The Viatorr stent-graft (W. L. Gore and Associates), specifically made for transjugular intrahepatic portosystemic shunt (TIPS) creation, has significantly improved TIPS patency compared with bare metal stents. Post-TIPS hepatic encephalopathy (HE), however, remains relatively common after TIPS creation. We describe a technique to secondarily restrict a Viatorr stent-graft to treat post-TIPS refractory HE and maintain use of the Viatorr device.
We show a simple technique to modify the Viatorr stent-graft for TIPS reduction.
Viatorr 支架移植物（戈尔联合公司）专为经颈静脉肝内门体分流术（TIPS）而制造，与裸金属支架相比，显著改善了 TIPS 的通畅性。然而，TIPS 术后肝性脑病（HE）仍然相对常见。我们描述了一种技术，可对 Viatorr 支架移植物进行二次限制，以治疗 TIPS 难治性 HE 并维持 Viatorr 装置的使用。
我们展示了一种用于 TIPS 缩小的简单技术来修改 Viatorr 支架移植物。
