Patients with Budd-Chiari syndrome (BCS) may require treatment with portal decompressive surgery or liver transplantation. Transjugular intrahepatic portosystemic shunt (TIPS) represents a new treatment alternative, but its long-term effect on BCS outcome has not been evaluated. Twenty-one patients with BCS consecutively admitted to our unit were evaluated. The mean follow-up was 4 +/- 3 years. Seven patients had nonprogressive forms and were successfully controlled with medical therapy; 1 case, with a short-length hepatic vein stenosis was successfully treated by angioplasty. All 8 patients are alive and asymptomatic. The remaining 13 patients, had a TIPS because of clinical deterioration (in one of them, because early TIPS thrombosis a successful side-to-side portacaval shunt [SSPCS] was performed) followed by an improvement in clinical condition. However, a patient with fulminant liver failure before TIPS insertion, died 4 months later and another patient with cirrhosis at diagnosis had liver transplantation 2 years later. The remaining 11 patients are alive and free of ascites. In 3 of these patients TIPS is patent after 3, 6, and 12 months. The remaining 8 patients developed late TIPS dysfunction. In two of these cases, after angioplasty and restenting, TIPS is patent after a follow-up of 9 and 80 months. In 5 other patients, recurring TIPS occlusion was not further corrected because no signs of portal hypertension were present. In conclusion, in patients with BCS uncontrolled with medical therapy, TIPS is a highly effective technique that is associated with long-term survival.
