进展性缺血性脑卒中患者头颅MRA特征的研究

Study on MRA of Cerebral Vascular Stenosis in Patients with Progressive Ischemic Stroke

目的探讨进展性缺血性脑卒中(SIP)的发生是否与患者的脑血管狭窄个数、部位等有关。方法整群选取2009年9月—2012年9月该院收治的329例SIP患者为治疗组,同时收集同期非SIP的329例为对照组,通过MRA对患者的脑血管狭窄个数、部位等结果进行研究。结果该研究显示二组患者的脑血管狭窄部位比较在颈内动脉系统差异有统计学意义,P=0.011<0.05;二组患者的脑血管狭窄个数包括狭窄个数1个、2个3个及其以上比较差异无统计学意义,P=0.469>0.05。结论进展性缺血性脑卒中的发生与患者的脑血管狭窄部位有相关性。

Objective To explore whether progressive ischemic stroke(SIP) is associated with the number and location of cerebral vascular stenosis. Methods 329 patients with SIP during September 2009 and September 2012 were assigned to treatment group and other 329 persons without SIP were assigned to control group, and the number and location of cerebral vascular stenosis were observed using Magnetic Resonance Angiography(MRA). Results The study showed that there were more cases of cerebral vascular stenosis in internal carotid artery system in the treatment group than in the control group, and the difference was statistically significant, P= 0.011<0.05; there was no statistically significant difference in numbers of patients who had either 1, 2 or more than3 cerebral vascular stenoses between the two groups, P =0.469 >0.05. Conclusion SIP is associated with the location of cerebral vascular stenosis.
