Association Between Abdominal Aortic and Common Iliac Artery Aneurysms: Case Report

The infrarenal abdominal aortic aneurysm is the most common among arterial aneurysms; it happens when there is an abnormal and irreversible enlargement of the blood vessel. This disease usually compromises other arterial segments and is linked to high mortality rates, mainly due to its rupture. Given its importance, we present a case study of an abdominal aortic aneurysm associated with a common iliac artery aneurysm. During a dissection practice in the Morphofunctional Laboratory at FACERES Medical School, we observed the presence of a mild stenosis in the abdominal aorta below the renal arteries, as well as the formation of an infrarenal abdominal aortic aneurysm. In addition, we noticed that the infrarenal abdominal aortic aneurysm was associated with a bilateral common iliac artery aneurysm. Morphological analyses carried out in the blood vessels showed a large quantity of atheromatous plaques, which are the probable cause of the pathology. The information herein may broaden the knowledge on the infrarenal abdominal aortic aneurysmal disease, thus reducing its complications and mortality rates.
