization and to assess the requirement of thromboprophylaxis. Method: A cross sectional study was conducted at the antenatal clinics and obstetrics and gynaecology wards (ward 2, 5, 8) of De Soysa Hospital for Women in 2021. Obstetric thromboprophylaxis risk assessment tool recommended by the RCOG was used for the risk assessment of pregnant mothers during the antenatal and postpartum period. Results: In antenatal period, obesity (BMI > 35), age more than 35 years and parity more than 3 were the commonest risk factors. Out of 404 mothers, 67.33% did not have any risk factors. Among others, 18.56%, 0.40%, 2.72%, 0.99% had a score of 1, 2, 3 and 4 respectively. Patients with intermediate (0.99%) and high risk (2.72%) were commenced on thromboprophylaxis from 28 weeks. The low-risk category was not started on any treatment (28.96%, n = 97). Approximately 96% of mothers did not require any thromboprophylaxis during antenatal period. Another 404 postnatal mothers were recruited for the study group. Elective caesarean section and caesarean section during labour were the main risks identified other than pre-existing antenatal risks. 39.95 % of mothers did not have any risk factors and 37.22% of mothers had a score of 1. Conclusions: VTE risk assessment tool can be implemented at national level to detect patients at risk of VTE and improve maternal care. 展开更多

BACKGROUND The May-Hegglin anomaly is among a group of genetic disorders known as MYH9-related disease.Patients with inherited platelet disorders such as May-Hegglin anomaly are at a variably increased risk for bleeding due to a combination of platelet dysfunction and thrombocytopenia.Patients admitted to the hospital with coronavirus disease 2019(COVID-19)infection are at an increased risk for a venous thromboembolism event(VTE).The National Institutes of Health COVID-19 treatment guidelines recommend using a prophylactic dose of heparin as VTE prophylaxis for adults who are receiving high-flow oxygen.We describe a patient admitted for COVID-19 infection with pneumonia and a history of May-Hegglin anomaly.The patient presented a challenge to determine prophylactic anticoagulation as there are no clear guidelines for this patient population.CASE SUMMARY Herein,we describe the case of a 39-year-old woman admitted with acute hypoxic respiratory failure secondary to COVID-19 pneumonia.She had a history of May-Hegglin anomaly and demonstrated risk for bleeding since childhood,including a life-threatening bleeding event at the age of 9 years requiring blood and platelet transfusions.Her baseline platelet count was 40-50×109/L throughout her adult life.Her family history was also notable for May-Hegglin disorder in her mother,maternal uncle,maternal grandfather and her son.Computed tomography/pulmonary angiography revealed bilateral consolidative opacities consistent with multifocal pneumonia.Complete blood count was notable for platelet count of 54×109/L.She was admitted for inpatient respiratory support with high-flow oxygen per nasal cannula and was managed with guideline-directed therapy for COVID-19,including baricitinib and dexamethasone.The Hematology/Oncology consultation team was requested to assist with management of VTE prophylaxis in the setting of active COVID-19 infection and an inherited bleeding disorder.After review of the literature and careful consideration of risks and benefits,it was decided to treat the patient with prophylactic enoxaparin.She was closely monitored in the hospital for bleeding and worsening thrombocytopenia.She had no bleeding or signs of VTE.Her respiratory status improved,and she was discharged home after 5 d of hospitalization with supplemental oxygen by nasal cannula and dexamethasone.At the 6-month follow-up,the patient successfully discontinued her home oxygen use after only a few weeks following discharge.CONCLUSION The patient presented a challenge to determine prophylactic anticoagulation as anticoagulation guidelines exist for patients with COVID-19,but there are no clear guidelines for management of patients with COVID-19 and inherited bleeding disorders,particularly those with MYH9-related disease.She was discharged after recovery from the COVID-19 infection without bleeding or thrombosis.As there are no published guidelines for this situation,we present a pragmatic,informed approach to a patient with MYH9-related disease who had an indication for anticoagulation. 展开更多

The coexistence of venous thromboembolism(VTE)within patients with cancer,known as cancer-associated thrombosis(CAT),stands as a prominent cause of mortality in this population.Over recent years,the incidence of VTE has demonstrated a steady increase across diverse tumor types,influenced by several factors such as patient management,tumor-specific risks,and treatment-related aspects.Furthermore,mutations in specific genes have been identified as potential contributors to increased CAT occurrence in particular cancer subtypes.We conducted an extensive review encompassing pivotal historical and ongoing studies on CAT.This review elucidates the risks,mechanisms,reliable markers,and risk assessment methodologies that can significantly guide effective interventions in clinical practice. 展开更多

