Endovascular stent grafting of the descending thoracic aorta after arch repair in acute type A dissection.

Abstract

An endovascular stent graft was successfully deployed to the primary entry site in the proximal descending thoracic aorta after total aortic arch replacement using the "elephant trunk" technique in acute type A aortic dissection. The residual false lumen of the descending aorta was thrombosed completely after stent grafting. The elephant trunk was feasible for a proximal landing zone for stent grafting of the descending aorta. Stent grafting in combination with aortic arch replacement was a safe and effective procedure, and may be an alternative choice in carefully selected patients with type A aortic dissection.
