【摘要】 目的探讨64层螺旋CT对冠状动脉瘘(CAF)的临床应用及诊断价值。资料与方法回顾性分析12例经手术或造影证实的CAF患者的CT资料。男8例,女4例,年龄2～74岁。所有图像均行容积再现(VR)、最大密度投影(M IP)、多平面重组(MPR)和曲面重组(CPR)成像。结果全组病例CAF的起源、行程、引流部位及并发异常均清晰显示,受累冠状动脉表现为走行迂曲、扩张,局部形成动脉瘤4例。单一瘘管11例,单纯起源于左冠状动脉5例,右冠状动脉4例;起源于左右双侧血管3例。多发瘘管1例。引流至右心系统9例、左心系统3例。结论64层螺旋CT可准确显示CAF的起源、行程、引流部位及并发异常,是一种较为理想的无创性诊断CAF的影像方法。更多还原

【Abstract】 Objective To explore the value of the 64-slice computued tomography in diagnosis of coronary artery fistula(CAF).Materials and Methods A total of 12 cases(8 men,4 women;range,2-74 years) proved by operation or angiography with CAF were studied retrospectively.All the data were performed volum render(VR),maximum intensity projection(MIP),muti-planar reconstrction(MPR) and curved-planar reconstrction(CPR).Results The origin,course,drainage of fistula and other cardiac malformation in 12 patients were displayed clearly by 64-slice spiral computed tomography.The coronary arteries involved were distorted and dilated.Aneurysm were demonstrated in 4 cases.The CAF was solitary in 11 patients,and multiple in 1 patient.The fistula orginated from the left,right and both side of heart in 5,4,and 3 cases respectively.The fistula drainaged into the right and left side heart in 9 cases and 3 cases.Conclusion The 64-slice spiral computed tomography displayed the origin,course and the drainage of CAF clearly.It is a relative ideal noninvasive technique in diagnosis of CAF.更多还原
