室间隔缺损伴肺动脉闭锁的心血管造影方法及诊断

Angiocardiographictechniqueanddiagnosisofpulmonaryatresiawithventricularseptaldefect

目的：介绍诊断室间隔缺损伴肺动脉闭锁的特殊心血管造影技术。材料和方法：对６６例室间隔缺损伴肺动脉闭锁进行了主动脉造影、选择性体肺循环侧支血管造影和楔入肺静脉造影。结果：在此６６例中，肺动脉血供来源于未闭动脉导管者２４例，来源于体肺循环侧支血管者２６例，来源于细小的生理性侧支血管者１２例，二肺血供来源不同者４例。６６例中两侧肺动脉汇合者４２例。结论：楔入肺静脉造影对某些室间隔缺损伴肺动脉闭锁病例是一种十分有效而颇为安全的诊断手段。
