中青年与老年脑梗死患者脑动脉狭窄分布的 DSA 分析

目的：比较中青年与老年脑梗死患者脑动脉狭窄分布的数字减影血管造影（DSA）结果，分析脑动脉狭窄分布特征。方法：将我院收治的100例脑梗死患者，按照不同的年龄段，分成中青年组60例与老年组40例，均给予 DSA 检查，对两组患者的脑动脉病变血管狭窄发生率、狭窄程度、分布情况及发作部分等特征进行比较。结果：老年组患者的颅外动脉、前循环狭窄等部位病变发生率显著高于中青年组患者，而颅内动脉、后循环狭窄等部位病变则显著低于中青年组患者，差异存在统计学意义；两组患者的血管狭窄程度均以重度狭窄甚至闭塞为主，均显著高于同组内的轻度、中度狭窄发生率，差异有统计学意义，且主要的发作部位均为椎动脉开口，两组患者的椎动脉开口发生率均显著高于同组的大脑中动脉 MI 段、颈内动脉起始段等发生率，差异有统计学意义。结论：中青年脑梗死与老年脑梗死患者的脑动脉狭窄分布存在一定的差异，前者以颅内脑血管动脉病变为常见，后者则以颅外脑动脉血管病变为主，但均好发于椎动脉开口，且狭窄程度均为重度或闭塞。

Young and middle-aged and elderly patients with cerebral infarction DSA analysis of the distribution of cerebral artery stenosis

Objective to compare the young and middle-aged and elderly patients with cerebral infarction, cerebral artery stenosis of the distribution of digital subtraction angiography (DSA) as a result, analyzing the characteristic of the distribution of cerebral artery stenosis. Methods will our hospital 100 cases of cerebral infarction patients, according to the different age groups, divided into young group of 60 cases with elderly group, 40 cases were performed DSA examination, on two groups of patients with cerebral artery disease incidence, degree of stenosis vascular stenosis, distribution and attack part feature compar-ison. Results in patients with elderly group, the procyclic stenosis of extracranial artery disease incidence is significantly higher than in areas such as the young and middle-aged group of patients, and intracranial artery, posterior circulation narrow lesions were significantly lower than in areas such as the young and middle-aged group of patients, there is statistical significance dif-ference; Two groups of patients with vascular stenosis degree is given priority to with severe stenosis or occlusion, were signifi-cantly higher than in the same group the incidence of mild, moderate stenosis, the difference was statistically significant, and the outbreak of the main parts of vertebral artery opening, the incidence of vertebral artery open two groups of patients were signifi-cantly higher than that of group of middle cerebral artery MI incidence, as well as the internal carotid artery, the difference was statistically significant. Conclusion middle-aged and young cerebral infarction patients with senile cerebral infarction there was some difference of distribution of cerebral artery stenosis, the former is common with intracranial cerebral artery lesions, the latter is given priority to with cranial outside brain artery vascular lesions, but occurs in vertebral artery opening, and the degree of stenosis were severe or occlusion.
