螺旋CT血管造影对肺动脉栓塞的诊断价值

Diagnose of Pulmonary Embolism by Spiral CT Angiography

目的评价螺旋CT血管造影(SCTA)对肺动脉栓塞(PE)的诊断价值。方法对临床疑诊PE的20例患者进行螺旋CT血管造影成像(SCTA).结果20例患者中确诊PE7例。7例PESCTA直接征象:肺动脉主干或分支内混合性、附壁性、中心性充盈缺损。间接征象:局限性肺纹理稀疏,肺动脉高压,右心室增大,胸腔积液等。结论螺旋CT血管造影具有准确、快速、无创性的优点,对肺动脉栓塞的诊断具有广泛应用价值。

Objective To evaluate the value of spiral computer tomography angiography（SCTA） in the diagnosis of pulmonary embolism（PE）. Methods 20 patients with clinically suspected PE underwent SCTA. Results 7 patients were diagnosed to have PE. The CT fenture of 7 PE case included indirect signs ： mixed filling defect, mural idling defect , central filling defect ; The indirect signs included：local oligemia,pulomonary hypertension, enlargement of fight ventricle, pleural effusion. Conclusions SCTA is an accurate, quick and noninvasive method in diagnosis of PE, which can be used widely.
