The rate of success, complication, mortality of the procedure and postoperative complication were recorded and analyzed.RESULTS: PTSVE were successfully performed in 16 of 18cases, and the rate of success was 89%. After therapy erythrocyte counts decreased in all of the natunts. 5 of patients needed blood transfusion, 2 patients requiredsurgical intervention because of and 11 patients with ascites were alleviated by diuresis. Among these 18patients, the procedure-related mortality was 11% (2/18),one died of acute hepatic failure on the forth day after procedure, another died of acute renal failure on the fifth day. The patients were follow up for 112 mon exceptone. 13of them died of their tumors but none of them experienced variceal bleeding.CONCLUSION: PTSVE is a relatively safe and effective method to treat esophageal or gastrio-fundal varices in HCCpatients with PVCT when percutaneous transhepatic varices embolization (PTHVE) of varices is impossible.展开更多

The surgical therapy of this disease focuses on the re sultant upper digestive tract bleeding, which can imperi patients' life directly. This study was to evaluate the effect of triplex operation ( mesocaval C shunt with artificia graft, ligation of the coronary vein and splenic artery) on portal hypertension and its associated upper digestive tract bleeding. METHODS: A retrospective study was made on clinical da- ta of 140 patients undergoing triplex operation, who had suffered from portal hypertension and upper digestive tract bleeding. RESULTS: Postoperative portal pressure was 25-43 cmH2 O ( preoperative portal pressure 27-45 cmH2 O ) with the average reduction of 10 cmH2O. One patient (0.7%) died of cerebrovascular disease. Five patients (3.5%) suffered from mild hepatic encephalopathy, which was ameliorated through conservative treatment. Lymphatic fistula occurred in 3 patients (2.1% ) who recovered without treatment 5, 10 days and 3 months after operation respectively. One hundred patients were followed up for 1 month to 6 years without recurrent hemorrhage or hepatic encephalopathy. Hypersplenism and ascites disappeared in 70 patients (70% ) and 80 patients (80% ) respectively. A significant reduction of ascites was seen in 12 patients(12% ). The arti- ficial vessels remained unblocking detected by B type ultra- sonography and Doppler sonography in 95 patients (95% ). CONCLUSION: Triplex operation is suitable for patients with the following portal hypertensions; portal hyperten- sion caused by simple occlusion of the hepatic vein (a patho- logical type of Budd-Chiari syndrome); thrombosis of the portal vein or prehepatic portal hypertension because of cavernous transformation; intrahepatic portal hypertension with rebleeding after splenectomy or non-operation, and those patients with liver function in grade A or B according to the Child-Pugh classification.展开更多
