Among 62 patients who underwent hybrid arch TEVAR, which is a combination of supra-aortic bypass and TEVAR to treat arch aneurysm, 5 patients encountered postoperative cerebral infarction. In 2 patients, whose thoracic aorta were extremely shaggy, cerebral infarction were multiple and fatal. Other 3 patients, whose aorta were not shaggy, developed visual disturbance after TEVAR and minor cerebral infarction were detected in the area of vertebral artery. To prevent cerebral infarction after hybrid arch TEVAR, the blood flow from the left subclavian to vertebral artery is considered to be significant.
