摘　　要：目的通过对脑动脉狭窄患者进行肠系膜上动脉CDFI超声成像,分析肠系膜上动脉与脑动脉狭窄的关系。方法采用彩色多普勒超声仪对30例正常老年人和30例脑血管供血不足的老年人的SMA血流情况进行观测,同时行脑动脉DSA造影进行对比分析。观察:①肠系膜上动脉硬化狭窄病变范围与脑动脉硬化狭窄的关系;②脑梗死患者中肠系膜上动脉狭窄者分布的特点。结果有脑血管供血不足的老年人的SMA的血流量和血管直径比正常老年人相应参数明显减小,收缩峰值流速(PSV)、舒张末期流速(EDV)、搏动指数(PI)和阻力指数(RI)明显增大(P<0.05);脑动脉损害越严重,肠系膜上动脉血流动力学改变越严重。结论老年人脑动脉与肠系膜上动脉病变之间有紧密相关性,脑动脉损害越严重,肠系膜上动脉损害越严重,应重视脑血管供血不足的老年人并发肠缺血的存在。Objective To study on the relationship between hemodynamics of superior mesenteric artery and cerebrovas- cular stenosis in the elder. Methods Hemodynamics of superior mesenteric artery of 30 aged healthy people and 30 aged people with cerebral blood supply impaired were studied with color Doppler ultrasound and compared with cerebral angiog- raphy. We observed the following contents： （1） the relationship of stenosis between superior mesenteric artery and cerebro- vascular atherosclerosis; （2） the same risk factors for superior mesenteric artery and cerebrovascular atherosclerosis. Re- sults In the aged people with cerebral blood supply impaired, SMA＇s blood flow volume and the diameter were signifi- cantly less （ P 〈0.05） and the PSV, the EDV, the PI, the RI were significantly greater （ P 〈0.05） than the mean val- ues of the aged healthy people. The severer the damage of coronary artery, hemodynamics of superior mesenteric artery was severer. Conclusion The cerebrovascular atheroselerosis are strongly associated with superior mesenteric arterial le- sions in the aged patients, the severer the damage of cerehrovascular atherosclerosis, the damage of superior mesenteric ar- tery is severer. So we should think highly of ischemia of intestine in cerebral blood supply impaired patients.
