Basing on our experience with three dislocated or displaced stents (one Wallstent, two Plamaz stents) during or after TIPS-procedure, we describe our technique to reposition or remove the stents.
The stents were moved back into the inferior vena cava by means of a balloon catheter, an alligator forceps, or an Amplatz gooseneck snare. They were secured against further dislocation by a central guidewire. After insertion of a balloon catheter into each dislocated stent, they were coaxially grasped with an Amplatz gooseneck snare. Stent diameter was reduced by forceful closure of the snare, and then the stent was either relocated or removed.
To prevent further stent migration it is necessary to remove the stent via a guidewire. By using a balloon catheter and a coaxially inserted Amplatz gooseneck snare, reduction of the outer stent diameter is possible even in Plamaz stents, facilitating their relocation or removal.
基于我们在经颈静脉肝内门体分流术（TIPS）过程中或术后处理3例脱位或移位支架（1例Wallstent支架，2例Plamaz支架）的经验，我们描述重新定位或取出支架的技术。
通过球囊导管、鳄齿钳或Amplatz鹅颈圈套器将支架移回下腔静脉。用中心导丝固定以防进一步脱位。将球囊导管插入每个脱位的支架后，用Amplatz鹅颈圈套器同轴抓取。通过强力收紧圈套器减小支架直径，然后将支架重新定位或取出。
为防止支架进一步移位，有必要通过导丝取出支架。通过使用球囊导管和同轴插入的Amplatz鹅颈圈套器，即使是Plamaz支架也可以减小其外部直径，便于重新定位或取出。
