Embolization of isolated hypogastric artery aneurysm: a case report and a review of the literature.

A 75-year-old man with arterial hypertension, coronary artery disease, and myocardial infarction was referred to our service because of an asymptomatic hypogastric artery aneurysm (HAA) detected by a routine computed tomography (CT) scan. As shown on the angio-CT the maximum transverse diameter (m.t.d.) of the HAA was 47 mm. There were no symptoms of distal embolization or compression on the pelvic structures. We performed the successful complete thrombosis of the aneurysm using vascular plugs via a controlateral femoral approach. The control angiogram was satisfactory and there were no intraoperative complications. A CT-angiography done 4 months after the procedure showed no signs of refilling of the aneurysm sac. This case illustrates some possible advantages of vascular plugs in the treatment of isolated HAA.
