title: [A case of rupture of the ascending aorta owing to prosthetic graft dilation following replacement of the descending aorta].
abstract: A 55-year-old male was diagnosed as acute type A aortic dissection caused by retrograde propagation from a tear in the descending aorta. A replacement of the descending aorta was performed with a prosthetic graft (VASCUTEK). Sixteen days after the operation, the patient required an emergency operation due to a rupture in the ascending aorta. Transesophageal echo and contrast enhanced CT indicated the point of entry to be at the proximal anastomotic portion of the prosthetic graft and the prosthetic graft (30 mm in diameter) to be dilated to 45 mm. Intimal tear at anastomotic portion owing to graft dilation was suspected as the main factor causing rupture of the ascending aorta.
