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。
Objective: To compare the results of digital subtraction angiography (DSA) of cerebral artery stenosis distribution in middle-aged and young patients with cerebral infarction and to analyze the distribution of cerebral artery stenosis. Methods: 100 cases of cerebral infarction admitted to our hospital were divided into 60 cases of middle-aged and young group and 40 cases of elderly group according to different age groups. All patients were given DSA. The incidence of stenosis, stenosis Degree, distribution and seizures and other characteristics were compared. Results: The incidence of extracranial artery and anterior circulation stenosis in the elderly group was significantly higher than that in the middle-aged and young patients, while the lesions in the intracranial artery and the posterior circulation stenosis were significantly lower than those in the middle-aged and young patients Significance of the two groups of patients with severe vascular stenosis were occlusion or even mainly were significantly higher than the same group of mild to moderate stenosis, the difference was statistically significant, and the main site of attack were vertebral artery Open, the two groups of patients with vertebral artery opening rate were significantly higher than the same group of middle cerebral artery MI segment, the beginning of the internal carotid artery incidence, the difference was statistically significant. Conclusion: There are some differences in the distribution of cerebral artery stenosis between young and old patients with cerebral infarction. The former is mainly intracranial cerebral artery disease, while the latter is mainly extracranial cerebral artery disease. Vertebral artery openings, and the degree of stenosis were severe or occluded.
