摘　　要：目的探讨2种类型的先天性主动脉缩窄(COA)的CT及临床特征差异。方法回顾性对比分析29例COA患者临床表现及CT特征。结果复合型多见于儿童、缺氧常见、体重指数低、上下肢压差高、股动脉搏动弱和下肢血氧饱和度低,单纯型多见于成人、高血压患者,2种类型比较,差异有统计学意义(P<0.05)。患者CT影像特征提示单纯型局限性狭窄和合并变异血管发生率少于复合型(P<0.05),而单纯型主动脉峡部缩窄明显多于复合型(P<0.05),单纯型狭窄程度重于复合型(P<0.05)。单纯型合并主动脉瓣二瓣畸形和合并动脉导管未闭多于复合型(P<0.05),单纯型合并主动脉畸形/发育不良明显少于复合型(P<0.05),复合型COA多合并其他心血管畸形或变异,单纯型均伴有侧支循环。结论 2种类型COA的临床表现和CT特征不同,明确这种差异有助于COA患者的早期诊断、早期治疗及治疗方式的选择。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.
