目的探讨256层螺旋CT血管造影在婴幼儿重症法洛四联症术前诊断中的价值.方法 2008年1月至2010年12月对48例重症法洛四联症婴幼儿术前行256层螺旋CT检查,所有病例均随后在工作站进行分析,用最大密度投影(MIP)、多平面重组(MPR)和容积再现(VR)等方法,同时与经胸超声心动图(TTE)及手术结果对照.结果 CT检查中,发现TTE漏诊动脉导管未闭4例；主动脉缩窄6例；同时CT显示5例(6处)体、肺动脉粗大侧支.48例患儿中,手术证实256层螺旋CT诊断准确47例,TTE诊断准确33例.256层螺旋CT与TTE诊断的准确率分别为97.9％(47/48)、68.8％ (33/48),两种检查方法的诊断准确率比较,差异有统计学意义(P＜0.05).结论 256层螺旋CT可作为婴幼儿重症法洛四联症术前诊断及合理制订手术方案的重要依据.

Objective To approach the value of diagnosis with the 256-slice spiral CT in severe tetralogy of Fallot of infant.Methods From January 2008 to December 2010,48 cases (severe tetralogy of Fallot of infant) were examined with 256-slice spiral CT preoperatively.All cases were then analyzed in workspace with maximum intensity projection (MIP),multiplanar reconstruction (MPR) and volume rendering (VR),while compared with transthoracic echocardiography (TTE) and surgical results.Results CT examination found that TTE misdiagnosis 4 cases of patent ductus arteriosus and 6 cases of aortic coarctation.Meanwhile,CT showed 6 aorta pulmonary collateral arteries in 5 cases.In 48 cases,surgical results confirmed 47 cases by 256-shce spiral CT,while 33 cases by TTE.The diagnosis accuracy rate of 256-slice spiral CT and TTE was 97.9％ (47/48) and 68.8％ (33/48) respectively.There was statistically significant difference of the two inspections in diagnostic accuracy (P ＜ 0.05).Conclusion The inspection of 256-slice spiral CT can benefit the preoperative diagnosis and operation program in severe tetralogy of Fallot of infant.
