【摘要】：目的探讨超声心动图评估完全型肺静脉异位连接(TAPVC)中肺静脉病变的价值。方法收集55例TAPVC患儿的超声心动图资料,并与CTA及术中所见进行对比。结果应用超声心动图根据肺静脉引流部位对55例TAPVC患儿进行分类,分为心上型24例、心内型20例、心下型7例及混合型4例。15例垂直肺静脉梗阻中,心上型的梗阻多出现在垂直静脉与无名静脉或上腔静脉之间,心下型的梗阻均出现在垂直静脉与肝静脉或门静脉之间。肺静脉狭窄4例,其中3例局限性狭窄均为心内型,出现在分支肺静脉与共同肺静脉腔或右心房之间,1例弥漫性狭窄为心下型。分支肺静脉异常9例,其中超声心动图仅检出1例,而CTA检出8例。结论超声心动图能对TAPVC中的肺静脉的引流、梗阻和分支肺静脉近端的狭窄做出更为全面的评价。CTA评估分支肺静脉的汇入和数目异常及远端肺静脉的成像方面优于超声心动图。
[Abstract]:Objective to evaluate the value of echocardiography in evaluating pulmonary venous lesions in complete pulmonary venous ectopic junction (TAPVC). Methods Echocardiographic data of 55 cases with TAPVC were collected and compared with CTA and intraoperative findings. Results 55 cases of TAPVC were classified by echocardiography according to the location of pulmonary venous drainage, including 24 cases of supracardiac type, 20 cases of intracardiac type, 7 cases of subcardiac type and 4 cases of mixed type of vertical pulmonary vein obstruction. The obstruction of the supracardiac type is between the vertical vein and the unnamed vein or the superior vena cava, and the obstruction of the subcardiac type is between the vertical vein and the hepatic vein or the portal vein. In 4 cases of pulmonary vein stenosis, 3 cases of localized stenosis were intracardiac type, and 1 case of diffuse stenosis between branch pulmonary vein and common pulmonary vein cavity or right atrium was subcardiac type. Only 1 case was detected by echocardiography and 8 cases by CTA. Conclusion Echocardiography is superior to echocardiography in the evaluation of pulmonary venous drainage, obstruction and proximal stenosis of branch pulmonary vein in TAPVC. CTA is superior to echocardiography in evaluating the inflow and abnormal number of branch pulmonary veins and the imaging of distal pulmonary veins.
