摘要
目的评价CT肺血管造影(CTPA)在诊断肺动脉栓塞(PE)中的作用。方法对临床怀疑PE经CTP明确诊断的16例患者进行回顾性分析。结果16例患者累及36处肺动脉及其分支。直接征象:部分性充盈缺损;附壁性充盈缺损;中心性充盈缺损即轨道征;完全阻塞。间接征象;局限性肺纹理稀疏,肺动脉高压,右心扩大,胸腔积液,肺梗死灶。结论螺旋CT血管造影对肺栓塞能明确诊断,是安全、无创、快捷的诊断方法。
Objective To evaluate the role of computer tornography pulmonary angiography（CTPA）in the diagnosis of Pulmonary Embolism（PE） .Methods The SCT data of 16 cases of PE suspected by clinical diagnosis were analyzed retrospectively. Results The lesions of 36 pulmonary arteries and branches in the 16 cases were found. CT feature included direct signs and secondary signs, direct signs were found partial filling defect, mural f＇dling defect, central filling defect, namely, railwaytrack signs, total occlusion;secondary signs were found local oligemia, pulmonary hypertension, enlargement of right ventricle and artimn, pleuml effusion and pulmonary infarction. Conclusion CTPA is an accurate method for the diagnosis of PE and it is safe, quick and noninvasive.
