目的 :探讨超声诊断部分型肺静脉异位引流 (PA PVC)的价值和超声心动图特征 .方法 :研究经手术或心血管造影证实的 34例PAPVC和 2 0例继发孔房缺 (SASD)超声心动图结果 .并将PAPVC和SASD心脏形态学改变进行对比 .结果 :34例PAPVC中 ,肺静脉连接上腔静脉 (SVC) 2例 ,左垂直静脉 1例 ,右房 (RA) 2 4例 ,冠状静脉窦 6例及SVC和RA混合型 1例 .34例中单支异常连接 7例 (2 0 .6 % ) ,双支 2 5例 (73.5 % ) ,三支 2例 (5 .9% ) .超声心动图诊断正确率 70 .6 % (2 4 /34) ,其中漏诊异位引流的肺静脉 ,但发现SASD 9例 ,SASD合并室缺 1例 .PAPVC常见合并畸形为SASD占 6 4 .7% (2 2 /34) .PAPVC及SASD的右房、右室 (RV)校正值和RA/LA、RV/LV比值均增大 ,两组间的比值增大有显著性差异 (P <0 .0 5 ) .结论 :当RA/LA比值 >1.5及肺静脉连接及进入位置和血流方向对该畸形的诊断具有明确意义 .本结果提示应将肺静脉开口位置和血流作为常规检查项目 .
AIM: To study the diagnostic value and the imaging characteristics of partial anomalous pulmonary venous connection (PAPVC) by echocardiography. METHODS: Thirty four patients with PAPVC and 20 patients with secondary atrial septal defect (SASD), who had been confirmed by operation or angiography, were involved in the study. PAPVC and SASD were compared in heart morphology. RESULTS: The connection of pulmonary veins in patients with PAPVC was as follows: 2 case in superior vena cava (SVC), 1 in left vertical vein, 24 in right atria (RA), 6 in coronary sinus and 1 in both SVC and RA. 7 cases (20.6%) had single connection of an anomalous vein, 25 cases (73.5%) had the connection of two anomalous veins and 2 cases (5.9%) had the connection of three anomalous veins. By echocardiography, the accuracy of diagnosis was 70.6% (24/34). Of the 10 cases were misdiagnosed, SASD was found in 9 cases and SASD with ventricular septal defect in 1 case. In PAPVC, the most commonly accompanied malformation was SASD (22/34). Corrected diameter of right atrium (RA) and right ventricle (RV) increased in both PAPVC and SASD. Ratios of RA to LA and RV to LV were significantly different ( P <0.05) between PAPVC and SASD although they all increased in PAPVC and SASD. CONCLUSIONS: The ratio of RA/LA>1.5 is an important index for the diagnosis of PAPVC and the pulmonary venous connection should be included in routine examination.
