摘　　要：目的提高对异常体动脉(ASA)供应左肺下叶基底段而无肺隔离的诊断和分析能力.方法应用CT三维重建成像技术分析4例ASA供应左肺下叶基底段病例,结合文献进行复习.在PubMed及万方数据库、CHKD期刊全文数据库检索截止至2019年1月的ASA供应肺部的相关文献.结果本组4例患者ASA均起自胸主动脉降段,供应左肺下叶基底段,左肺下叶支气管及其分支未见异常.共检索到中文文献13篇,外文文献45篇,共报道119例患者,绝大部分为个案报道.其中男76例,女43例,男女比例约1.77︰1;发病年龄3d~80岁.ASA起自胸主动脉降段,供应左肺下叶基底段共104例,占总报道例数的87%.结论胸部CT增强扫描结合三维血管重建成像可以明确诊断ASA供应左肺下叶基底段.Ohjective To improve the ability to diagnose and analyze anomalous systemic artery(ASA)supply to the basal segmentsof left lower lobe without sequestration.Methods Four cases were analyzed by CT 3D reconstruction imaging technique and relatedliteratures were reviewed.The literature(up to January 2019)review about ASA supply to lung was performed in PubMed,Wanfangdatabase and CHKD.Results In our four cases,the ASA arising from descending thoracic aorta supplied the basal segments of leftlower lobe with normal bronchial connection.119 cases had been reported in 13 Chinese and 45 foreign literatures,mainly in case report,with an age distribution ranging from 3 days to 80 years.The ratio of male to female was 1.77∶1(76∶43).In 104(87%)cases reported,the ASA originated from descending thoracic aorta and supplied the basal segments of left lower lobe.Conclusion Combined with 3Dreconstruction of angiography,thoracic contrast-enhanced CT scan can diagnose ASA supply to normal basal segments of the leftlower lobe definitely.
