目的:探讨螺旋CT肺动脉造影(CTPA)在诊断肺动脉栓塞中的诊断价值。方法:对20例肺栓塞回顾性分析CTPA的影像学表现,并进行统计学分析。结果:20例肺栓塞共累及肺动脉238支,其中,中心型充盈缺损(8.0%)、锐角附壁型充盈缺损(18.0%)、钝角附壁型充盈缺损(45.0%)、完全闭塞(19.3%)管腔突然狭窄(9.7%)。间接征象有:“肺少血”征、肺梗死、“马赛克”征、右室增大伴或不伴室间隔偏移、主动脉和(或)右侧叶间肺动脉扩张、胸腔积液等。结论:螺旋CTPA是诊断肺栓塞快速、安全有效、无创的检查方法,在PE的诊断中发挥着重要作用。
Objective: To investigate the diagnostic value of spiral CT pulmonary angiography (CTPA) in the diagnosis of pulmonary embolism. Methods: The imaging findings of CTPA were retrospectively analyzed in 20 patients with pulmonary embolism and analyzed statistically. Results: A total of 238 pulmonary arteries were involved in 20 cases of pulmonary embolism, of which central filling defect (8.0%), acute apical filling defect (18.0%), obtuse apical filling defect (45.0%), complete occlusion ) Sudden stenosis (9.7%). Indirect signs are: “pulmonary” syndrome, pulmonary infarction, “mosaic” sign, with or without ventricular enlargement of the right ventricular septal deviation, aortic and / or right lobe of the pulmonary artery dilatation, pleural product Liquid and so on. Conclusion: CTPA is a rapid, safe, effective and noninvasive method for the diagnosis of pulmonary embolism. It plays an important role in the diagnosis of PE.
