摘　　要：完全型肺静脉异位引流(TAPVC)指全部肺静脉未正常回流至左心房的一类左向右分流型先天性心脏病,约占新生儿先心病发病率的1%-3%,其多变的解剖类型及肺静脉狭窄程度直接影响病人的临床症状、外科修复方式及预后。双源CT(DSCT)因时间及空间分辨率高、明显减低的辐射剂量及强大的后处理功能,能对TAPVC患者异位肺静脉起源、走行路径、连接位置、血管床状态、其他伴发畸形及心腔大小进行详细评估,成为TAPVC术前、术后随访必要的无创性检查。本文现就TAPVC的发生发展、病理生理学改变及在DSCT检查中的影像特征、价值及研究进展做一简要综述。Total anomalous pulmonary venous connection(TAPVC)is a rare congenital heart disease that pulmonary veins drain into a systemic vein or the right atrium rather than the left atrium,occurring in only 1%to 3%of children born with congenital heart defects.There is a wide anatomical variety of venous connections and degrees of pulmonary venous obstruction that affect the clinical symptoms,surgical repair methods and prognosis of patients.Featuring high spatial and temporal resolution,dramatic decrease in radiation dose,excellent image quality,and powerful image post-processing,dual-source computed tomography(DSCT)can evaluate the origin,route,drainage sites,vascular bed status,and other associated malformations of anomalous pulmonary veins and cardiac chamber size in patients with TAPVC in detail,and has been widely used as an essential noninvasive preoperative and postoperative examination in TAPVC patients.In this paper,we review the occurrence and development,pathophysiological changes,imaging characteristics,value and research advance of TAPVC in DSCT.
