Use of covered stent devices for false lumen embolization in chronic dissection: a novel approach.

Abstract

Thoracic endovascular aortic repair (TEVAR) is effective in treating acute complicated dissection, but in the chronic state it is frequently complicated by persistent retrograde false lumen perfusion that results in treatment failure. We describe a novel endovascular technique and present an illustrative case of a patient with chronic dissection for which covered stent devices were used as an adjunct to TEVAR to occlude the distal thoracic false lumen and interrupt retrograde perfusion. The case demonstrates that this strategy promotes remodeling when used in addition to stent grafting the true lumen for chronic dissection.
