Viatorr覆膜支架在经颈静脉肝内门体分流术中的应用现状

摘要

Transjugular intrahepatic portosystemic shunt (TIPS) has been widely used in the treatment of the complications of portal hypertension,and in recent years,with a deepened understanding of TIPS,covered stents have been further developed and applied in clinical practice,among which a special stent for TIPS,Viatorr covered stent,has become a focus of attention.This article reviews the application and effect of Viatorr stent and points out that Viatorr stent can establish intrahepatic shunt and thus significantly improve shunt patency rate.Meanwhile,it can reduce the risk of repeated intervention and rebleeding without increasing the incidence rate of hepatic encephalopathy and improve patients'quality of life.%经颈静脉肝内门体分流术(TIPS)已广泛应用于治疗门静脉高压并发症,近年来随着对于TIPS认识程度的加深,覆膜支架得到更进一步的发展应用,其中TIPS专用支架(Viatorr覆膜支架)更是成为关注的焦点.综述了Viatorr覆膜支架的应用与效果,指出采用Viatorr覆膜支架建立肝内分流通道能够明显提高分流道通畅率,在未增加肝性脑病的发生率的同时减少了重复干预及再出血的风险,使患者的生活质量得到提高.
