Transjugular intrahepatic portosystemic shunts in the treatment of refractory ascites: results in 48 consecutive patients.

摘要

PURPOSE: To assess the efficacy, morbidity, and mortality involved in the creation of transjugular intrahepatic portosystemic shunts (TIPS) in the treatment of patients with refractory ascites in Child-Pugh classes B and C. MATERIALS AND METHODS: Forty-eight consecutive patients with refractory ascites were treated with TIPS creation in a tertiary care institution. They were followed for a median of 337 days (range, 3-1376 d). RESULTS: TIPS significantly decreased the portohepatic pressure gradient (20.7 +/- 5.9 mm Hg vs. 6.8 +/- 4.1 mm Hg; P < .0001). Seventy-three percent of patients had complete or partial response. One year after TIPS creation, survival was 73% in Child class B patients and 56% in Child class C patients. Thirteen patients experienced procedural complications (portal vein thrombosis, peritoneal bleeding, acute renal failure, pneumothorax, hemoptysis, spontaneous bacterial peritonitis, and heart failure) and TIPS creation was considered the cause of death in five patients (10.4%). Primary patency was 65% at 3 months and 23% at 1 year, but shunt obstruction was accessible for a second intervention. Ten patients (21%) had de novo encephalopathy after TIPS creation. CONCLUSIONS: This series suggests that TIPS is an effective treatment for refractory ascites; however, it is a challenging procedure and serious complications--usually renal and heart failure--can be seen. A careful selection of patients is mandatory.
