目的探讨彩色多普勒超声在2型糖尿病患者肠系膜上动脉早期病变诊断中的应用价值。方法2型糖尿病(type 2diabetes mellitus,T2DM)患者87例为T2DM组,同期体检健康者80例为对照组,2组均于口服胃肠造影剂后行彩色多普勒超声检查,测量肠系膜上动脉(superior mesenteric artery,SMA)主干及1、2级分支和肠壁间动脉收缩期峰值血流速度(peak systolic velocity,PSV)、阻力指数(resistance index,RI)、搏动指数(pulsation index,PI),并进行比较。结果 T2DM组SMA主干、1级分支、2级分支和肠壁间PSV分别为(1.289±0.328)、(0.520±0.226)、(0.344±0.143)、(0.256±0.061)m/s,RI分别为0.835±0.045、0.872±0.066、0.691±0.045、0.619±0.080,PI分别为2.995±0.436、2.956±0.506、2.306±0.268、1.701±0.315,明显高于对照组[SMA主干、1级分支、2级分支和肠壁间PSV:(1.078±0.273)、(0.445±0.156)、(0.292±0.134)、(0.204±0.100)m/s,RI:0.660±0.421、0.733±0.070、0.581±0.072、0.516±0.072,PI:2.089±0.702、1.947±0.909、1.985±0.754、1.417±0.453](P<0.05)。结论彩色多普勒超声可用于筛查T2DM患者SMA主干及分支早期血流动力学改变,在T2DM引起的慢性缺血性小肠疾病早期筛查中有重要价值。
Objective To explore the value of color Doppler ultrasound to the diagnosis of early superior mesenteric artery （SMA） lesions in patients with type 2 diabetes mellitus （T2DM）. Methods Eighty-seven patients with T2DM （T2DM group） and 80 healthy volunteers （control group） underwent color Doppler ultrasound examination after taking oral gastrointestinal contrast agent to measure the peak systolic velocity （PSV）, resistance index （RI）, pulsation index （PI） of SMA and its 1- and 2-1eve1 branches and of arteries between intestinal walls, and were compared between two groups. Results PSV levels of SMA and its 1- and 2-level branches and of arteries between intestinal walls were （1. 289±0. 328）, （0. 520±0. 226）, （0. 344±90. 143） and （0. 256±0. 061） m/s, RI levels were 0. 835±0. 045, 0. 872± 0. 066, 0. 69±0. 045 and 0. 619±0. 080, and PI levels were 2. 995±0. 436, 2. 956±4_0. 506, 2. 306±0. 268 and 1. 701±0. 315 in T2DM group, significantly higher than those in control group （PSV： （1. 078 ± 0. 273）, （0. 445 ± 0. 156）, （0.292±0. 134）, （0.204±0. 100） m/s; RI： 0. 660±0. 421, 0.733±0.070, 0. 58±0.072, 0. 516±0. 072;0.516 2±0. 702, 1. 947±0. 909, 1. 985±0. 754, 1. 417±0. 453） （P〈0.05）. Conclusion Color Doppler ultrasound can be used to screen the early hemodynamic changes of SMA and its branches in patients with T2DM, and plays an important role in screening early SMA lesion induced by T2DM.
