16层螺旋CT肺血管造影在肺动脉栓塞诊断中的应用价值

Application of 16 Slice Spiral CT Pulmonary Angiography in Clinical Diagnosis of Pulmonary Embolism

目的:观察16层螺旋CT肺血管造影用于诊断肺动脉栓塞的效果。方法:回顾性总结2015年1月至2016年12月南阳张仲景医院收治的35例行16层螺旋CT肺血管造影的肺动脉栓塞患者的临床资料,并分析检查结果。结果:(1)共发现肺动脉1681支,其中385支(22.90%)表现为不同程度栓塞;(2)直接征象表现为中心型、完全阻塞型等类型的充盈缺损,间接征象主要有肺梗死、肺动脉高压以及心包积液等。结论:16层螺旋CT可有效诊断肺动脉栓塞,能够清晰显现栓塞特点。

Objective To observe the effect of 16 slice spiral CT pulmonary angiography in the diagnosis of pulmonary embolism. Methods In Zhang Zhong-jing hospital, a retrospective analysis was conducted on the clinical data of 35 cases of pulmonary artery embolism as confirmed by 16 Slice Spiral CT pulmonary angiography, and analyzed the results. Results（1） There were found 1681 pulmonary arteries, 385（22.90 %） showed varying degrees of embolism;（2） The direct sign included central and complete occlusion fi lling-defect, the indirect signs included pulmonary infarction, pericardial effusion and pulmonary hypertension etc. Conclusion 16 slice spiral CT can effectively diagnose pulmonary embolism, and can clearly show the characteristics of embolism.
