Percutaneous treatment of dissection of the ascending aorta occurring as a complication during coronary angioplasty of a saphenous vein bypass graft.

Aortocoronary dissection can occur as a complication of angioplasty of native coronary arteries. This case report is of aortic dissection occurring as a complication of percutaneous coronary intervention of proximal anastomoses of a saphenous vein bypass graft. The aortic dissection that had progressed retrogradely into the ascending aorta was treated percutaneously by stenting in the saphenous vein graft with a membrane-covered stent.
