Primary Stroke and Failure-to-Rescue Following Thoracic Endovascular Aortic Aneurysm Repair

OBJECTIVE: To characterize the impact, on failure to rescue, of cerebrovascular accident as a first postoperative complication after thoracic endovascular aortic aneurysm repair (TEVAR). DESIGN: A retrospective cohort study using of National Surgical Quality Improvement Program Participants User File. SETTING: United States hospitals taking part in the National Surgical Quality Improvement Program. PARTICIPANTS: Patients >18 years, who underwent TEVAR for nonruptured thoracic aortic aneurysm between 2005 and 2018, and developed one or more major postoperative complications within 30 days after surgery. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Out of 3,937 patients who underwent TEVAR for nonruptured thoracic aneurysm, 1,256 (31.9%) developed major postoperative complications (stroke incidence: 11.4% [143/1256]).
