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 inthe current literature. The aim of the present study is to describe thesuccessful treatment of a giant right common iliac artery aneurysm associatedwith infrarenal abdominal aortic aneurysm.MATERIAL OF STUDY: We present a case of aorto-iliac aneurysm, with giant rightcommon iliac artery aneurysm, responsible of bladder and right psoas musclecompression. Through a midline laparotomy, an aortobisiliac prosthetic repair wasperformed, associated with prosthetic revascularization of the right internaliliac 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 recent12-month follow-up.DISCUSSION: Giant common IA aneurysms represent a very rare pathology, more oftenassociated with infrarenal abdominal aortic aneurysm. After clinical examination,ultrasonography represents the first imaging modality to make diagnosis but CTscan is the gold standard for definitive conclusions, offering accurateanatomical 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 yetdescribed in literature.
