The purposes of this article are to describe the technical factors in performing 64-MDCT of pulmonary atresia with ventricular septal defect (PA-VSD), to describe the anatomic variations in pulmonary arterial circulation and other associated anomalies, and to describe the postoperative evaluation of this condition.
The management of this complex condition has been largely determined by the morphology of pulmonary arteries and the extracardiac sources of pulmonary blood supply. Although echocardiography and catheter angiography are the traditional imaging techniques used to diagnose PA-VSD, 64-MDCT has become a valuable noninvasive imaging technique in comprehensive evaluation of this condition.
本文旨在描述肺动脉瓣闭锁合并室间隔缺损（PA-VSD）患者行 64 层 MDCT 检查的技术要点，描述肺动脉循环的解剖变异和其他相关畸形，并描述该病症的术后评估。
这种复杂病症的治疗方法在很大程度上取决于肺动脉的形态和肺血的体外来源。虽然超声心动图和导管血管造影术是诊断 PA-VSD 的传统影像学技术，但 64 层 MDCT 已成为该病症综合评估的一种有价值的无创影像学技术。