Patients with inflammatory bowel disease(IBD)are at an increased risk for venous thromboembolism(VTE).VTE events carry significant morbidity and mortality,and have been associated with worse outcomes in patients with IBD.Studies have suggested that the hypercoagulable nature of the disease stems from a complex interplay of systems that include the coagulation cascade,natural coagulation inhibitors,fibrinolytic system,endothelium,immune system,and platelets.Additionally,clinical factors that increase the likelihood of a VTE event among IBD patients include older age(though some studies suggest younger patients have a higher relative risk of VTE,the incidence in this population is much lower as compared to the older IBD patient population),pregnancy,active disease,more extensive disease,hospitalization,the use of certain medications such as corticosteroids or tofacitinb,and IBD-related surgeries.Despite the increased risk of VTE among IBD patients and the safety of pharmacologic prophylaxis,adherence rates among hospitalized IBD patients appear to be low.Furthermore,recent data suggests that there is a population of high risk IBD patients who may benefit from post-discharge prophylaxis.This review will provide an overview of patient specific factors that affect VTE risk,elucidate reasons for lack of VTE prophylaxis among hospitalized IBD patients,and focus on recent data describing those at highest risk for recurrent VTE post-hospital discharge. 展开更多

AIM: To assess the safety and effectiveness of prophylaxis for venous thromboembolism (VTE) in a large population of patients with hepatocellular carcinoma (HCC) on cirrhosis.METHODS: Two hundred and twenty nine consecutive cirrhotic patients with HCC who underwent hepatic resection were retrospectively evaluated to assess whether there was any difference in the incidence of thrombotic or hemorrhagic complications between those who received and those who did not receive prophylaxis with low-molecular weight heparin.Differences and possible effects of the following parameters were investigated: age,sex,Child-Pugh and model for end-stage liver disease (MELD) score,platelet count,presence of esophageal varices,type of hepatic resection,duration of surgery,intraoperative transfusion of blood and fresh frozen plasma (FFP),body mass index,diabetes and previous cardiovascular disease.RESULTS: One hundred and fifty seven of 229 (68.5%) patients received antithromboembolic prophylaxis (group A) while the remaining 72 (31.5%) patients did not (group B).Patients in group B had higher Child-Pugh and MELD scores,lower platelet counts,a higher prevalence of esophageal varices and higher requirements for intraoperative transfusion of FFP.The incidence of VTE and postoperative hemorrhage was 0.63% and 3.18% in group A and 1.38% and 1.38% in group B,respectively;these differences were not significant.None of the variables analyzed including prophylaxis proved to be risk factors for VTE,and only the presence of esophageal varices was associated with an increased risk of bleeding.CONCLUSION: Prophylaxis is safe in cirrhotic patients without esophageal varices;the real need for prophylaxis should be better assessed. 展开更多

Venous thromboembolism(VTE)refers to a hypercoa-gulable state that remains an important and preven-table factor in the surgical treatment of malignancies.VTE includes two identical entities with regards to deep vein thrombosis and pulmonary embolism.The incidence of VTE after major abdominal interventions for gastro-intestinal,hepato-biliary and pancreatic neoplastic disor-ders is as high as 25%without prophylaxis.Prophylactic use of classic or low-molecular-weight heparin,anti-Xa factors,antithrombotic stocking,intermittent pneumatic compression devices and early mobilization have been described.Nevertheless,thromboprophylaxis is often dis-continued after discharge,although a serious risk may persist long after the initial triggering event,as the coagu-lation system remains active for at least 14 d post-opera-tively.The aim of this review is to evaluate the results of the current practice of VTE prevention in cancer patients undergoing major abdominal surgical operations,with special attention to adequately elucidated guidelinesand widely accepted protocols.In addition,the recent literature is presented in order to provide an update on the current concepts concerning the surgical manage-ment of the disease. 展开更多

Inflammatory bowel disease(IBD)patients have an increased risk of venous thromboembolism(VTE),which represents a significant cause of morbidity and mortality.The most common sites of VTE in IBD patients are the deep veins of the legs and pulmonary system,followed by the portal and mesenteric veins.However,other sites may also be involved,such as the cerebrovascular and retinal veins.The aetiology of VTE is multifactorial,including both inherited and acquired risk factors that,when simultaneously present,multiply the risk to the patient.VTE prevention involves correcting modifiable risk factors,such as disease activity,vitamin deficiency,dehydration and prolonged immobilisation.The role of mechanical and pharmacological prophylaxis against VTE using anticoagulants is also crucial.However,although guidelines recommend thromboprophylaxis for IBD patients,this method is still poorly implemented because of concerns about its safety and a lack of awareness of the magnitude of thrombotic risk in these patients.Further efforts are required to increase the rate of pharmacological prevention of VTE in IBD patients to avoid preventable morbidity and mortality. 展开更多

