目的 探讨电子束CT(EBCT)在先天性大血管转化诊断中的价值。方法 对20例EBCT诊断的大血管转位进行回顾性分析。所有患者均采用增强单层容积扫描。所有病例均行超声心动图检查。其中5例行心血管造影检查,6例行用手术病理对照。结果 EBCT诊断大血管转位20例,其中完全性大血管转位17例,纠正型大血管转位3例。超声心动图漏诊3例,EBCT在发现并存畸形方面优于超声心动图。结论 EBCT能清晰客观地显示先天性大血管转位的病理解剖形态,对本病有重要诊断价值。
Objective To investigate the value of electron beam computed tomography (EBCT) in the diagnosis of congenital macrovascular complications. Methods 20 cases of EBCT diagnosis of major vessel transposition were retrospectively analyzed. All patients were treated with enhanced monolayer volume scans. All cases underwent echocardiography. Among them, 5 patients underwent cardiovascular angiography and 6 patients underwent surgery and pathology. Results EBCT diagnosis of major vessel transposition in 20 cases, of which 17 cases of complete large vessel transposition, corrected large vessel transposition in 3 cases. Echocardiographic missed diagnosis in 3 cases, EBCT in the detection of coexisting deformity better than echocardiography. Conclusion EBCT can clearly and objectively display the pathological anatomy of congenital large vessel transposition, which has important diagnostic value for this disease.
