Abstract | BACKGROUND & AIMS: The first studies comparing covered stents (CS) and bare stents (BS) to achieve Transjugular Intrahepatic Portosystemic Shunt ( TIPS) were in favor of CS, but only one randomized study has been performed. Our aim was to compare the primary patency of TIPS performed with CS and BS. METHODS: The study was planned as a multicenter, pragmatic (with centers different in size and experience), randomized, single-blinded (with blinding of patients only), parallel group trial. The primary endpoint was TIPS dysfunction defined as either a portocaval gradient ⩾12mmHg, or a stent lumen stenosis ⩾50%. A transjugular angiography with portosystemic pressure gradient measurement was scheduled every 6months after TIPS insertion. RESULTS: 137 patients were randomized: 66 to receive CS, and 71 BS. Patients who were found to have a hepato-cellular carcinoma, or whose procedure was cancelled were excluded, giving a sample of 129 patients (62 vs. 67). Median follow-up for CS and BS were 23.6 and 21.8months, respectively. Compared to BS, the risk of TIPS dysfunction with CS was 0.60 95% CI [0.38-0.96], (p=0.032). The 2-year rate of shunt dysfunction was 44.0% for CS vs. 63.6% for BS. Early post TIPS complications (22.4% vs. 34.9%), risk of hepatic encephalopathy (0.89 [0.53-1.49]) and 2-year survival (70% vs. 67.5%) did not differ in the two groups. The 2-year cost/patient was 20k€ [15.9-27.5] for CS vs. 23.4k€ [18-37] for BS (p=0.52). CONCLUSIONS: CS provided a significant 39% reduction in dysfunction compared to BS. We did not observe any significant difference with regard to hepatic encephalopathy or death.