AIM To summarize the current knowledge on vascular complications and deep venous thrombosis(DVT) prophylaxis after anterior cruciate ligament(ACL) reconstruction.METHODS A systematic review was conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses statement. MEDLINE, EMBASE, Cochrane,Web of Science, CINAHL, PubMed publisher, and Google scholar medical literature databases were searched up to November 10, 2015. Any arthroscopic surgical method of primary or revision intra-articular ACL reconstruction of all graft types in humans was included. A risk of bias assessment was determined.RESULTS Fourty-seven studies were included in the review.Pseudaneurysms were the most frequently reported arterial complication after ACL reconstruction, irrespective of graft type or method of graft fixation with an incidence of 0.3%. The time to diagnosis of arterial complications after ACL reconstruction varied from days to mostly weeks but even years. After ACL reconstruction without thromboprophylaxis, the incidence of DVT was 9.7%, of which 2.1% was symptomatic. The incidence of pulmonary embolism was 0.1%. Tourniquet time > 2 h was related to venous thromboembolism.Thromboprophylaxis is indicated in patients with risk factors for venous thromboembolism.CONCLUSION After ACL reconstruction, the incidence of arterial complications,symptomatic DVT and pulmonary embolism was 0.3%, 2.1% and 0.1% respectively. Arterial complications may occur with all types of arthroscopic ACL reconstruction, methods of graft fixation as well as any type of graft. Patients considered to be at moderate or high risk of venous thromboembolism should routinely receive thromboprophylaxis after ACL reconstruction. 展开更多

BACKGROUND At present,the preventive treatment for pregnancy-related venous thromboembolism(VTE)in China is in its infancy,and there is no uniform or standardized industry guide.Drug prevention and treatment of pregnancyrelated VTE rely highly on foreign guidelines;however,due to the differences in ethnicity and national conditions,there are many controversies over the indications for drug treatment,drug selection,and dose selection for anticoagulant therapy.AIM To investigate the risk scores,prevention,and treatment of maternal VTE to promote the prevention and standardized treatment of maternal thrombosis.METHODS A retrospective analysis was performed on 7759 patients who gave birth at our hospital from June 2018 to June 2019.Risk factors for pregnancy-related VTE,prenatal and postpartum VTE risk scores,prophylactic anticoagulant therapy,side effects after medication,and morbidity were analysed.RESULTS The risk factors for VTE were mainly caesarean delivery,obesity,and advanced maternal age.Regarding pregnancy-related VTE risk scores,there were 7520 patients in the low-risk group with a prenatal score<3 points and 239 in the high-risk group with a score≥3,and 44 patients received drug prevention and treatment during pregnancy.There were 4223 patients in the low-risk group with a postpartum score<2 points and 3536 in the high-risk group with a score≥2 points,and 824 patients received drug prevention and treatment for 10 d.Among the patients who did not present with VTE before delivery,we found one case each of pulmonary embolism secondary to lower extremity venous thrombosis,intracranial venous sinus thrombosis,and asymptomatic lower extremity venous thrombosis during the postpartum follow-up.CONCLUSION VTE poses a serious threat to maternal safety,and the society should increase its vigilance against pregnancy-related VTE. 展开更多

Objective To evaluate the efficacy and safety of low molecular weight heparin (LMWH) prophylaxis for venous thromboembolism (VTE) after lumbar decompression surgery. Methods Patients at high or the highest risk of VTE who underwent lumbar spine surgery in Peking Union Medical College Hospital from January 2004 to April 2011 were included in the present study. All the patients received a half dose of LMWH 6 hours after surgery followed by a full dose LMWH once per day until discharge. We recorded incidences of deep venous thrombosis (DVT), pulmonary embolism (PE), bleeding complications, and medication side effects. Results Seventy-eight consecutive patients were eligible and enrolled in this study. The mean hospital stat was 8.5±4.5 days. No symptomatic DVT, PE, or major bleeding events were observed. One patient developed wound ecchymosis, another developed wound bleeding, four had mild hepatic aminotransferase level elevation, and one developed a suspicious allergic reaction. Conclusion LMWH may be applied as an effective and safe prophylaxis for VTE in high-risk patients undergoing lumbar decompression surgery. 展开更多
