Recently, balloon-occluded TACE(B-TACE) was developed in Japan. Despite the lack of a clear definition, B-TACE is generally defined as the infusion of emulsion of chemotherapeutic agents with lipiodol followed by gelatin particles under the occlusion of feeding arteries by a microballoon catheter, which leads to the dense lipiodol emulsion(LE) accumulation in HCC nodules. This phenomenon cannot be explained only by the prevention of proximal migration and leakage of embolization materials; it further involves causing local changes in the hemodynamics of the surrounding occlusion artery and targeted HCC nodules. Balloon-occluded arterial stump pressure plays an important role in the dense LE accumulation in targeted HCC nodules. Although randomized controlled trials comparing the therapeutic effect and the prognosis of B-TACE to those of the other TACE procedures, such as conventional-TACE and drug-eluting beads TACE, are still lacking, B-TACE is thought to be a promising treatment. The purpose of this review is to summarize the mechanism, therapeutic effect, indication, prognosis and complications of BTACE.展开更多

Of the 93 patients, 75 were treated with the balloon-occluded retrograde transvenous obliteration (BRTO) procedure; 8 were with the percutaneous transhepatic obliteration (PTO) procedure; and 10 were with the combined BRTO and PTO therapy. A follow-up evaluation examined the rates of survival, recurrence and rebleeding of the gastric varices, worsening of esophageal varices and complications in each group. RESULTS: The BRTO, PTO, and combined therapy were technically successful in 81% (75/93), 44% (8/18), and 100% (10/10) patients, respectively. Recurrence of gastric varices was found in 3 patients in the BRTO group and in 3 patients in the PTO group. Rebleeding was observed in 1 patient in the BRTO group and in 1 patient in the PTO group. The 1- and 3-year survival rates were 98% and 87% in the patients without hepatocellular carcinoma (HCC) in the BRTO group, 100% and 100% in the PTO group, and 90% and 75% in the combined therapy group, respectively. CONCLUSION: Combined BRTO and PTO therapy may rescue cases with uncontrollable gastric fundal varices that remained even after treatment with BRTO and/or PTO, though there were limitations of our study, including retrospective nature and discrepancy in sample size between the BRTO, PTO and combined therapy groups.展开更多

Contrast-enhanced CT revealed gastric varices and hepatocellular carcinoma with tumor thrombi in the right portal vein. Angiography and angio-CT revealed a marked intratumoral arterioportal shunt accompanied with reflux into the main portal vein and gastric varices. Balloon-occluded retrograde venography from the gastro-renal shunt showed no visualization of gastric varices due to rapid blood flow through the intratumoral arterioportal shunt. The hepatic artery was temporarily occluded with a balloon catheter to reduce the blood flow through the arterioportal shunt, and then concurrent balloon-occluded retrograde transvenous obliteration (BRTO) was achieved. Vital signs stabilized immediately thereafter, and contrast-enhanced CT revealed thrombosed gastric varices. Worsening of hepatic function was not recognized. BRTO combined with temporary occlusion of the hepatic artery is a feasible interventional procedure for ruptured high flow gastric varices with an intratumoral arterioportal shunt.展开更多

One week later, contrast-enhanced CT revealed extensive portal vein thrombosis (PVT) and dilated portosystemic shunts. The PVT was not dissolved by the intravenous administration of urokinase. The right portal vein was canulated via the percutaneous transhepatic route under ultrasonic guidance and a 4 Fr. straight catheter was advanced into the portal vein through the thrombus. Transhepatic catheter-directed thrombolysis was performed to dissolve the PVT and a splenorenal shunt was concurrently occluded to increase portal blood flow, using balloon-occluded retrograde transvenous obliteration (BRTO) technique. Subsequent contrast-enhanced CT showed good patency of the portal vein and thrombosed splenorenal shunt. Transhepatic catheter-directed thrombolysis combined with BRTO is feasible and effective for PVT with portosystemic shunts.展开更多

