Transjugular intrahepatic portosystemic shunt (TIPS): indications and long-term patency.
BACKGROUND
Since the introduction of TIPS (the transjugular intrahepatic portosystemic shunt) into clinical practice in 1989, substantial knowledge, partially derived from controlled trials, has become available regarding technical and clinical aspects of the procedure. A number of prospective studies have assessed the long-term patency of radiological shunts, the recognized main technical weakness of the procedure.


METHODS
Review of published data regarding the optimal indications and long-term patency of TIPS.


RESULTS
Information on the long-term patency of TIPS is surprisingly scarce. Within 2 years of TIPS creation, re-interventions to re-establish or maintain the patency of the shunt are required in 70%-90% of patients, and in 20%-40% total occlusion develops. Limited available data suggest, however, that in about 80% of patients the shunt is patent after 3-5 years. There is consensus that TIPS is a main, second-line treatment option for variceal haemorrhage not responding to other therapies. Although widely used for treating refractory ascites, gastric variceal bleeding and Budd-Chiari syndrome, these indications require more study. A number of other potential indications remain poorly defined.


CONCLUSIONS
TIPS is a major treatment modality to manage the complications of portal hypertension and Budd-Chiari syndrome. The available data indicate that TIPS is not only a short-term treatment option but may provide long-term portosystemic decompression. Technical improvements, e.g. the use of covered or drug-eluting stents, are essential to reduce the high rate of shunt dysfunction.
