螺旋CT血管造影对肺动脉栓塞的诊断价值

目的：评价螺旋CT血管造影（SCTA）对肺动脉栓塞（PE）诊断的临床应用价值。方法：对3例临床疑诊PE的患者行SCTA检查，均明确诊断为PE，其中2例在溶栓后进行了复查。结果：3例患者均为右肺动脉主干处血栓形成，分别表现为血管管腔狭窄、截断或附壁性充盈缺损。2例溶栓后栓子有不同程度缩小，1例抗凝后临床症状好转。结论：SCTA是诊断中心性PE准确、无创、有效的检查方法，且可判断溶栓疗效。

Diagnosis of pulmonary embolism by spiral CT angiography

Objective:To evaluate the value of spiral CT angiography in diagnosis of pulmonary embolism (PE).Methods:3 patients suspected of PE underwent spiral CT angiography.All of them were diagnosed to have PE.Two of them were reexamined with this method after thrombolysis.Results:Emboli were found in all 3 patients on spiral CT angiography, the presence of PE was seen as intralumial filling defect, including partial filling defect, mural filling defect and total occlusion.The emboli dissolved partly and entirely after thrombolysis.Conclusion:Spiral CT angiography is an accurate,noninvasive and effective method for detection and follow up of central PE after thrombolysis.
