完全性肺静脉畸形引流的彩色多普勒超声诊断

Diagnosis of Total Pulmonary Venous Anomalous Connection by Echocardiography and Color Doppler flow Imaging

目的 :探讨彩色多普勒超声诊断完全性肺静脉畸形引流 (TAPVC)的价值。方法 :应用HP2 5 0 0、Angilet5 5 0 0型彩色多普勒超声诊断仪检查 7例TAPVC患者 ,常规行二维超声心动图及彩色多普勒血流显像检查 ,主要观察心腔大小、肺静脉左房开口、房间隔缺损部位、大小及分流方向 ,跟踪扫查共同静脉干的走行及开口部位。结果 :7例TAPVC患者中 ,心上型 5例 (ⅠA1例 ,ⅠB1例 ) ,心内型 2例 (ⅡA1例 ,ⅡB1例 ) ,检查发现本组患者均有右房、右室明显增大 ,左房、左室较小 ;继发孔型房间隔缺损 ;左房内不能探及肺静脉开口 ,在心脏后方探及一粗大管道 (CPV) ,其结果与手术完全一致 ,彩色多普勒超声正确显示TAPVC部位。结论 :应用彩色多普勒超声可确定TAPVC的诊断和分型 ,为制定手术方案提供重要依据。

Objictive:To evaluate the value of echocardiography and color Doppler flow imaging in diagnosing total pulmonary venous anomalous connection(TAPVC).Methods:7 patient of TAPVC were studied by echocardiography and color Doppler flow imaging.Dimensions of the chambers,pulmonary venous connection into left atrium,position of ASD as well as the hemodynamics,track of common pulmonary venous trunk(CPV)were analyzed.Results:seven patient included 5 of the supracardiac type(4 of Ⅰ A,1 of ⅠB),and were confirmed by surgery.Echocardiography and color Doppler flow imaging detdcted no pulmonary venous connection with the left atrium,CPV was located behind LA,secondary ASD,dimensions of RA and RV were increased,and LA and LV were decreased.Conclusions:Echocardiography and color Doppler flow imaging can be used for diagnostic classification of TAPVC,which is important for treatment.