Ectopic colonic varices development from liver cirrhosis and portal hypertension is uncommon. They are part of the spectrum of portal hypertensive colopathy. Colonic variceal bleeding remains a rare cause of lower gas...Ectopic colonic varices development from liver cirrhosis and portal hypertension is uncommon. They are part of the spectrum of portal hypertensive colopathy. Colonic variceal bleeding remains a rare cause of lower gastrointestinal tract (GI) bleeding. Due to the paucity of cases, there are no well-established conventional treatments for bleeding colonic varices. Different treatments have been reported. Here, we report a case of a 55-year-old gentleman, with a history of alcoholic liver cirrhosis, presenting with severe lower GI bleeding and symptomatic anaemia. An esophagogastroduodenoscopy revealed large esophageal varices with high-risk bleeding stigmata requiring endoscopic variceal ligation. A cross-sectional computed tomography scan showed colonic portosystemic shunts. In light of this and that the severe lower GI bleeding seemed out of proportion to the esophageal varices seen on upper endoscopy, an urgent unprepped colonoscopy was performed which revealed possible bleeding diverticula disease which required endoscopic mechanical hemoclip therapy. However, despite this, patient had recurrence of lower GI bleeding prompting a second colonoscopy. This relook colonoscopy showed ectopic ascending colon varices with high-risk bleeding stigmata. High-dose intravenous vasoactive agent somatostatin (500 mcg/hour) and subsequently terlipressin (2 mg every 4 hours) were used. The patient subsequently underwent successful balloon-occluded retrograde transvenous obliteration (B-RTO) and sclerotherapy. The non-selective beta-blocker (NSBB) carvedilol was started and bridged together with the vasoactive agent until stabilisation of portal hypertension. This difficult case illustrates the dynamic nature of portal hypertensive bleeding. It also highlights the presence of confounding non-variceal pathology complicating diagnosis of portal hypertensive colonic variceal bleeding, and that ectopic ascending colonic variceal bleeding can be treated successfully with B-RTO and sclerotherapy, with meticulous titration of high-dose vasoactive agents and NSBB, in a decompensated alcoholic liver cirrhosis patient.展开更多

文摘BACKGROUND Hyperammonemia and hepatic encephalopathy are common in patients with portosystemic shunts.Surgical shunt occlusion has been standard treatment,although recently the less invasive balloon-occluded retrograde transvenous obliteration(B-RTO)has gained increasing attention.Thus far,there have been no reports on the treatment of portosystemic shunts with B-RTO in patients aged over 90 years.In this study,we present a case of hepatic encephalopathy caused by shunting of the left common iliac and inferior mesenteric veins,successfully treated with B-RTO.CASE SUMMARY A 97-year-old woman with no history of liver disease was admitted to our hospital because of disturbance of consciousness.She had no jaundice,spider angioma,palmar erythema,hepatosplenomegaly,or asterixis.Her blood tests showed hyperammonemia,and abdominal contrast-enhanced computed tomography revealed a portosystemic shunt running between the left common iliac vein and the inferior mesenteric vein.She was diagnosed with hepatic encephalopathy secondary to a portosystemic shunt.The patient did not improve with conservative treatment:Lactulose,rifaximin,and a low-protein diet.B-RTO was performed,which resulted in shunt closure and improvement in hyperammonemia and disturbance of consciousness.Moreover,there was no abdominal pain or elevated levels of liver enzymes due to complications.The patient was discharged without further consciousness disturbance.CONCLUSION Portosystemic shunt-borne hepatic encephalopathy must be considered in the differential diagnosis for consciousness disturbance,including abnormal behavior and speech.

文摘Transcatheter arterial chemoembolization(TACE) is widely accepted as a treatment for patients with hepatocellular carcinoma(HCC) in the intermediate stage according to the Barcelona Clinic Liver Cancer(BCLC) guidelines.

