摘要
目的:探讨完全性肺静脉异位连接(TAPVC)的彩色多普勒超声心动图(CDE)图像特征及超声心动图诊断TAPVC的价值。方法:对16例手术证实的TAPVC患儿进行回顾性分析。结果:TAPVC的CDE具有明显的图像特征:①肺静脉未与左房直接连接;②心上型TAPVC可见肺静脉共腔-垂直静脉-左无名静脉-上腔静脉-右心房或肺静脉共腔-上腔静脉近心端;心内型TAPVC可见四根肺静脉引流入扩张的冠状静脉窦-右心房;心下型TAPVC可见肺静脉共腔-降垂直静脉-肝内门静脉相连;混合型TAPVC以心内型+心上型常见;③均有心房水平(经ASD或PFO)右向左分流。根据TAPVC的CDE图像特征该16例作出正确诊断,诊断准确率100%,引流部位正确率94%。结论:彩色多普勒超声心动图对TAPVC的诊断有很高的临床价值。
Abstract
Objective: To explore the imaging characteristics of total anomalous pulmonary venous connection(TAPVC) in color Doppler echocardiography(CDE). Methods: Data of CDE in 16 patients with TAPVC confirmed by surgery were analyzed retrospectively. Result: The CDE characteristics were as follows: ①the pulmonary veins join to form a confluence channel that drains back to the RA rather than to the LA. ②In the supracardiac form of TAPVC it drains to the left vertical vein, to the innominate vein to the RSVC or drains to the SVC directly. In the intracardiac form of TAPVC it drains to the coronary sinus(CS). In the infracardiac form of TAPVC drains to the descending vertical vein, to the hepatic system. Mixed form of TAPVC occur in which the PV drains to two separate systemic venous sets(left vertical vein and CS). ③Right to left shunt at atrial level. Sixteen cases were accurately diagnosed by CDE imaging with the diagnostic accuracy rate of 100%, connection sites were correctly diagnosed 94%. Conclusion: CDE has important clinical value in detecting TAPVC.
