【摘要】：目的探讨双源CT对单心室(SV)诊断、分型的价值。方法回顾性分析10例经双源CT诊断并经手术、超声等方法证实为SV的病例资料。通过节段分析法分析内脏-心房关系、心房-心室连接、心室-大血管连接等内容,对SV进行分型并确定解剖畸形。结果 10例SV均经双源CT正确诊断,超声诊断正确9例。双源CT对10例SV按心室形态结构分型分为A型8例、B型1例、D型1例,按主动脉与肺动脉位置关系分型分为Ⅰ型1例、Ⅱ型4例、Ⅲ型5例。双源CT确诊合并其他解剖畸形共19种55处。6例接受手术治疗的病例与双源CT结果对比漏诊永存动脉干、下腔静脉肝段缺如、房间隔缺损、动脉导管未闭各1例,误诊房间隔缺损1例。结论双源CT对SV诊断及分型具有重要意义,对外科手术具有重要指导价值。
[Abstract]:Objective to evaluate the value of dual-source CT in the diagnosis and classification of SVV. Methods the data of 10 cases of SV diagnosed by double source CT and confirmed by ultrasound were retrospectively analyzed. Through segmental analysis of viscera atrial relation atrial ventricular connection and ventricular great vascular connection SV was classified and anatomic malformation was identified. Results all 10 cases of SV were correctly diagnosed by dual source CT and 9 cases were diagnosed correctly by ultrasound. Ten patients with SV were divided into type A (n = 8), type B (n = 1), type D (n = 1), type 鈪，
