AIM
The aim of this study is the presentation of the imaging findings in patients with pulmonary embolism, the diagnosis of which was made with the use of helical computed tomography.
MATERIAL AND METHODS
The lung CT scans of 14 patients were retrospectively studied. The presence of hypoattenuating thrombus within the lumen of one or more pulmonary arterial branches was considered as the imaging criterion for the diagnosis of pulmonary embolism.
RESULTS
Emboli within the lumen of 1st order branches were found in 2 patients, within the lumen of 2nd order branches in 8 patients, into the lumen of 3rd order branches (lobar) in 10 patients and into the lumen of 4th order branches (segmental) in 6 patients. No emboli were detected in subsegmental or more peripheral branches. Concomitant, secondary findings were the presence of unilateral pleural effusion, areas of pulmonary oligaemia and the presence of a wedge-shaped, pleural-based opacity, indicative of a pulmonary infarct.
CONCLUSION
In conclusion, we were able to make the diagnosis of pulmonary embolism through the direct visualization of intraluminal emboli up until the segmental level, as well as of concomitant, accessory findings of pulmonary embolism.
目的
本研究旨在呈现肺栓塞患者的影像学表现，这些患者的诊断采用螺旋计算机断层扫描。
材料与方法
回顾性研究14例患者的肺部CT扫描。一个或多个肺动脉分支管腔内出现低密度血栓被视为诊断肺栓塞的影像学标准。
结果
2例患者在一级分支管腔内发现栓子，8例在二级分支管腔内，10例在三级分支（肺叶）管腔内，6例在四级分支（肺段）管腔内。在亚段或更外周的分支中未检测到栓子。伴随的次要表现为单侧胸腔积液、肺缺血区域以及出现楔形、胸膜下的实变影，提示肺梗死。
结论
总之，我们能够通过直接观察管腔内栓子直至肺段水平以及肺栓塞的伴随、辅助表现来诊断肺栓塞。
