彩色多普勒超声心动图诊断主动脉缩窄

Diagnosis on coarctation of aorta using color Doppler echocardiography

目的:探讨多普勒超声心动图对主动脉缩窄的诊断价值。方法:回顾性分析10例主动脉缩窄患者多普勒超声心动图检查结果与手术所见。结果:10例患者术前超声心动图检查诊断正确8例,漏诊2例(其中升主动脉管性缩窄1例,主动脉嵴部缩窄1例)。结论:彩色多普勒超声心动图能准确显示主动脉缩窄部位;动脉导管未闭(PDA)患者应常规探查主动脉弓及降主动脉。

Objective：To study the value of diagnosis of coarctation of the aorta（COA） by color Doppler echocardiography. Methods： We retrospectively analysed 10 patients with COA diagnosed by color Doppler echocardiography and pathology. Results：8 of the 10 patients were successfully diagnosed using color Doppler echocardiography and 2 patients misdiagnosed.5 patients had both PDA and coarcration of aortia. Conclusions： Color Doppler echocardiography can accurately diagnose the location of COA. The patient with PDA should be checked the decending aorta.
