摘要
目的：探讨64层螺旋CT在法洛四联症及其伴发畸形诊断中的临床应用价值。方法：对21例法洛四联症患者CT资料进行回顾性分析，与手术或心血管造影结果对照。所有病例均行64层螺旋CT检查，并进行多平面重建和容积再现等三维重建。21例患者均行超声心动图检查。14例有手术结果，7例经心血管造影证实。结果：64层螺旋CT对21例患者均显示了肺动脉狭窄、室间隔缺损、主动脉骑跨及右室壁肥厚。合并畸形包括动脉导管未闭6例，右位主动脉弓4例，双主动脉弓2例，永存左上腔静脉7例，迷走左头臂静脉3例，单支冠状动脉1例和大的主肺侧支动脉3例。结论：64层螺旋CT及三维重建不仅显示了心脏的解剖畸形，还清晰显示了冠状动脉及肺动脉的发育情况。64层螺旋CT是一种诊断法洛四联症的重要检查方法。
Abstract
Objective: To evaluate the role of 64-slice CT in the diagnosis of tetralogy of Fallot and accompanied anomalies. Methods: Twenty-one patients diagnosed as tetralogy of Fallot by 64-slice CT were analysed retrospectively. Toshiba Aquilion 64 was used, slice thickness 0.5mm, overlap 0.3mm. Multi-planar reconstruction(MPR), curved-planar reconstruction(CPR), volume render(VR), maximum intensity projection(MIP) and minimum intensity projection(MinIP) were performed in all patients. Meanwhile, ultrasound echocardiography(UCG) was performed on all patients. Fourteen patients were confirmed by operation, 7 by angiocardiography(ACG). Results: Twenty-one patients were diagnosed by 64-slice CT accurately: pulmonary stenosis, ventricular septal defect, overriding of the aorta and hypertrophy of right ventrical were seen. In the 21 patients, 6 patients had patent ductus arteriosus, 4 right aotic arch, 2 double aortic arch, 7 left superior vena cava, 3 aberrant left brachiocephalic vein, 1 single coronary artery, 3 major aorta-pulmonary collateral arteries. Conclusion: 64-slice CT with 3D reconstruction not only show the anatomical structure of the heart, but also show the coronary and pulmonary arteries. 64-slice CT was an important noninvasive method in the diagnosis of tetralogy of Fallot.
