Endovascular Emergency Management of Hepatic Pseudoaneurism with Vascular Plug 4 System with Sacrifice of the Aneurism Nutrient Artery (Report of 2 Cases)

Abstract

Pseudoaneurisms are arterial wounds that affect all layers of an artery; although very rare they are mostly lethal and most of them are iatrogenic. Herein, we present two different cases of hepatic artery pseudoaneurysms derived from previous surgeries which were assessed by computed tomography angiographies and consequent conservative endovascular approaches with arteriographies, posterior cannulations and the placement of Amplatzer Vascular Plug 4 (AVP 4) systems in order to treat the pseudoaneurysm. Computed control tomographies were conducted showing no later complications. The purpose of this article is to demonstrate the importance and current clinical applications of AVP in the field of interventional radiology.
