摘要
目的 评价急性肺动脉栓塞 (APE)螺旋CT (SCT)的诊断价值。材料和方法 对 48例急性肺动脉栓塞进行SCT扫描 ,观察血栓累及部位、表现形式及其它改变。结果 48例均累及两下肺部分或全部段动脉 ,血栓向上延伸 ,36例达中间肺动脉 ,8例达叶动脉 ,2例达主肺动脉。中心肺动脉扩张。结论 急性肺动脉栓塞表现为段动脉以上中心性充盈缺损及肺动脉扩张。
Purpose: To evaluate the effectiveness of SCT in diagnosis of acute pulmonary embolism (APE). Materials and Methods: 48 patients aged from 15～75 years had APE demostrated by SCT. The definiting location, feature and other changes of APE were studied. Results: Among 48 patients with APE, all segmental artery, interlober artery (36), lober artery (8) and main pulmonary artery (2) were seen with SCT. The SCT features of APE were intraluminal filling defect and dilation of central pulmonary artery. Conclusion: The SCT features of APE are intraluminal filling defect from segmental to lober or main pulmonary artery and dilation of central pulmonary artery. SCT plays an important role in clinical diagnosis of APE.
