摘要
目的探讨多层螺旋CT对法洛四联症的诊断价值及其临床意义。方法46例经手术病理证实的法洛四联症患者,术前均接受MSCT检查,分析其临床资料及MSCT表现,并与术后结果进行对照。结果MSCT对46例法洛四联症患者均能做出定性诊断。法洛四联症室缺类型:嵴下型室缺44例,嵴上型室缺2例。主动脉骑跨率:骑跨50%为44例,骑跨40%为2例。肺动脉狭窄:46例均有右室流出道狭窄。合并肺动脉瓣二瓣化畸形36例。合并房间隔缺损或卵圆孔未闭14例,动脉导管未闭2例,右位主动脉弓14例,永存左上腔4例,另2例左头臂静脉异常走行。结论MSCT对心外畸形的检出率,肺动脉及段级分支的变异和发育情况有较高的价值。MSCT可以清楚显示冠状动脉起源、走行以及心内畸形。
Objective To evaluate the clinical value of multi-slice CT in diagnosis of tetralogy of Fallot （TOF）. Methods Forty-six patients with pathologically proved TOF underwent CT angiography, the clinic data and MSCT images were analyzed comparing with operation results. Results The type of ventrieular septal defect in 44 patients was perimembranous defect and in 2 patients was crista supraventricularis absent; the degree of aortic overriding.. 44 patients were 50 % and 2 patients was 40%; all the patients were involved with right ventricular outflow tract obstruction and 36 patients were with miscellaneous abnormalities of pulmonary valve, there were 14 patients in association with atrial septal defect or patent foramen ovale, 2 patients with patent ductus arteriosus, 14 patients with right aortic arch, 4 patients with persistent left superior vena cava and 2 patients with left brachiocephalic vena abnormality. Conclusion MSCT was of great value in detecting extra-cardiac structural malformations, and in showing the pulmonary artery development and anomalous coronary artery origin.
