One size does not fit all: case report of two percutaneous closures of aortic pseudoaneurysm and review of the literature.

Aortic pseudoaneurysms (PSAs) are common complications following cardiac surgery, and carry significant morbidity and mortality. Surgical management of aortic PSAs is associated with high mortality, however there are emerging reports of transcatheter techniques for closure of aortic PSAs. We present two cases of ascending aorta PSA which developed following cardiac surgery and were treated percutaneously with novel closure devices. We also describe a comprehensive review of the literature of all published cases of ascending aorta PSA which have been closed percutaneously, and report on the success rate and available devices for percutaneous closure.
