Abstract

Among the complications of endovascular abdominal aortic aneurysm repair the most common are the so–called endoleaks - the preservation of blood flow inside an isolated aneurysmal sac. This complication occurs in almost every fourth patient and is the main cause of reinterventions, which makes the late development of this complication one of the urgent problems under discussions. The report presents a clinical case of treatment of a patient with an aneurysm of the infrarenal abdominal aorta with its spread to the common iliac artery using the technique of preventive embolization of the internal iliac artery with application of a liquid tantalum-containing ethylene vinyl alcohol copolymer. All stages of the operation were performed in the catheterization laboratory using a stationary angiographic system. The embolizing material was introduced after implantation of the stent-graft into the target position, through a microcatheter pre-installed at the ostium of the embolizing internal iliac artery. The introduction of a tantalum-containing ethylene vinyl alcohol copolymer after the installation of the stent-graft, under conditions of significant reduction of arterial antegrade blood flow in the lumen of the internal iliac artery, allowed to create a reliable occlusion of the ostium segment of the artery, reduced the risk of migration of embolizing substance into the distal arterial bed.
