Deskripsi
<i>Background and Objectives</i>: Postoperative neurological complications (NCs) are an important cause of mortality in patients with acute type A aortic dissection (ATAAD). The aim of the study was to determine the association between intraoperative risk factors and newly developed postoperative NCs in patients after emergency surgery for ATAAD. <i>Materials and Methods</i>: A total of 203 patients requiring emergency surgery were included in the study. Patients with preoperative neurological dysfunction, deceased on the operating table or within the first 48 h after intensive care admission, with uncertain postoperative neurologic status or with incomplete records were excluded. <i>Results</i>: Mean age was 57.61 ± 12.27 years. Hyperlipidemia was the most frequent comorbidity (69%). A bicuspid aortic valve was present in 12.8% of cases, severe acute aortic regurgitation was present in 29.1% of patients, and cardiac tamponade was present in 27.1% of cases. The innominate artery was the most frequently dissected supra-aortic artery in 27.1% of cases. In 65% of cases, the primary entry tear was at the level of the ascending aorta. The incidence of newly developed postoperative NCs was 39.4%. The most common surgical technique performed was supra-coronary ascending aorta and hemiarch replacement, in 53.2% of patients. Using logistic regression, cardiopulmonary bypass time (OR = 1.01; 95% CI = 1.01–1.02; <i>p</i> < 0.001), aortic cross-clamp time over 3 h (OR = 2.71, 95% CI = 1.43–5.14, <i>p</i> = 0.002) and cerebral perfusion time (OR = 1.02; 95% CI = 1.002–1.03; <i>p</i> = 0.027) were independently associated with newly developed postoperative NCs. <i>Conclusions</i>: Based on the results of the study, all efforts should be made to reduce operative times. Using a simple surgical technique, like the supra-coronary ascending aorta and hemiarch technique, whenever possible, and using a simpler technique for cerebral perfusion like unilateral cerebral perfusion via the right axillary artery, could reduce operating times.
