Surgical repair of a very large right common iliac artery aneurysm. Case report and literature review.

AIM: Concomitant abdominal aortic and common iliac artery aneurysms occur in 40% of cases. However, giant common iliac artery aneurysms were rarely described in the current literature. The aim of the present study is to describe the successful treatment of a giant right common iliac artery aneurysm associated with infrarenal abdominal aortic aneurysm. MATERIAL OF STUDY: Wepresent a case of aorto-iliac aneurysm, with giant right common iliac artery aneurysm, responsible of bladder and right psoas muscle compression. Through a midline laparotomy, an aortobisiliac prosthetic repair was performed, associated with prosthetic revascularization of the right internal iliac artery and inferior mesenteric artery. RESULTS: Postoperative recovery was uncomplicated and the patient was discharged on postoperative day 7 in good health and has remained so up to the most recent 12-month follow-up. DISCUSSION: Giant common IA aneurysms represent a very rare pathology, more often associated with infrarenal abdominal aortic aneurysm. After clinical examination, ultrasonography represents the first imaging modality to make diagnosis but CT scan is the gold standard for definitive conclusions, offering accurate anatomical details that are essential to choose the better strategy of treatment. Open surgery represents the gold standard, while endovascular repair has emerged more recently. However results about interventional treatment are not yet described in literature.
