Iatrogenic Segmental Renal Artery Pseudoaneurysm: A Case Report

Abstract

Pseudoaneurysm is a false aneurysm that occur at the site ofarterial injury that involves one or more layers of the arterialwall but no all three layers of the wall [1]. The renal artery pseudoaneurysm is a rare clinical entity due to iatrogenic procedures like percutaneous procedures, renal biopsy, nephrectomy or to penetrating or blunt traumas [2,3]. The clinical can be different according to patient blood pressure, blood flow and also to the effectiveness of the hemostasis. This complication can lead to hematuria, blood loss, and even hemorrhagic shock secondary to rupture (rare event but with a mortality rate as high as 80%) [4]. Aneurysms larger than 2 cm in diameter are considered to have a high risk of rupture, although ruptures have also been reported in smaller aneurysm [5].