文摘AIM: To evaluate the effect of three interventional treatments involving transvenous obliteration for the treatment of gastric varices, and to compare the efficacy and adverse effects of these methods, METHODS: From 1995 to 2004, 93 patients with gastric fundal varices underwent interventional radiologic embolotherapy at our hospital. Of the 93 patients, 75 were treated with the balloon-occluded retrograde transvenous obliteration (BRTO) procedure; 8 were with the percutaneous transhepatic obliteration (PTO) procedure; and 10 were with the combined BRTO and PTO therapy. A follow-up evaluation examined the rates of survival, recurrence and rebleeding of the gastric varices, worsening of esophageal varices and complications in each group. RESULTS: The BRTO, PTO, and combined therapy were technically successful in 81% (75/93), 44% (8/18), and 100% (10/10) patients, respectively. Recurrence of gastric varices was found in 3 patients in the BRTO group and in 3 patients in the PTO group. Rebleeding was observed in 1 patient in the BRTO group and in 1 patient in the PTO group. The 1- and 3-year survival rates were 98% and 87% in the patients without hepatocellular carcinoma (HCC) in the BRTO group, 100% and 100% in the PTO group, and 90% and 75% in the combined therapy group, respectively. CONCLUSION: Combined BRTO and PTO therapy may rescue cases with uncontrollable gastric fundal varices that remained even after treatment with BRTO and/or PTO, though there were limitations of our study, including retrospective nature and discrepancy in sample size between the BRTO, PTO and combined therapy groups.
文摘A patient presented with hematemesis due to gastric variceal bleeding with an intratumoral arterioportal shunt. Contrast-enhanced CT revealed gastric varices and hepatocellular carcinoma with tumor thrombi in the right portal vein. Angiography and angio-CT revealed a marked intratumoral arterioportal shunt accompanied with reflux into the main portal vein and gastric varices. Balloon-occluded retrograde venography from the gastro-renal shunt showed no visualization of gastric varices due to rapid blood flow through the intratumoral arterioportal shunt. The hepatic artery was temporarily occluded with a balloon catheter to reduce the blood flow through the arterioportal shunt, and then concurrent balloon-occluded retrograde transvenous obliteration (BRTO) was achieved. Vital signs stabilized immediately thereafter, and contrast-enhanced CT revealed thrombosed gastric varices. Worsening of hepatic function was not recognized. BRTO combined with temporary occlusion of the hepatic artery is a feasible interventional procedure for ruptured high flow gastric varices with an intratumoral arterioportal shunt.
文摘Rupture of gastric varices(GVs)can be fatal.Balloon-occluded retrograde transvenous obliteration(BRTO),as known as retrograde sclerotherapy,has been widely adopted for treatment of GVs because of its effectiveness,ability to cure,and utility in emergency and prophylactic treatment.Simplifying the route of blood flow from GVs to the gastrorenal shunt is important for the successful BRTO.This review outlines BRTO indications and contraindications,describes basic BRTO procedures and modifications,compares BRTO with other GVs treatments,and discusses various combination therapies.Combined BRTO and partial splenic embolization may prevent exacerbation of esophageal varices and shows promise as a treatment option.
文摘A 66-year-old woman underwent partial splenic embolization (PSE) for hypersplenisrn with idiopathic portal hypertension (IPH). One week later, contrast-enhanced CT revealed extensive portal vein thrombosis (PVT) and dilated portosystemic shunts. The PVT was not dissolved by the intravenous administration of urokinase. The right portal vein was canulated via the percutaneous transhepatic route under ultrasonic guidance and a 4 Fr. straight catheter was advanced into the portal vein through the thrombus. Transhepatic catheter-directed thrombolysis was performed to dissolve the PVT and a splenorenal shunt was concurrently occluded to increase portal blood flow, using balloon-occluded retrograde transvenous obliteration (BRTO) technique. Subsequent contrast-enhanced CT showed good patency of the portal vein and thrombosed splenorenal shunt. Transhepatic catheter-directed thrombolysis combined with BRTO is feasible and effective for PVT with portosystemic shunts.
