Isolated iliac artery aneurysm in association with congenital pelvic kidney treated with iliac branch device: case report

Abstract

Background Association of abdominal aortic aneurysm with congenital pelvic kidney is rare and association with isolated iliac artery aneurysm is not yet described in the literature. Case presentation We present a case of successful repair of an isolated common iliac artery aneurysm associated with a congenital pelvic kidney treated by an endovascular technique. A 75-year-old man was referred for the treatment of an asymptomatic left common iliac artery aneurysm. A computed tomography angiography revealed an isolated left common iliac artery aneurysm and a left pelvic kidney. The maximum diameter of the aneurysm was 32 mm. The congenital pelvic kidney was supplied by three small superior polar arteries that emerged from the proximal non-aneurysmal portion of the common iliac artery and the main artery that arose from the left internal iliac artery. The aneurysm exclusion was accomplished by using an iliac branch device (Gore Excluder Iliac Branch, Flagstaff, AZ). The 1 and 6 months computed tomography angiography after the procedure demonstrated complete exclusion of the aneurysm and preservation of all renal arteries. Conclusion Treating patients with an association of iliac artery aneurysms and pelvic kidneys can be a challenge due the variable arterial anatomy. The use of iliac branch device is a safe and effective alternative in selected cases.

“…In two other cases endovascular surgery was chosen to treat AAA with CSPK. In one case the patency of the renal artery was ensured by the chimney technique and in another by Iliac Branch Device [ 9 , 10 ].…”

Endovascular Repair of an Inflammatory Abdominal Aortic Aneurysm Combined with a Congenital Pelvic Kidney: Case Report and Literature Review

“…The remaining five are the lumbar, abdominal, cephalad, thoracic, and crossed ectopia. 5 Fusion phenomena may take place between two ectopic pelvic kidneys forming a solitary congenital fused pelvic kidney (CFPK, the so-called “cake” kidney). 6 CPK and CFPK are associated with aberrant arterial supply originating from different levels of the aorta, the bifurcation, and the iliac arteries.…”
