Involution of aneurysmal collateral arteries after correction of aortic coarctation.

A 47 year-old man with aortic coarctation had undergone extra-anatomic bypass through a left thoracotomy. He presented 10 years later with uncontrolled arterial hypertension due to residual aortic coarctation, graft obstruction and multiple collateral artery aneurysms between the subclavian artery and the aorta. He underwent extra-anatomic correction between the ascending aorta to descending aorta through a median sternotomy with the aid of conventional cardiopulmonary bypass. His postoperative recovery was unremarkable, and there was complete involution of all aneurysmal collateral arteries after the operation.