文摘A 76-year-old woman with hepatitis C cirrhosis presented with tarry stools and hematemesis.An endoscopy demonstrated bleeding duodenal varices in the second portion of the duodenum.Contrast-enhanced computed tomography revealed markedly tortuous varices around the wall in the duodenum.Several afferent veins appeared to have developed,and the right ovarian vein draining into the inferior vena cava was detected as an efferent vein.Balloon-occluded retrograde transvenous obliteration (BRTO) of the varices using cyanoacrylate was successfully performed in combination with the temporary occlusion of the portal vein.Although no previous publications have used cyanoacrylate as an embolic agent for BRTO to control bleeding duodenal varices,this strategy can be considered as an alternative procedure to conventional BRTO using ethanolamine oleate when numerous afferent vessels that cannot be embolized are present.
文摘AIM: To evaluate the effectiveness and safety of emergency balloon-occluded retrograde transvenous obliteration(BRTO) for ruptured gastric varices.METHODS: Emergency BRTO was performed in 17 patients with gastric varices and gastrorenal or gastrocaval shunts within 24 h of hematemesis and/or tarry stool.The gastric varices were confirmed by endoscopy,and the gastrorenal or gastrocaval shunts were identified by contrast-enhanced computed tomography(CE-CT).A 6-Fr balloon catheter(Cobra type) was inserted into the gastrorenal shunt via the right internal jugular vein,or into the gastrocaval shunt via the right femoral vein,depending on the varices drainage route.The sclerosant,5% ethanolamine oleate iopamidol,was injected into the gastric varices through the catheter during balloon occlusion.In patients with incom plete thrombosis of the varices after the first BRTO,a second BRTO was performed the following day.Patients were followed up by endoscopy and CE-CT at 1 d,1 wk,and 1,3 and 6 mo after the procedure,and every 6 mo thereafter.RESULTS: Complete thrombosis of the gastric varices was not achieved with the first BRTO in 7/17 patients because of large gastric varices.These patients underwent a second BRTO on the next day,and additional sclerosant was injected through the catheter.Complete thrombosis which led to disappearance of the varices was achieved in 16/17 patients,while the remaining patient had incomplete thrombosis of the varices.None of the patients experienced rebleeding or recurrence of the gastric varices after a median follow-up of 1130 d(range 8-2739 d).No major complications occurred after the procedure.However,esophageal varices worsened in 5/17 patients after a mean follow-up of 8.6 mo.CONCLUSION: Emergency BRTO is an effective and safe treatment for ruptured gastric varices.
文摘Gastric varices are usually associated with a gastrorenal(G-R) shunt.However,the gastric varices described in this case report were not associated with a G-R shunt.The inflow vessel was the posterior gastric vein and the outflow vessels were the narrow inferior phrenic vein and the dilated cardio-phrenic vein.First,percutaneous transhepatic obliteration of the posterior gastric vein was performed,but the gastric varices remained patent.Then,micro-balloon catheterization of the subphrenic vein was carried out via the jugular vein,pericardial vein and cardio-phrenic vein,however,micro-balloon-occluded inferior phrenic venography followed by micro-coil embolization of the cardio-phrenic vein revealed no delineation of gastric varices resulting in no further treatment.Thereafter,as a gastrosubphrenic-intercostal vein shunt developed,a microballoon catheter was advanced to the gastric varices via the intercostal vein and balloon-occluded retrograde transvenous obliteration(BRTO) was performed resulting in the eradication of gastric varices.BRTO for gastric varices via the intercostal vein has not previously been documented.

文摘Objectives:To evaluate the safety and efficacy of balloon-occluded retrograde transvenous obliteration(BRTO)using lauromacrogol sclerosant foam for gastric varices(GVs)with gastrorenal venous shunts.Methods:Data of GV patients treated with BRTO using lauromacrogol sclerosant foam in 2016–2020 were retrospectively analyzed along with procedural success rate,complications,and follow-up efficacy.Results:A total of 31 patients were treated with BRTO.The sclerosant foam was prepared by mixing iodinated oil,lauromacrogol,and air at a 1:2:3 ratio.The BRTO procedure was successfully completed in 93.5%of patients.One patient was allergic to the lauromacrogol injection.A mild postoperative fever occurred in three patients.One patient experienced grand mal seizures after the procedure.There was no significant difference in the median Child-Turcotte-Pugh scores before versus after BRTO.Complete GV resolution was observed in 93.1%of patients.One patient underwent endoscopic treatment for the development of high-risk esophageal varices.Another patient underwent transjugular intrahepatic portosystemic shunt placement for the aggravation of ascites.Conclusions:Lauromacrogol sclerosant foam is safe and effective in patients undergoing BRTO for GV.
