目的 评价超声心动图对部分型肺静脉畸形引流 (PAPVC)和完全型肺静脉畸形引流 (TAPVC)的诊断价值。方法 回顾分析 9例TAPVC及 4 2例PAPVC的超声心动图特征 ,并与手术结果相对照。超声检查内容包括二维及彩色多普勒显像 ,多部位、多切面观察肺静脉开口部位、引流途径及数目、合并畸形情况 ,并测量各房室腔大小及三尖瓣返流峰速 ,估测肺动脉压力。结果 4 2例PAPVC患者中术前正确诊断 32例 (76 % ) ,漏诊 10例 (2 4 % )。 9例TAPVC患者中术前正确诊断 9例 (10 0 % )。结论 超声心动图是肺静脉畸形引流患者术前诊断的首选方法 ,如能多部位、多切面仔细观察 ,则可对肺静脉畸形引流作出准确的定性及分型诊断
Objective To evaluate the value of echocardiography in the diagnosis of partial-type pulmonary venous anomalies (PAPVC) and complete pulmonary venous anomalies (TAPVC). Methods The echocardiographic features of 9 cases of TAPVC and 42 cases of PAPVC were retrospectively analyzed and compared with the results of surgery. Ultrasound examination included two-dimensional and color Doppler imaging, multi-site, multi-section observation of the pulmonary venous opening, drainage channels and the number of merger deformity, and measuring the size of each atrioventricular cavity and tricuspid regurgitation peak velocity, assessment Measure pulmonary artery pressure. Results 32 patients (76%) were diagnosed correctly in 4 cases of PAPVC before operation, and 10 cases (24%) missed the diagnosis. 9 cases of TAPVC patients correctly diagnosed in 9 cases (100%). Conclusions Echocardiography is the first choice for preoperative diagnosis of patients with pulmonary venous anomalies. If multiple sites and multi-sections are carefully observed, accurate diagnosis and classification of pulmonary venous anomalies can be made
