Retrograde (proximal) migration of an abdominal aortic aneurysm endograft is an extremely rare event during endovascular insertion and may lead to occlusion of the bilateral renal arteries and dialysis-dependent renal failure. This case report describes the intraoperative retrograde migration of a bifurcated abdominal aortic endograft during the initial endovascular procedure after deployment of an extender limb graft into the right iliac artery and associated bilateral renal artery occlusion. This was treated with renal artery bypass, and the patient had a favorable outcome.
腹主动脉瘤血管内移植物逆行（近端）迁移是血管内插入过程中极其罕见的事件，可能导致双侧肾动脉闭塞和依赖透析的肾衰竭。本病例报告描述了在将延伸支移植物植入右侧髂动脉后首次血管内手术过程中分叉式腹主动脉内移植物的术中逆行迁移，以及由此导致的双侧肾动脉闭塞。采用肾动脉旁路治疗，患者预后良好。
