What is Ascending Aortic Aneurysm ?

Ascending Aortic Aneurysm :  In aneurysms confined to ascending aorta well below the innominate artery origin, the technique used is resection and replacement with a Dacron tube graft. At times the aortic root is also dilated and there is significant aortic regurgitation. Then the technique used is a Bental procedure where the ascending aorta, root and valve we replaced with a composite graft of prosthetic aortic valve'sutured into a suitably sized albumin impregnated dacron graft. First, the composite valved graft is sutured to the aortic annulus. Two, coronary arterial buttons are raised and anastomosed to the tube graft. Finally, the distal anastomosis is done below the innominate artery. Deairing is done before releasing aortic clamp and allowing the heart to beat.

Associated coronary artery disease is treated by bypass grafting. Distal anastomoses are done before aneurysm is grafted. Proximal anastomoses are done to the tube graft while rewarming.
