Comparison of Covered and Bare Stent in TIPS

Comparison of Covered and Bare Stent in TIPS

Investigators aim to compare the efficacy of 8 mm Fluency covered stent and bare stent in transjugular intrahepatic portosystemic shunt (TIPS) for the treatment of cirrhotic portal hypertension.

From January 2006 to December 2010, the covered (experimental group) or bare stent (control group) was used in 131 and 127 patients, respectively. The recurrence rates of gastrointestinal bleeding and refractory hydrothorax/ascites, the cumulative restenosis rates in 1, 2, 3, 4, and 5-years, the incidence rate of hepatic encephalopathy, the rate of secondary interventional therapy, the 1, 2, 3, 4 and 5-year survival rates were compared between the experimental group and the control group.

Inclusion Criteria:

1. portal hypertension patients with defined indications for TIPS treatment;
2. scheduled for elective TIPS; and
3. aged between 18-70 years.

Exclusion Criteria:

1. combined with hepatic encephalopathy before the treatment;
2. combined with portal vein thrombosis;
3. combined with malignant liver tumor or malignancies at the other sites; or
4. combined with hemorrhage of gastrointestinal ulcer.
