Aim: Herein, we aimed to present our results of thoracic and abdominal endovascular aortic repair (EVAR/TEVAR) procedures for thoracoabdominal aortic pathologies and the relation between the post-procedural neurological adverse events and in-hospital mortality. Material and Method: Patients who underwent EVAR/TEVAR procedures between November 2016 and May 2021 were included in this retrospective study. Patients with a history of any cerebrovascular event before the intervention were excluded. Patients were divided into two groups according to the occurrence of any early neurological complications in the postoperative period in hospital. Results: A total of 47 patients were included in this retrospective study. Group 1 included 37 (78.7%) patients who had no neurological complications in the early postoperative period. Group 2 included 10 (21.3%) patients who had a postoperative neurological complication. The intensive care unit (ICU) stay time was significantly longer in Group 2 compared with Group 1 (1.7 ± 2.0 days in Group 1 vs 6.2 ± 5.1 days in Group 2, p = 0.021). The overall mortality rate was 19.1% (9 of 47 patients). The mortality rate of Group 2 was significantly higher than Group 1 (2 of 37 [5.4%] patients in Group 1 vs 7 of 10 [70%] patients in Group 2, p = 0.001). The American Society of Anesthesiologists (ASA) physical classification score was significantly higher in Group 2 than Group 1 (3.5 ± 0.6 in Group 1 vs 4.1 ± 0.3 in Group 2, p = 0.016). The most common early postoperative neurological complication was a lack of recovery of consciousness in the postoperative period (no postoperative consciousness).
Conclusion:The occurrence of any postoperative neurological adverse event is associated with in-hospital mortality following TEVAR/EVAR procedures.
