摘　　要：目的探讨多层螺旋CT肺血管造影(MSCTPA)诊断肺小动脉栓塞的价值,提高对肺栓塞CTPA表现的认识。方法对35例临床疑为肺栓塞的患者行螺旋CT血管造影,其中3例在溶栓治疗后进行复查。结果10例患者,均位于肺动脉的段及亚段以下水平,肺段及亚段肺动脉受累160支。MSCTA显示肺小动脉栓塞的征象为肺动脉内的不规则充盈缺损及完全阻塞,其中栓塞表现为中心型充盈缺损48支、偏心性充盈缺损24支、附壁型充盈缺损21支、完全闭塞型67支。结论MSCTPA能对肺小动脉栓塞作出诊断,对临床正确诊断及治疗后随防有重要意义。Objective To investigate the value of multi-slice spiral CTPA in diag - nosing small pulmonary embolism. Methods 35 Patients of clinically suspected PE underwent spiral CT angiography.3 the patients were reexamined after thrombolysis. Results 160 Pulmonary arteries and their vessels in 10 cases were involved in PE, all of which located in segment and sub-segment of pulmonary arteries. The PE signs of MSCT angiography were irregular filling defect and completed occlusion in the pulmonary artery, including central filling defect（n=48）, eccentric filling defect（n=24）, mural thrombi（n=21） and completed occlusions（n=67）. Conclusion MSCTPA is an id - eal method in diagnosing small pulmonary embolism. It is valuable for clhlical diagnosis and assessment of prognosis.
