Thromboaspiration of Abdominal Aortic Mural Thrombus: A New Endovascular Approach

Abstract

Primary aortic mural thrombus (PAMT) is defined as a thrombus attached to the aortic wall in the absence of any atherosclerotic or aneurysmal disease in the aorta and a cardiac source of embolus. There is no consensus on the ideal treatment of PAMT. There are a few reports of thromboaspiration of aortic thrombus in literature. The objective of this article is to report a new endovascular approach of abdominal aortic mural thrombus. The use of Penumbra Thromboaspiration System is a feasible procedure to treat abdominal aortic thrombus and may be an option for patients unsuitable for open repair or conservative treatment.

Use of Wallstent device as an embolic protection device during stenting of aortic thrombus

“…Endovascular options described in the treatment of aortic mural thrombus include stent grafts, 5 , 8 bare metal stents, 8 , 9 , 10 and thrombus aspiration. 11 The use of stent grafts allows for the exclusion of the thrombus, covering any underlying lesion such as an atherosclerotic plaque. Bare metal stents have the advantage of preserving the aortic branches and are described to be safe and effective, 10 although the potential risk exists of allowing a part of the thrombus to squeeze through the mesh of the bare metal stent.…”
