摘要(Abstract):

目的:研究2型糖尿病下肢动脉硬化闭塞症(LEASO)患者病变血管的超声影像学特征。方法:选取血管外科收治的LEASO患者81例,根据患者是否合并糖尿病将患者分为糖尿病组(DM)和非糖尿病组(NDM),比较两组患者动脉斑块的声学特征和形态学特征,同时比较合并与未合并高危因素DM组患者病变血管的影像学特征。结果:DM组出现不规则斑块和斑块钙化的比例显著高于N-DM组(P<0.05),DM组病变血管长度、膝下流出道评分以及TASCⅡ分级为C/D型的病变比例均显著高于N-DM组(P<0.05);吸烟的DM组患者动脉粥样硬化斑块出现高回声、不均质回声、斑块钙化以及出现不规则斑块的比例均显著高于不吸烟的DM组患者(P<0.001),合并高血压病、高血脂的DM组患者斑块声学特征、斑块形态特征与未合并高血压病、高血脂的DM组患者比较差异无统计学意义(P>0.05),合并吸烟、高血压病及高血脂3种血管高危因素的DM组患者与未合并血管高危因素的DM组患者的病变血管长度、TASCⅡ分级、膝下流出道的评分以及C/D型病变比例差异无统计学意义(P>0.05)。结论:2型糖尿病LEASO患者病变血管具有一定的影像学特征。
Objective: To research the ultrasonographic features of patients with type 2 diabetes and arteriosclerosis obliterans of the lower extremities( LEASO). Method: 81 patients with arteriosclerosis obliterans of lower extremity treated by vascular surgery were selected as the research subjects. The patients were divided into diabetes group( DM) and non diabetic group( N-DM) according to whether patients had diabetes or not. The acoustic and morphological characteristics of atherosclerotic plaque were compared in two groups,and the high risk factors of vascular disease and the pathological features of patients with DM were observed. Results: The proportion of irregular plaque and plaque calcification in the DM group was significantly higher than that in the N-DM group( P < 0. 05),and the length of the vessels,the score of the downflow of the knee and the proportion of the TASC II Classification to type C/D in the DM groupwere significantly higher than those in the N-DM group( P < 0. 05). Patients with atherosclerotic plaques showed high echo,heterogeneous echo,plaque calcification and the proportion of irregular plaques in smoking DMgroupwere significantly higher than those in non-smoking DM group( P < 0. 001). There was no significant difference in plaque acoustic characteristics and plaque morphology between patients with hypertension and hyperlipidemia in DMgroup and those without hypertension or hyperlipidemia in DM group( P > 0. 05). There was no statistically significant difference in the length of blood vessel,the TASC II Classification,the score of knee inferior drainage and the propor-tion of C/D lesions between DMgroup and DM group with 3 vascular risk factors including smoking,hypertension and hyperlipidemia( P > 0. 05). Conclusion: The lesions of the patients with type 2 diabetes LEASO have certain imaging features.
