超声心动图评估完全型肺静脉异位引流合并肺动脉高压

目的应用二维及多普勒超声心动图分析完全型肺静脉异位引流(TAPVC)患者的肺动脉压力,通过术前、术后1周、术后3个月的对比,总结TAPVC患者肺动脉高压(PH)的特点及相关因素,建立评估此类疾病肺动脉高压的超声心动图方法。方法选择65例TAPVC患儿,分别于术前、术后1周、术后3个月进行超声心动图检查。通过二维超声多切面观察其心脏结构及功能。连续多普勒测量三尖瓣反流峰值压差(PTR),肺静脉干最大流速大于1.5m/s为静脉干梗阻(PVO)。建立超声评估肺动脉高压的方法。结果 65例TAPVC患儿均有显著肺动脉高压[PTR=(65.30±23.33)mmHg],13例发现有PVO。62例患者完成矫治手术。术后1周60例患儿PTR较术前明显下降(P0.01)。1例心上型TAPVC术后PTR不下降,超声发现静脉干与左心房壁吻合口狭窄。1例患儿右心回缩不明显,3个月后肺动脉压力持续增高,考虑存在肺静脉分支狭窄。术后3个月另有2例患者静脉干与左心房吻合口狭窄。其余患者术后3个月PTR下降至正常或接近正常,11例患者三尖瓣反流消失。结论 TAPVC合并肺动脉高压经手术矫治后肺动脉压力均可下降至正常范围,肺静脉回流受阻会导致持续肺动肺高压。超声可动态测量TAPVC患者的肺循环压力变化情况,并能准确诊断PVO的存在。

Evaluation pulmonary hypertension of total anomalous pulmonary venous connection by echocardiography

Objective To evaluate pulmonary hypertension of total anomalous pulmonary venous connection(TAPVC) by echocardiography by comparing the results before operation,7 days after post-operation and 3 months after operation and to conclude methods for evaluation of pulmonary hypertension(PH).Methods A total of 65 TAPVC patients were included in the study.The echo were performed before operation,7 days and 3 months after operation.The cardiac structure and function were supervised with 2D echo and tricuspid valve ...
