Abstract

Background and Goal of Study: Neurologic deficit is a devastating complication of thoracoabdominal aortic aneurysm repair (TAAAR) and is associated with a significant increase in both, morbidity and mortality. The purpose of this study was to identify predictors of neurologic deficit after TAAAR. Materials and Methods: The subjects for this study comprised 449 consecutive patients who underwent TAAAR between June 2003 and November 2015. Data were collected retrospectively through electronic medical records. Age, Crawford classification, acute dissection occurrence, whether surgery was elective or emergency, medical history (preoperative renal insufficiency, diabetic mellitus, cerebral infarction), aortic cross clamp time, presence of open distal anastomosis, whether intercostal arteries were reattached, and whether preoperative cerebrospinal fluid was drained were evaluated. The logistic regression with Akaike information criterion stepwise selection was performed to identify predictors of neurologic deficit. Results and Discussion: Of the 449 patients, 56 (12.5%) developed neurologic deficit. Neurologic deficit included paraplegia in 30 patients (6.6%) and paraparesis in 26 patients (5.8%). The logistic regression analysis with stepwise model selection revealed multiple significant factors for the development of neurologic deficit, including preoperative renal insufficiency (odds ratio [OR] 1.24, 95% confidence interval [CI] 1.06 - 1.44; p = 0.006), open distal anastomosis (OR 2.79, 95% CI 1.52 - 5.12; p = 0.001), and absence of intercostal artery reattachment (OR 0.47, 95% CI 0.23 - 0.96; p = 0.039). Conclusion(s): The predictors of postoperative neurologic deficit in our hospital were preoperative renal insufficiency, open distal anastomosis, and absence of intercostal artery reattachment.
