Experience with endovascular treatment of iliac artery aneurysms

Iliac artery aneurysms are relatively uncommon, however requiring early diagnosis and treatment because of high mortality once ruptured. Endovascular correction is currently a method of choice. The standard iliac components of aortic stent grafts have a linear or distally widening shape, whereas the anatomy of aneurysms of iliac arteries requires, as a rule, a larger diameter of the proximal zone of shrinkage. Optimal is considered to be the use of reversed stent grafts, i. e. those tapering distally. The authors herein share their experience in treating iliac artery aneurysms using a flared reversed endograft of the iliac branch of the Anaconda stent graft in three patients presenting with iliac artery aneurysms. Technical success was achieved in all cases. In the remote period (6-12 months postoperatively) the grafts were patent, with no leakage.
