Abstract

Complete removal of an aortic endograft with suprarenal fixation is difficult. We report the use of a simple device to extract a Zenith endograft. This device is made by cutting off the tip of the cylinder of a 20-mL syringe and rounding off the edges. The main body of the graft is resheathed by advancing the cylinder cranially while keeping the graft in a stable position. This way, the graft collapses and the hooks are withdrawn without tearing the wall of the aorta. The supraceliac clamping time in our patient was less than 2 minutes. This technique offers a safe and fast solution to the potentially hazardous removal of an aortic endograft with suprarenal fixation.

摘要

完全移除带有肾上固定的主动脉内移植物很困难。我们报告使用一种简单装置来取出Zenith内移植物。该装置通过将20毫升注射器的圆筒尖端切掉并将边缘修圆制成。在保持移植物处于稳定位置的同时，将圆筒向头侧推进，从而使移植物主体重新套入。通过这种方式，移植物塌陷，钩子退出，而不会撕裂主动脉壁。我们患者的腹主动脉上段夹闭时间不到2分钟。这项技术为安全、快速地移除带有肾上固定的主动脉内移植物这一潜在危险操作提供了解决方案。
