Comparison research on CT features and clinic data of congenital coarctation of the aorta / 局解手术学杂志

ABSTRACT

Objective To compare the CT features and clinic data of patients with congenital coarctation of the aorta ( CoA) and com-plex CoA. Methods CT findings and clinical characteristics of 29 patients with CoA were retrospectively analyzed and compared. Results There were difference in clinical characteristics between isolated COA and complex COA(P<0. 05). Local COA, aortic isthmus COA, associated with patent ductus arteriosus, bicuspid aortic valve were more than those of complex COA(all P<0. 05). Grade of vascular steno-sis in patients with isolated COA was higher than ones with complex COA. Isolated COA associated with vascular variations and aorta malfor-mation were less than those of Complex COA(P<0. 001). More cardiacvascular malformation were common in patients with complex COA, collateral circulation were in in all patients with isolated COA. Conclusion There were differences of CT findings in patients with different COAs. CT findings would be helpful for early diagnosis, treatment in early stage, and choice of treatment.
