Abstract:Objective To analyze risk factors for cerebral neurological injury after operation of acute Stanford type A aortic
dissection to CTA morphological study. Methods From January 2015 to June 2016, 110 cases of acute Stanford type A
aortic dissection patients underwent aortic arch replacement were retrospectively analyzed. Univariate and multivariate analysis
(multiple logistic regression) were used to identify the risk factors for postoperative cerebral neurological injury including
permanent neurological dysfunction (PND) and temporary neurological dysfunction (TND). Results Cerebral neurological injury
occurred in 18 cases (18%), PND 4 cases (4%) and TND 14 cases (14%). Preoperative imaging features of CTA of 18 patients with
postoperative ND: arotic arch intimal tear 17 cases (94.4%), common carotid artery dissection 15 cases (83.3%) dissection involving
right ICA 13 cases (72.2%), and low attenuation in unilateral ICA 8 cases (44.4%). Multiple logistic regression showed that arotic
arch intimal tear (OR=21.325, P=0.008), common carotid artery dissection (OR=14.441, P=0.022) and low attenuation in unilateral
ICA (OR=9.141, P=0.024) were independent risk factors for ND. Conclusion Preoperative CTA image characteristics (arotic arch
intimal tear, common carotid artery dissection, low attenuation in unilateral ICA) indicate the occurrence of ND. These signs
can indicate intracranial ischemia, provide clinical evidence for early intervention to reduce the happening of the ND.
