摘要
目的探讨多层螺旋CT(MSCT)肺动脉造影在肺动脉栓塞(PE)诊断中的应用价值。方法抽取2020年9月至2021年10月南阳市第一人民医院收治的经临床综合诊断为PE的106例患者,并根据患者的病情程度分为危重组(70例)与非危重组(36例)。所有患者均有完整资料,均接受过MSCT肺动脉造影检查,总结PE影像学表现、MSCT肺动脉造影诊断结果,以及病情评估结果。结果完全闭塞型、中心型、偏心型PE之间存在影像学差异,其中完全闭塞型多表现为血管截断征,中心型多表现为轨道征,偏心型多表现为低密度充盈缺损。MSCT肺动脉造影可见管腔内栓子,累及动脉共计220处,其中左肺88处,右肺132处;完全闭塞65处,管腔内充盈缺损155处。危重组CT肺动脉栓塞指数、中央肺动脉受累比率均高于非危重组,差异有统计学意义(P<0.05)。结论MSCT肺动脉造影对PE有着不错的诊断价值,可清晰显示病变位置、累及范围与形态,还可了解病变的严重程度,提供更多可靠的依据,从而为临床诊治提供参考。
Objective To investigate the application value of multi-slice spiral computed tomography total of(MSCT)pulmonary angiography in the diagnosis of pulmonary embolism(PE).Methods A total of 106 patients with PE diagnosed by clinical comprehensive examination in the First People’s Hospital of Nanyang from September 2020 to October 2021 were selected.And they were divided into severe group(70 cases)and non-severe group(36 cases)by severity of disease.All selected patients had complete clinical data,and received MSCT pulmonary angiography.The imaging manifestations of PE,the diagnostic results of MSCT pulmonary angiography,and the results of disease assessment were summarized.Results There were significant differences in imaging manifestations of completely occlusive PE,central PE and eccentric PE.Most of completely occlusive PE showed vascular truncation sign;most of central PE showed orbit sign;and eccentric PE showed low density filling defects.Results of MSCT pulmonary angiography showed intraluminal emboli,involving a total of 220 arteries,including 88 lesions locating in left lung and 132 lesions in right lung.Results of MSCT pulmonary angiography showed 65 complete occlusions and 155 intraluminal filling defects.The computed tomography pulmonary artery embolism index and proportion of involved central pulmonary artery of the severe group were higher than those of the non-severe group,and the difference was significant(P<0.05).Conclusions MSCT pulmonary angiography has good diagnostic value in the diagnosis of PE.It can clearly show the location of lesions,involved extent and shape,display the severity of the lesion,and provide more reliable evidence for clinical diagnosis and treatment.
