Common iliac artery aneurysm urological manifestations

An iliac artery aneurysm is a permanent and focal dilation of the artery that measures more than 50% of the normal diameter of the vessel. Isolated iliac artery aneurysms are infrequent, mostly as an association with an abdominal aortic aneurysm. The objective of this article is mainly to focus on urological symptoms as the manifestations of iliac artery aneurysm, to propitiate an early diagnosis.

In this article, we present a clinical case of a patient with generalized weakness, an episode of lipothymia and pain in the renal fossa, finding three aneurysms in the computed tomography, located in the right common iliac artery, the left internal iliac artery and the left external iliac artery. Later, the patient presents urological complications, after an obstruction of the right ureter, and therefore, a right hydronephrosis and loss of renal parenchyma function. Given this, urgent surgery is performed with satisfactory results.

The diagnosis of an iliac aneurism represents a challenge since most patients are asymptomatic. As main manifestation, urinary compression symptoms represented a fundamental part of diagnostic suspicion, which coincides with other similar cases reported in the literature.
