OBJECTIVE
Transjugular intrahepatic portosystemic shunt (TIPS) creation increases the risk of hepatic encephalopathy due to overshunting. Techniques exist to secondarily reduce the shunt for refractory encephalopathy. The purpose of this article is to describe a technique for primary TIPS restriction using a balloon-expandable stent within the transvenous hepatic track followed by deployment of a self-expanding polytetrafluoroethylene-lined stent-graft within the balloon-expandable stent to create the TIPS.
CONCLUSION
This technique enables control over the degree of portosystemic shunting in elective TIPS creation.
目的
经颈静脉肝内门体分流术（TIPS）由于分流过度会增加肝性脑病的风险。对于难治性脑病，存在一些可二次减少分流的技术。本文的目的是描述一种在经静脉肝内通道内使用球囊扩张支架进行原发性TIPS限流的技术，随后在球囊扩张支架内植入自膨式聚四氟乙烯内衬覆膜支架以建立TIPS。
结论
该技术能够在择期TIPS建立过程中控制门体分流的程度。
