Introduction: Reconstructing the internal iliac artery (IIA) may help to prevent pelvic ischemia during open repair of abdominal aortic aneurysms (AAAs) with iliac arterial lesions. Composite grafts combined with Y-shaped and straight vascular grafts have previously been used to reconstruct the IIA. However, multifurcated vascular grafts have recently been used to treat AAAs with iliac arterial lesions. We, therefore, assessed the viability of multifurcated vascular grafts for AAAs with iliac arterial lesions. Materials and Methods: We retrospectively reviewed 87 patients who underwent elective open repair with reconstruction of IIAs under infrarenal clamp for AAAs with iliac arterial lesions between April 2002 and August 2015. Forty-three patients received multifurcated vascular grafts including 23 patients who underwent reconstructed unilateral IIA, and 44 patients received composite grafts including forty patients with reconstructed unilateral IIA. We compared the multifurcated and composite graft groups among all patients and also compared among patients who underwent unilateral IIA reconstruction. Results: There were no significant differences between the two groups among all patients in terms of intra- and post-operative data. There were no cases of hospital death or buttock claudication. In propensity score matching analysis among patients with unilateral IIA reconstruction, 22 patients were extracted each group. There were no significant differences in any preoperative or perioperative parameters between the groups. Conclusions: We could not show the availability of open repair using multifurcated vascular grafts for AAA with iliac arterial lesions with comparable results compared to composite grafts.
