Abstract： 目的评价电子束CT(EBCT)诊断先天性一侧肺动脉缺如的价值.方法对经平片、超声心动图检查后拟诊为肺血管疾病或原发性肺动脉高压的患者行EBCT检查,EBCT诊断先天性一侧肺动脉缺如的11例患者入选,并与超声心动图、核素通气灌注扫描、心血管造影的检查结果作进一步的比较及评估. 结果单发一侧肺动脉缺如4例,均为女性成年人.合并多发心血管畸形7例,其中合并复杂畸形3例,均为男性儿童和左肺动脉缺如;合并单发心血管畸形4例,其中3例为右肺动脉缺如. 结论 (1)儿童时期明确诊断的一侧肺动脉缺如多合并有心血管畸形,且左肺动脉缺如多见,成年人明确诊断的单发一侧肺动脉缺如多为右肺动脉缺如.(2)EBCT对先天性一侧肺动脉缺如的诊断有较高的实用价值,较之多普勒超声更为准确,与心血管造影各具独特优势,但EBCT为无创检查是其特点.
