Abstract 20483: Characterization of Type B Acute Aortic Dissection Patients With Presenting Spinal Cord Ischemia

Introduction: Spinal cord ischemia (SCI) is a devastating complication of type B acute aortic dissection (TBAAD). Several studies have focused on TBAAD patients who develop post-procedure SCI, but there is minimal data on TBAAD patients who develop SCI as a consequence of dissection, either pre-procedure or with medical management alone. This study aims to better characterize these patients. Methods: This study looked at TBAAD patients enrolled in the International Registry of Acute Aortic Dissection (IRAD) with presenting SCI (n=52), defined as those who were either diagnosed with SCI at admission (n=41), were medically managed and developed SCI in-hospital (n=3), or were procedural patients who developed SCI in-hospital prior to surgery or endovascular therapy (n=8). Clinical factors and in-hospital and post-discharge outcomes associated with SCI were evaluated. Results: Presenting clinical factors associated with presenting SCI included pulse deficits (46.5% v. 24.8%, p=0.001), ischemic peripheral neur...
