ABSTRACT
Objective :To observe clinical effect of Viatorr stents in TIPS for treatment of portal hypertension. Methods Thirty-four portal hypertension patients who underwent TIPS using Viatorr stents were collected. The portal vein pressure, the incidence of hepatic encephalopathy and patency rate of shunt were analyzed. Results TIPS was successfully performed using Viatorr stent, the technical success rate was 100%. The preoperative and postoperative portal pressures were (40.00±3.85)cmH2O and (23.60±2.87)cmH2O, respectively. During 1 to 14 months' follow-up, the patency rate of shunt was 100% (34/34), and the incidence of hepatic encephalopathy was 5.88% (2/34). Conclusion :Viatorr TIPS for treatment of portal hypertension has high operative success rate, high shunt patency rate and low incidence of hepatic encephalopathy.
