应用超声心动图评价完全性肺静脉异位引流患儿术后并发症的研究

Evaluation of Post-operative Complication in Patients With Total Anomalous Pulmonary Venous Connection by Echocardiography

目的:应用超声心动图监测完全性肺静脉异位引流(TAPVC)患儿术后肺静脉梗阻等并发症的发生。方法:对我院66例TAPVC患儿术前,术后围手术期、中期超声心动图测量值进行回顾性分析,监测肺静脉梗阻等并发症的发生。结果:66例TAPVC患儿术后围手术期、中期超声心动图测量左心室舒张末期内径均较术前增大,右心室前后径均较术前减小,差异存在统计学意义(P<0.05)。术后出现肺静脉梗阻6例患儿应用超声心动图可观测到吻合口处或肺静脉回流处的高速血流信号。6例肺静脉梗阻患儿术后围手术期左心室舒张末期内径较术前增大,右心室前后径缩小,肺动脉压力降低,差异存在统计学意义(P<0.05),术后中期左心室舒张末期内径较术前增大,差异存在统计学意义(P<0.05),但右心室前后径、肺动脉压力均较术前差异无统计学意义(P>0.05)。结论:超声心动图可动态监测完全性肺静脉异位引流的手术效果,通过右心室前后径及肺动脉压力等测量值可监测术后肺静脉梗阻的发生。

Objective： To evaluate the post-operative complication of pulmonary vein stenosis in patients with total anomalous pulmonary venous connection （TAPVC） by echocardiography. Methods： A total of 66 TAPVC pediatric patients with surgical repair in our hospital were retrospectively studied. The peri-operative and mid-term post-operative echocardiography was conducted to evaluate the complication of pulmonary vein stenosis. Results： The peri-operative and mid-term post-operative echocardiography presented the increased left ventricular diastolic end diameter （LVEDd） and decreased right ventricular diameter in all 66 patients, P〈0.05. There were 6 patients with pulmonary vein stenosis showed high velocity Doppler signals at atanastomosis. The peri-operative echocardiography in those 6 patients showed increased LVEDd, decreased right ventricular diameter and pulmonary artery pressure, all P〈0.05. The mid-term post-operative echocardiography in those 6 patients indicated increased LVEDd, P〈0.05, while the right ventricular diameter and pulmonary artery pressure were similar before and after the operation, P〉0.05. Conclusion： Echocardiography may monitor the operative effect of TAPVC, the occurrence of post-operative pulmonary vein stenosis could be found by examining right ventricular diameter and pulmonary artery pressure in pediatric patients.
