A Case of Type A aortic Dissection in Which Blood Flow in Left Common Carotid Artery Disappeared Immediately after Commencement of CPB via Right Subclavian Artery and Surgical Repair Was Achieved Using Femoral Artery Cannulation

Abstract

The patient is a 41-year-old man, who underwent emergency surgery for Stanford type A AAD. Immediately after CPB was commenced via the right subclavian artery, NIRO dropped and blood flow in the left common carotid artery disappeared. Switching to the left femoral artery cannulation resulted in improvement in left common carotid artery blood flow and NIRO. The patient underwent total arch replacement surgery and was discharged on postoperative day 20 with no neurological sequelae. We report this case as an example of trouble-shooting for malperfusion syndrome during acute aortic dissection surgery.
