Endovascular management of iliac limb occlusion of bifurcated aortic endografts

Abstract Although aortic endograft iliac limb occlusion is an uncommon event, its treatment is problematic because standard surgical thrombectomy risks graft dislodgment or component separation. Although femorofemoral bypass grafting can restore perfusion to the affected limb, its longevity may be inferior to reestablishing patency of the endograft itself and represents a failure of the endograft procedure. With aortic endografts now commercially available, implanting surgeons must be aware of this important complication and well versed in all of the endovascular treatment options. We report three cases of endoluminal management of unilateral iliac limb occlusion of bifurcated aortic endografts. (J Vasc Surg 2002;35:584-8.)
