摘　　要：目的　评价多层螺旋CT血管造影 (MSCTA)在诊断肺动脉栓塞 (PE)中的价值。方法　对 16例临床怀疑有PE的患者行多层螺旋CT血管造影 ,其中 8例发现有肺动脉栓塞 ,5例在溶栓治疗 2 0～ 3 0d后进行了多层螺旋CT血管造影复查。结果　 8例PE患者中发现肺段以上肺动脉 43支发生肺动脉栓塞 ,CT影像表现为肺动脉的完全堵塞、不规则充盈缺损、附壁充盈缺损、轨道征等 ;肺动脉主干的扩张 ;肺段和肺叶的缺血性改变或表现为“马塞克”征。 5例在溶栓治疗后跟踪CT复查 ,4例肺动脉栓塞基本消失 ,1例明显缩小好转。结论　多层螺旋CT血管造影是诊断肺动脉栓塞的一种无创伤性的有效检查方法 ,也是临床判断溶栓疗效的直观检查方法。Objective To evaluate the effectiveness of multiple spiral CT angiography in diagnosis of pulmonary embolism.Methods 16 patients clinically suspected of pulmonary embolism underwent multiple spiral CT angiography.Emboli were found in the 8 patients of all on multiple spiral CT angiography.5 of the patients were reexamined with this method 20 to 30 days after thrombolysis. Results In 8 patients with pulmonary embolism,43 vessels were involved with pulmonary embolism.The presence of pulmonary embolism on CT was seen as a total occlusion,partial filling defect,mural filling defect et al;dilated of pulmonary artery trunk;all signs with deceleration of pulmonary blood or “mosaic sign”. 5 patients were reexamined with this method.The emboli dissoved partly or entirely.Conclusion Multiple spiral CT angiography is a noninvasive and effective method for examining pulmonary embolism.
