髂分支支架重建髂内动脉的研究进展

Research progress in reconstruction of internal iliac artery with iliac branch device

摘要:

腹主动脉瘤目前最常见的治疗方式是腹主动脉瘤腔内修复术(EVAR)。然而,当髂总动脉存在扩张或动脉瘤时,支架远端可能会发生内漏现象。在这种情况下,理想的腔内修复应该在完整隔绝动脉瘤的前提下保证盆腔脏器血供。使用髂分支支架(IBD)来保留单侧或双侧髂内动脉是可行且安全的,其技术和临床效果与标准的EVAR手术相当。然而,IBD存在一定的解剖适应性要求。本文就目前应用IBD保存髂内动脉的现状做一系统综述。

Abstract:

Endovascular aneurysm repair (EVAR) is the most common treatment for abdominal aortic aneurysm. However, when the common iliac artery has expansion or aneurysm, there may be internal leakage at the distal end of the stent. In this case, the ideal endovascular repair should ensure the pelvic blood supply on the premise of complete exclusion of the aneurysm. It is feasible and safe to use iliac branch devices (IBD) to preserve unilateral or bilateral internal iliac arteries, and its technology and clinical results are equivalent to standard EVAR. But IBD has certain anatomical adaptability. In this paper, the current status of preservation of internal iliac artery with IBD is systematically reviewed.
