【摘要】 目的分析肺静脉异位引流的CT征象,探讨多层螺旋CT在肺静脉异位引流中的价值。方法对12例完全性肺静脉异位引流患者资料进行回顾性分析,与超声心动图和手术结果对照。所有病例均行多平面重建和容积再现等三维重建。12例患者均行超声心动图检查,10例有手术结果,2例行心血管造影。结果在10例有手术结果的病例中,心上型7例,心内型2例,心下型1例。多层螺旋CT对异位引流静脉均给出定位和定性诊断,超声心动图仅诊断5例。2例心血管造影,1例异位引流静脉行程显示不清。结论多层螺旋CT结合三维重建是一种诊断完全性肺静脉异位引流的无创、准确检查方法。更多还原

【Abstract】 Objective To assess the value of multi-slice spiral computed tomography (MSCT) in the diagnosis of total anomalous pulmonary venous connection (TAPVC). Methods A retrospective analysis was conducted in 12 patients with the diagnosis of TAPVC established by MSCT. Multi-planar reconstruction (MPR), curved-planar reconstruction (CPR), volume rendering (VR), maximum intensity projection (MIP) and minimum intensity projection were performed in all the cases, and the results were analyzed in comparison with those of ultrasound echocardiography (12 cases) and surgical findings (10 cases). Cardiovascular angiography was performed in 2 cases. Results In the 10 patients receiving surgical interventions, 7 presented with supracardiac TAPVC, 2 with cardiac TAPVC, and 1 with infracardiac TAPVC. MSCT allowed qualitative diagnosis and identified the location of the lesions in all the 10 surgical patients, whereas echocardiography established the diagnosis in only 5 patients. In the 2 cases undergoing cardiovascular angiography, the diagnosis was established in only 1 case without clear display of the draining vein. Conclusion MSCT combined with 3-dimensional reconstruction provides a noninvasive and accurate means for the diagnosis of TAPVC.更多还原
