Graft thrombosis rates after endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms vary widely in published series. When thrombosis does occur, it usually involves a single limb and occurs within 3 months of stent-graft insertion. If the entire endoprosthesis is thrombosed, treatment may be challenging because femoro-femoral crossover graft insertion is not an option and a greater volume of thrombus is present, thus making thrombolysis more difficult. We present two cases of delayed thrombosis after EVAR involving the entire stent-graft. These were successfully treated by a combined surgical and endovascular technique, and patency has been maintained in both cases to date.
血管内动脉瘤修复术（EVAR）治疗腹主动脉瘤后移植物血栓形成的发生率在已发表的系列研究中差异很大。当血栓形成确实发生时，通常涉及单个肢体，并且发生在支架移植物插入后 3 个月内。如果整个内假体发生血栓形成，治疗可能具有挑战性，因为股-股转流移植术不是一种选择，并且存在更大体积的血栓，因此溶栓更为困难。我们报告了两例 EVAR 后整个支架移植物发生延迟性血栓形成的病例。这些病例均通过联合手术和血管内技术成功治疗，并且到目前为止，两种情况下的通畅性均得以维持。
