A pitfall of false lumen embolization in chronic aortic dissection: intimal injury caused by the embolization device edge

Abstract

We report a case of intimal injury caused by the occluder device in the false lumen (FL) after treatment of refractory chronic aortic dissection with FL embolization. We speculate that the intimal injury was due to the disproportionate stress from the FL. We covered the new entry by an additional stent graft in the true lumen. The deployment of a stent device in both lumens at the level of embolization might be indispensable for FL embolization.
