Endovascular therapeutic options for the treatment of aortoiliac aneurysms

ABSTRACT About 20% of patients with abdominal aortic aneurysms have associated iliac aneurysms. Distal sealing during the endovascular treatment of aortic-iliac aneurysms is a challenge that has led to the emergence of several technical options to achieve this goal over the years. Internal iliac artery embolization is associated with the risk of ischemic complications, such as gluteal necrosis, lower limb neurological deficit, colonic ischemia, impotence and gluteal claudication. This article summarizes the technical options for endovascular treatment of aortoiliac aneurysms with different approaches to preserving the patency of internal iliac arteries.

摘要 约20%的腹主动脉瘤（abdominal aortic aneurysm）患者合并髂动脉瘤（iliac aneurysm）。在主动脉髂动脉瘤的血管腔内治疗过程中，远端封闭始终是一项临床难题，多年来为此催生了多种技术方案以达成该治疗目标。髂内动脉栓塞术（internal iliac artery embolization）存在引发缺血性并发症的风险，具体包括臀肌坏死、下肢神经功能缺损、结肠缺血、勃起功能障碍及臀肌跛行。本文综述了采用不同术式保留髂内动脉通畅性的主动脉髂动脉瘤血管腔内治疗技术方案。
