Abstract:
Objective To analyze preoperative CT angiography (CTA)imaging features of cervical arteries in patients with acute type A aortic dissection followed by postoperative neurological dysfunction (ND),and the correlations between risk factors and ND.Methods Clinical and imaging data of 110 patients who underwent repair of acute type A aortic dissection were analyzed retrospectively.The samples were categorized into two groups based on the presence or absence of ND.The clinical,perioperative and imaging data were compared between the ND group and the non ND (NND)group.Univariate and multivariate analyses were performed to identify predictors related with ND.Results A total of 100 patients were finally included in this study,and 18 patients(18%)developed with ND after aortic surgery.No significant differences in clinical and perioperative variables were observed between the ND group and the NND group (P＞0.05).However,on preoperative CT images,a dissection entry localized in the aortic arch (94.4% in the ND group), common carotid artery tear (83.3% in the ND group)and unilateral internal carotid artery density decrease (44.4% in the ND group) were all significantly higer than those in th NND group (P＜0.05 ).No significant difference were observed in true lumen stenosis of ascending aorta (P=0.053),retrograde dissection (P=0.913)and intimal tear (P=0.267)between ND group and NND group.The Logistic regression analysis revealed that a dissection entry localized in aortic arch (OR=21.325,P=0.008),common carotid artery tear (OR=14.441,P=0.022)and unilateral internal carotid artery density decrease (OR=9.141,P=0.024)were independent determinants of postoperative ND.Conclusion Preoperative CTA of cervical arteries can provide more imaging features,that may be indicative of postoperative ND.
