OBJECTIVE
To compare the incidence of endograft limb thrombosis in different types of endovascular aortoiliac aneurysm repair.
MATERIAL AND METHODS
We retrospectively analyzed 72 patients with aortoiliac aneurysm divided into 2 groups depending on endovascular procedure and internal iliac artery perfusion. The first group included 31 patients who underwent EVAR without internal iliac artery occlusion. The second group included 41 patients who underwent EVAR with unilateral or bilateral internal iliac artery coverage.
RESULTS
Primary technical success was achieved in all patients. All patients underwent survey and CT-aortography after 1 and 12 months. There were no cases of buttock claudication in the first group. In the second group, this event developed in 6 patients and regressed without intervention in 3 cases. There were 6 cases of endograft limb thrombosis in the second group, all patients underwent open surgery. No thrombosis was noted in the first group. No aneurysm growth or endoleak type Ib/II with need for redo intervention and signs of pelvic ischemia were observed in any patient.
CONCLUSION
Iliac bifurcation device significantly reduces the incidence of endograft limb thrombosis in patients with aortoiliac aneurysm.
