摘　　要：目的探讨左房主静脉(LACV)的MDCT诊断、鉴别诊断及其临床价值,提高其临床认知度。方法回顾性分析2010年9月-2017年9月期间诊断的6例左房主静脉患者的影像学资料,其中男性2例,女性4例,年龄45-72岁(平均53.2±4.0、中位数50.5),均行多排螺旋CT和经胸超声心动图检查。结果经MDCT诊断的6例LACV患者中,左心房和冠状静脉窦连接5例,左上肺静脉与左无名静脉连接1例;其中5例为冠状静脉窦闭锁(CSOA),1例无其他结构性心脏病,因冠状动脉搭桥术后体检发现。CT诊断的6例患者中,超声仅两例提示冠状静脉窦扩张。结论左房主静脉是临床罕见的静脉畸形,可能存在潜在的严重并发症如反常栓塞等,因此提高对LSCV的认识在临床诊治中具有重要的意义,而MDCT对诊断LSCV具有重要的价值。Objective To explore the MDCT diagnosis,differential diagnosis and clinical value of levoatriocardinal vein(LACV),and to improve its clinical value.Methods Retrospectively analyzed the imaging data of 6 patients with LAVC diagnosed between September 2010 and September 2017,including 2 males and 4 females,aged 45-72 years(mean 53.2±4.0,medium The number is 50.5).All patients underwent multi-slice spiral CT and transthoracic echocardiography.Results Of the 6 patients with LACV diagnosed by MDCT,5 cases were connected to the left atrium and coronary sinus,1 case was connected to the left superior pulmonary vein and left innominate vein;5 cases were coronary sinus atresia(CSOA),and 1 had no other structural Heart disease was found due to abnormal physical examination after coronary artery bypass graft.Of the six patients diagnosed by CT,only two cases of ultrasound showed coronary sinus dilatation.Conclusion The LACV is a clinically rare venous malformation,and there may be potential serious complications such as abnormal embolism.Therefore,improving the understanding of LSCV is of great significance in clinical diagnosis and treatment,and MDCT is of great value in the diagnosis of LSCV.
