超声心动图诊断肺动脉吊索

目的 探讨超声心动图在肺动脉吊索诊疗中的应用价值.方法 分析经CT、心导管造影和(或)手术证实的6例肺动脉吊索患儿的超声心动图表现及诊断要点.结果 6例肺动脉吊索患儿中,超声诊断4例,漏诊1例,误诊1例.6例中3例合并房间隔缺损,1例伴有卵圆孔未闭,2例伴有室间隔缺损,1例伴有动脉导管未闭,1例伴有法洛四联症,1例伴有永存左上腔静脉.结论 超声心动图可探查左、右肺动脉的起始位置及走行,有助于正确诊断肺动脉吊索.

Application of echocardiography in diagnosis of pulmonary artery sling

Objective To explore the value of echocardiography in diagnosing pulmonary artery sling (PAS). Methods Six children were diagnosed as PAS with CT, cardiac catheterization and/or surgical operation. Echocardiographic manifestations and diagnostic points of PAS were retrospectively analyzed. Results Among 6 children with PAS, 4 were diagnosed correctly by echocardiography, while 1 was missed diagnosed and 1 was misdiagnosed. In 6 children with PAS, 3 were combined with atrial septal defect, 1 with patent foramen ovale, 2 with ventricular septal defect, 1 with patent ductus arteriosus, 1 with tetralogy of Fallot and 1 with persistent left superior vena cava. Conclusion Echocardiography can present the origin and branches of left and right pulmonary artery, therefore being helpful to correct diagnosis of PAS.
