彩色多普勒超声心动图诊断肺动脉吊带的临床价值

The Diagnostic Value of Echocardiographic Diagnosis in Pulmonary Artery Sling

目的：探讨彩色多普勒超声心动图对肺动脉吊带早期诊断的价值.方法：以经螺旋CT重建和手术证实的6例肺动脉吊带患儿为研究对象,回顾分析其多普勒超卢心动图特点及漏诊原因.结果：6例肺动脉吊带患儿,多普勒超卢心动图确诊5例,诊断率为83.3%：漏诊1例,漏诊率16.7%.4例合并先天性心脏病,1例合并房间隔缺损,2例室间隔缺损,1例法洛四联症.CT诊断及手术证实6例均合并气管狭窄.x2检验彩色多普勒超声心动图与螺旋CT重建两种方法诊断准确性方面无统计学意义.结论：彩色多普勒超卢心动图诊断安全,无痛,操作简便,对肺动脉吊带早期确诊具有重要的临床意义.

Objective：To explore the value of color Doppler echocardiography in diagnosing pulmonary artery sling （ PAS ） in 6 cases in PLA 309 Hospital.Methods：From May 1998 to August 2009, 6 patients with the PAS confirmed by spiral computed tomograph reconstruction and surgery were research subjects. Characteristics of the color Doppler echocardiography and missed diagnosed reasons were analyzed.Results：5 patients （83.3%） were diagnosed on echocardiography; the other one patient （16.7%） was missed diagnosed. Four cases were complicated with congenital cardiovascular disease, including one case of atrium septal defect （ASD）, 2 cases of ventricular septal defect （VSD）and 1 case of tetralogy of Fallot （TOF）. Six cases were associated with tracheal stenosis comfirmed by CT and sugery. Compared color doppler echocardiogram with spiral CT reconstruction, Chi-square test show that two way of diagnosis have not statistically significant. Conclusion：Doppler echocardiography can make correct diagnosis of the PAS due to safety, painlessness and convenience. It is very important for early diagnoses of the PAS.
