Insights
Aortic dissection Stanford Type A was treated with aortic repair and graft reinsertion. A later pseudoaneurysm required reoperation for ascending aorta replacement, with successful outcomes.
Area of Science:

- Vascular Surgery
Background:
- A 63-year-old male with hypertension and prior coronary artery bypass grafting presented with acute chest pain.
- Initial evaluation suggested bypass graft dysfunction, but angiography revealed Stanford Type A aortic dissection.
Abstract:
A 63-year-old man with a history of hypertension and coronary artery bypass grafting (1 year ago) was admitted with acute onset severe chest pain suggesting bypass dysfunction. Biplane cineangiography revealed acute aortic dissection Stanford Type A without involvement of the aortic valve, the coronary arteries or the proximal anastomoses of the two venous bypass grafts, one of which was occluded. Urgent repair of the aorta by a prosthesis and reinsertion of the patent venous graft in the innominate artery by interposition of saphenous vein was performed without complications. Sixteen months later on routine follow-up a pseudoaneurysm of the ascending aorta surrounding the aortic prosthesis was discovered by transesophageal echocardiographic examination. Reoperation was performed with prosthetic replacement of the ascending aorta. The operative course and further follow-up of now 1.5 years were uneventful.
