Abstract:
Objective To investigate the feasibility of combined CT angiography(CTA)of head,neck and aorta in acute type A aortic dissection (ATAAD) and whether the incremental craniocervical information benefits the surgeon and leads to improved clinical outcomes.Methods One hundred and twenty ATAAD patients in a CAC group underwent combined aortic CTA and 123 ATAAD patients in a control group underwent conventional aortic CTA.In the CAC group,the image quality was analyzed and critical CTA findings in craniocervical arteries were determined for further surgery procedure.The radiation dose,intraoperative cerebral protection method,and postoperative intensive care units(ICU)time,in-hospital time,neurologic dysfunction(ND)and all-cause mortality were compared between the two groups.Results The CAC group had all the carotid and cerebral arteries diagnosed successfully. There were 13 patients replaced conventional unilateral antegrade selective cerebral perfusion with bilateral one according to the head and neck CTA images in the CAC group. The CAC group had effective radiation dose,postoperative ND,ICU time and in-hospital time significantly lower than those of the control group (P<0.05).There were no statistical differences between the all-cause morbidities of the two groups (P>0.05).Conclusion A combined CTA of head, neck and aorta in ATAAD is feasible. The incremental craniocervical information may lead to improved clinical outcomes.
