Modified Isolated Cerebral Perfusion Technique for Prevention of Stroke With Aortic Arch Replacement

In aortic arch replacement, an isolated cerebral perfusion method has been reported in additional to axillary artery cannulation to prevent postoperative stroke. We have made changes to this method. In other words, we devised a method to reduce cerebral embolism by performing selective cerebral perfusion via an artificial graft anastomosed to the left common carotid artery and the left subclavian artery. This method was performed in 7 cases, and all patients were discharged alive without any neurological disorders. In the surgical procedure of the aortic arch, sufficient care must be taken in the manipulation around the brachiocephalic artery and the left subclavian artery. Our method can avoid reinsertion due to desorption of the cerebral perfusion cannula and can be expected to prevent postoperative stroke.