文摘Ectopic colonic varices development from liver cirrhosis and portal hypertension is uncommon. They are part of the spectrum of portal hypertensive colopathy. Colonic variceal bleeding remains a rare cause of lower gastrointestinal tract (GI) bleeding. Due to the paucity of cases, there are no well-established conventional treatments for bleeding colonic varices. Different treatments have been reported. Here, we report a case of a 55-year-old gentleman, with a history of alcoholic liver cirrhosis, presenting with severe lower GI bleeding and symptomatic anaemia. An esophagogastroduodenoscopy revealed large esophageal varices with high-risk bleeding stigmata requiring endoscopic variceal ligation. A cross-sectional computed tomography scan showed colonic portosystemic shunts. In light of this and that the severe lower GI bleeding seemed out of proportion to the esophageal varices seen on upper endoscopy, an urgent unprepped colonoscopy was performed which revealed possible bleeding diverticula disease which required endoscopic mechanical hemoclip therapy. However, despite this, patient had recurrence of lower GI bleeding prompting a second colonoscopy. This relook colonoscopy showed ectopic ascending colon varices with high-risk bleeding stigmata. High-dose intravenous vasoactive agent somatostatin (500 mcg/hour) and subsequently terlipressin (2 mg every 4 hours) were used. The patient subsequently underwent successful balloon-occluded retrograde transvenous obliteration (B-RTO) and sclerotherapy. The non-selective beta-blocker (NSBB) carvedilol was started and bridged together with the vasoactive agent until stabilisation of portal hypertension. This difficult case illustrates the dynamic nature of portal hypertensive bleeding. It also highlights the presence of confounding non-variceal pathology complicating diagnosis of portal hypertensive colonic variceal bleeding, and that ectopic ascending colonic variceal bleeding can be treated successfully with B-RTO and sclerotherapy, with meticulous titration of high-dose vasoactive agents and NSBB, in a decompensated alcoholic liver cirrhosis patient.
文摘AIM:To evaluate whether intra-procedural conebeam computed tomography(CBCT)performed during modified balloon-occluded retrograde transvenous obliteration(mB RTO)can accurately determine technical success of complete variceal obliteration.METHODS:From June 2012 to December 2014,15 patients who received CBCT during m BRTO for treatment of portal hypertensive gastric variceal bleeding were retrospectively evaluated.Three-dimensional(3D)CBCT images were performed and evaluated prior to the end of the procedure,and these were further analyzed and compared to the pre-procedure contrast-enhanced computed tomography to determine the technical success of m BRTO including:Complete occlusion/obliteration of:(1)gastrorenal shunt(GRS);(2)gastric varices;and(3)afferent feeding veins.Post-mB RTO contrast-enhanced CT was used to confirm the accuracy and diagnostic value of CBCT within 2-3 d.RESULTS:Intra-procedural 3D-CBCT images were 100% accurate in determining the technical success of m BRTO in all 15 cases.CBCT demonstrated complete occlusion/obliteration of GRS,gastric varices,collaterals and afferent feeding veins during m BRTO,which was confirmed with post-m BRTO CT.Two patients showed incomplete obliteration of gastric varices and feeding veins on CBCT,which therefore required additional gelfoam injections to complete the procedure.No patient required additional procedures or other interventions during their follow-up period(684 ± 279 d).CONCLUSION:CBCT during mB RTO appears to accurately and immediately determine the technical success of mB RTO.This may improve the technical and clinical success/outcome of m BRTO and reduce additional procedure time in the future.
