急性肺栓塞性病变的螺旋CT诊断和评价

Spiral CT Diagnosis and Evaluation for Acute Pulmonary Thromboembolic Disease

目的 评价螺旋CT对急性肺栓塞性病变的诊断价值。方法 对临床怀疑急性肺栓塞性病变经螺旋CT诊断及数字减影血管造影 (DSA)证实的 10例病人作了回顾性分析。观察内容 :胸腔积液的有无及多少 ;肺实质病变的形态、部位及数量 ;中心及周围肺动脉内有无充盈缺损等。结果 肺栓塞 3例 ,肺梗死 7例。除 2例混合型外 ,其余8例均为周围型 ,下叶居多。结论 肺内楔形实变影可提示急性肺栓塞性病变 。

Objective To evaluate the diagnostic value of spiral CT in acute pulmonary thromboembolic disease. Methods Spiral CT scans obstained in 10 patients clinical suspected of having acute pulmonary throboembolic disease were retrospectively. The following were recorded: the presence and size of pleural effusions and the shape, number and location of any parenchymal abnormality according to lobe as well as the presence of any central or peripheral pulmonary intraluminal filling defects. Results 3 patients had CT evidence of pulmonary embolim(PE) and 7 patients had pulmonary infarct(PI).The peripheral emboli were evident in 8 and 2 had cocomitant central and peripheral emboli. Most of them were in low lobe. Conclusion The peripheral wedge shaped opacity may indicate the presence of acute PE, The presence of a vascular sign increases the likelihood that the latter represents PE with infarction.
