先天性主动脉缩窄的超声诊断价值

目的探讨二维及彩色多普勒超声心动图对先天性主动脉缩窄(CoA)的诊断价值。方法回顾性分析35例CoA患者的二维及多普勒超声表现,并与手术结果作对照。结果35例患者均经手术证实为CoA,其中超声检出31例,1例被误诊为主动脉弓离断,3例漏诊;3例为单发CoA,32例均合并有室间隔缺损(VSD,18例)或动脉导管未闭(PDA,19例)或二者兼存或其他畸形;11例伴有肺动脉高压;1例伴有感染性心内膜炎。结论超声心动图检查是诊断CoA及其他合并畸形的有效方法,具有无创、快速、准确性较高的优点,可作为首选方法;胸骨上窝声窗的常规检查有助于避免漏诊。

Value of echocardiography in diagnosis of coarctation of aorta

Objective To evaluate the diagnostic value of echocardiography in coarctation of the aorta (CoA). Methods The ultrasonic findings and clinic data in 35 cases were analyzed. Results Thirty-five cases of CoA were confirmed with surgeries. 31 were preoperatively discovered by echocardiography, while one misdiagnosed as interrupted aortic arch (IAA) and 3 missed diagnosis. The CoA cases presented local coarctation at aorta arch, isthmus or descending aorta, accompanying teratisms such as VSD (18 cases), PDA (19 cases), and other complication such as pulmonary hypertension (11 cases) and infective endocarditis (1 case) and so on. Conclusion Echocardiography is a reliable technique for diagnosing CoA and complications. Routine examination through suprasternal approach to assess the aortic arch is helpful for avoiding diagnostic error.
