Preoperative Inferior Mesenteric Artery Embolization is a Cost-effective Technique that May Reduce the Rate of Aneurysm Sac Diameter Enlargement and Reintervention After EVAR.

Background: Type II endoleaks are the most common complications after endovascular repair of abdominal aortic aneurysms (EVARs). Some studies have shown the benefit of preventive inferior mesenteric artery (IMA) embolization, but its efficacy and cost-effectiveness continue to be controversial. The aim of this study was to evaluate the efficacy of this procedure on the increase in aneurysmal sac diameter during follow-up.

Emergency Embolization of a Ruptured Aneurysm of the Internal Iliac Artery by Direct Ultrasound-Guided Puncture: Report of a Case.

We report the emergency embolization of a ruptured aneurysm of the internal iliac artery in a patient at high surgical risk. Admission computed tomography scan showed that the ostium of the aneurysmal internal iliac artery was covered by a covered stent. In this patient, we chose to carry out an embolization of the aneurysm and its efferent arteries by direct puncture of the aneurysmal sac using an antero-external abdominal approach under ultrasound guidance.
