[Transjugular intrahepatic portosystemic shunt (TIPS) in the treatment of symptomatic portal hypertension].
BACKGROUND
A transjugular intrahepatic portosystemic shunt (TIPS) is the creation of a percutaneous portosystemic anastomosis which is used as an alternative method of surgical portosystemic shunts and endoscopic treatment in the therapy of complications of portal hypertension. The objective of the present work was to summarize experience with TIPS in 100 patients.


RESULTS
In 1992-1995 the authors treated 100 patients with symptomatic portal hypertension by TIPS. To create the shunt in 84% patients a spiral Z stent was used, in the remainder a Wallstent. In 86% patients the indication for TIPS was haemorrhage associated with portal hypertension and in 14% refractory ascites. TIPS was implemented in 98% patients. The pressure in the portal vela was not reduced on average to 58% of the original value. Haemorrhage was not stopped in one of 7 patients. Haemorrhage from varices reappeared in 7% patients indicated on account of repeated haemorrhage and was always associated with the finding of chronic stenosis of the shunt. The mortality in conjunction with the procedure was 4%, the mortality within 30 days after operation was 8%. Uncontrollable encephalopathy developed in 3% of the patients. Primary patency of the shunt created by the spiral Z stent was 85% after 6 months, after 12 months 72% and thus does not differ from primary patency when Wallstents are used, as reported in the literature.


CONCLUSIONS
TIPS is an effective method to reduce the pressure in the portal vein in portal hypertension. The main limiting factor of the method is stenosis of the shunt due to hyperplasia of the neointima. Stenoses of the shunt can be effectively dilated by percutaneous balloon angioplasty.
