The role of the transjugular intrahepatic portal-systemic shunt in the management of variceal bleeding

Complications following transjugular intrahepatic portosystemic shunt: a retrospective analysis

Transjugular intrahepatic portosystemic shunt (TIPS) has been the therapeutic option for severe decompensation of chronic liver disease and as a bridge to liver transplantation. The aim of this study was to analyze the complications of this procedure. The records of 47 patients (39 men) of mean age 48 years underwent TIPS procedures from 1998 to 2003 were reviewed. Forty-one patients received 45 successful TIPS; it failed in six patients. Improvement was observed in 20 of 28 patients with upper gastrointestinal bleeding (71%); 9 of 11 with ascites (82%); and 5 of 8 with impaired renal function (62%). The Child-Pugh scores improved in 6 of the 47 patients (13%). Transplantation was performed in 11 patients (23%). The complications were: encephalopathy (49%); infection (19%); renal failure (17%); TIPS migration to the portal vein (4%) and to the right atrium (4%). Mortality was 32% (15/47) over 3 months. Eight patients developed active bleeding during TIPS installation requiring mechanical ventilation and intensive care, and died within the first week. Other causes of death were sepsis (n = 2), liver failure (n = 1), accidental puncture of the Glisson's capsule leading to intra-abdominal bleeding (n = 1) and refractory upper gastrointestinal bleeding (n = 3). The latter four patients had TIPS placement failure. In conclusion, TIPS produced clinical improvement among 51% of patients with complications in 49%. The main complications were encephalopathy (49%), infection (19%), and renal failure (17%). The 3-month mortality rate after TIPS placement was 32%.

[TIPS - Transjugular intrahepatic portosystemic shunt. A review]

At the present time several therapeutic options are used for the treatment of bleeding esophageal varices in patients with portal hypertension. We will review the main medical publications on transjugular intrahepatic portosystemic shunt (TIPS), a procedure seldom used among us. TIPS works as a portocaval side-to-side shunt and decreases the risk of esophageal bleeding through lowering of the portal system pressure and a decrease of the portal hepatic pressure gradient. TIPS consists in the percutaneous insertion, through the internal jugular vein, of a metallic stent under fluoroscopic control in the hepatic parenchyma creating a true porta caval communication. There are several studies demonstrating the efficacy of TIPS, although only a few of them are randomized and control-matched to allow us to conclude that this procedure is safe, efficient and with a good cost benefit ratio. In this review, we search for the analysis of the TIPS utilization, its techniques, its major indications and complications. TIPS has been used in cases of gastroesophageal bleeding that has failed with pharmacologic or endoscopic treatment in patients Child-Pugh B and C. It can be used also as a bridge for liver transplantation. Others indications for TIPS are uncontrolled ascites, hepatic renal syndrome, and hepatic hydrothorax. The main early complications of TIPS using are related to the insertion site and hepatic encephalopathy and the stent occlusion is the chief late complication.
