Understanding the risk factors and pathophysiology of neurological complications like spinal cord ischemia and stroke is crucial for managing patients undergoing TEVAR.
Thoracic endovascular aortic repair (TEVAR) has decreased the morbidity and mortality associated with open surgical repair of descending thoracic aortic diseases, but important complications unique to the procedure remain. Spinal cord ischemia and infarction is a recognized complication caused by endovascular coverage or injury to spinal cord collateral vessels. Stroke is a consequence of thromboembolism or coverage of aortic arch branch vessels with insufficient collateral circulation. Understanding the risk factors and the pathophysiology of neurological complications of TEVAR are important for the successful anesthetic and surgical management and treatment of patients undergoing endovascular procedures involving the thoracic aorta.

Ullery et al. (2011) conducted a review in Descending thoracic aortic diseases. Thoracic endovascular aortic repair (TEVAR) vs. Open surgical repair was evaluated on Neurological complications (spinal cord ischemia, infarction, stroke). Thoracic endovascular aortic repair is associated with unique neurological complications, including spinal cord ischemia and stroke, requiring careful anesthetic and surgical management.
