Resternotomy aortic root and arch replacement following previous complex type A aortic dissection requiring...

A redo sternotomy, aortic root, and arch replacement in a patient following previous complex surgical and endovascular type A aortic dissection repair is presented in this video case report. Shortly after having the initial type A aortic dissection repair with replacement of the ascending aorta, the patient developed severe visceral malperfusion due to a compressed distal true lumen and underwent emergency endovascular repair with ascending arch and descending thoracic aorta stents and chimney grafts for the aortic arch vessels as well as fenestration of the intimal flap of the abdominal aorta. Unfortunately, the patient developed permanent paraplegia and progressive symptomatic severe aortic regurgitation. The patient underwent a redo sternotomy, aortic root, and arch replacement with explantation of the ascending stent graft and chimney stent grafts. Antegrade cerebral perfusion was maintained throughout the procedure. The aortic arch was replaced using a Terumo Aortic Plexus multibranched graft distally anastomosed to the endovascular stent graft, and the innominate and left common carotid arteries were reimplanted onto the graft. The aortic root was replaced with a Bioconduit graft, using a modified Cabrol technique to reimplant the left coronary artery. A satisfactory postoperative course and computed tomography imaging highlight the feasibility of this highly complex aortic arch repair with careful preoperative planning.
