Abstract
- A 73-year-old patient who underwent an emergency coronary bypass surgery in our institution and who required postoperative extracorporeal membrane oxygenation support in December 2019 presented in August 2020 with a rapidly growing subxiphoidal, pulsating swelling. A computed tomography scan revealed a massive mediastinal pseudoaneurysm originating from an 8-mm Dacron graft that was sutured to the ascending aorta during the index surgery for arterial extracorporeal membrane oxygenation cannulation. Due to the location and extent of the pseudoaneurysm, an open surgical revision was deemed high risk. Because no bypass conduit originated from the ascending aorta, we decided to occlude the entry of the pseudoaneurysm with a stent graft. Also, urgency did not allow for the manufacturing of a custom-made device, so an off-the-shelf stent graft had to be implanted. Currently, the only off-the-shelf thoracic stent graft with a length suitable for the ascending aorta (<7 cm) is the Medtronic Valiant Navion prosthesis, of which 2 prostheses (37 mm × 52 mm; covered seal) were successfully implanted to exclude the pseudoaneurysm. A follow-up computed tomography scan performed 4 months postoperatively showed no perfusion and regression of the pseudoaneurysm. With the growing number of reports describing stent graft placement in the ascending aorta, more off-the-shelf stent grafts suitable for the ascending aorta are desirable. [ABSTRACT FROM AUTHOR]
