Summary

Portal vein thrombosis (PVT) refers to an obstruction in the trunk of the portal vein. It can extend downstream to the portal branches, or upstream to the splenic and/or the mesenteric veins. The prevalence of PVT is 10-25% and incidence is about 16% in cirrhotic patients. Recent studies demonstrate that the presence of PVT is not only an independent predictor of failure to control active variceal bleeding and prevent variceal rebleeding, but also significantly associated with increased mortality in patients with liver cirrhosis.

However, in recent American Association of the Study of Liver Disease (AASLD) practice guidelines and Baveno V consensus, no treatment strategies in cirrhotic patients with PVT was clearly recommended due to the absence of randomized controlled trials.

Conditions

  • Decompensated Cirrhosis
  • Portal Vein Thrombosis
  • Bleeding Varices

Interventions

PROCEDURE

Transjugular intrahepatic portosystemic shunt (TIPS)

Transjugular intrahepatic portosystemic shunt(TIPS)- TIPS was performed in a conventional fashion or in combination of percutaneous transhepatic or transsplenic approach. Postoperatively, intravenous heparin (8,000-12,000 u/d) for five days, warfarin for six months were given.

PROCEDURE

ET+NSBB

ET-Esophageal varices was treated by endoscopic variceal ligation (EVL). EVL was repeated at intervals of 1-2 weeks until the varices were obliterated or reduced to grade-I size. NSBB-Propranolol started at a dose of 20mg twice a day. The dose is adjusted to the maximal tolerated doses to heart rate (HR) of 55 bpm or to decrease the HR 25% from baseline. AT-A continuously intravenous infusion of unfractionated heparin followed by oral warfarin is employed. Initially, heparin is administered intravenously for 5 days. Subsequently, oral warfarin is prescribed at the dosage of 2.5 mg/d for 6 months or until complete portal vein recanalization and adjusted to maintain the INR at a target of 2.5 (range 2.0-3.0).
