Trends in the use of cerebrospinal drains and outcomes related to spinal cord ischemia after thoracic endovascular aortic repair and complex endovascular aortic repair in the Vascular Quality Initiative database

Prophylactic CSFD use with TEVAR/cEVAR has remained stable over time. Among SCI patients, a postoperative therapeutic CSFD was associated with worse sustained neurologic outcome and overall survival compared to those with preoperative prophylactic drains. These findings highlight the need for a randomized clinical trial examining prophylactic vs therapeutic CSFD placement with TEVAR/cEVAR.
