Double-lumen atherosclerotic abdominal aortic aneurysm

Abstract

A 66-year-old white man was diagnosed with an asymptomatic abdominal aortic aneurysm by ultrasound imaging. The patient provided informed consent to the publication of the details his case. There was a history of tobacco use and hypertension, and no registry of prior abdominal trauma. As part of the preoperative evaluation, a computed tomography angiography was performed, 1,2 which confirmed the presence of a fusiform aneurysm of the infrarenal abdominal aorta measuring 6.8 (anteroposterior) Â 6.7 (laterolateral) Â 11.0 (extension) cm containing bulky intraluminal thrombus. The volume-rendered sagittal (A/Cover) and coronal (B) images revealed the presence of an aneurysm with two separated lumens produced by tunneled recanalization of the thrombus at the anterior wall, without signs of aneurysm dissection or contained rupture. In the anterior lumen was the emergence of the inferior mesenteric artery.The patient underwent an uneventful open surgical repair. The presence of a double-lumen thrombus-recanalized atherosclerotic abdominal aortic aneurysm was confirmed during surgery.
