Stent-graft treatment of type B aortic dissection involving the right aortic arch: case report.

A 56-year-old man suffered from type B aortic dissection associated with the right aortic arch and right descending aorta. The patient was successfully treated by implantation of 2 stent-grafts (a 40-mm Z-stent covered with a 37.5-mm woven Dacron graft) and ligation of the dissected left subclavian artery. A postoperative computed tomographic scan revealed thrombosis of the false lumen and a reduction in the descending aortic diameter.
