【摘要】：目的观察不同类型老年小脑梗死患者的椎-基底动脉狭窄情况及其狭窄程度。方法老年小脑梗死患者38例。在患者的MRI图像上确定小脑动脉供血责任区并将小脑梗死分为小脑后下动脉(PICA)梗死、小脑前下动脉(AICA)梗死、小脑上动脉(SCA)梗死三种类型。对38例患者实施头颈部CT血管造影(CTA),观察其椎动脉、基底动脉是否有狭窄;根据北美症状性动脉内膜切除术研究协助组制定的椎-基底动脉狭窄标准判断椎-基底动脉狭窄程度。结果 38例老年小脑梗死患者中,PICA梗死23例、AICA梗死5例、SCA梗死10例;发现椎动脉狭窄22例、基底动脉狭窄5例、椎-基底动脉共同狭窄11例。椎动脉狭窄、基底动脉狭窄、椎-基底动脉共同狭窄的患者中,轻中度狭窄者分别为4、2、2例,重度闭塞者分别为18、3、9例;PICA梗死、AICA梗死、SCA梗死的患者中,有椎动脉狭窄者分别为18、1、3例,PICA梗死与AICA梗死、SCA梗死者相比,P均0.05;PICA梗死、AICA梗死、SCA梗死的患者中,发生基底动脉狭窄者分别为2、1、2例,发生椎-基底动脉共同狭窄者分别为3、3、5例。PICA梗死、AICA梗死、SCA梗死的患者中,椎-基底动脉轻中度狭窄的病变血管分别为5、3、5条,重度闭塞的病变血管分别为39、5、10条,PICA梗死与AICA梗死、SCA梗死相比,P均0.05。结论老年小脑梗死的常见类型是PICA梗死;老年小脑梗死患者常见椎动脉狭窄,狭窄程度以重度闭塞为主;PICA梗死患者常见椎动脉狭窄,狭窄程度以重度闭塞为主;AICA梗死、SCA梗死患者常见椎-基底动脉共同狭窄。
[Abstract]:Objective to observe the vertebrobasilar artery stenosis and its severity in different types of senile cerebellar infarction. Methods 38 cases of senile cerebellar infarction were studied. The area of responsibility for the blood supply of cerebellar artery was determined on the MRI images of the patients. The infarction was classified into posterior inferior cerebellar artery (PICA) infarction, There were three types of infarction in anterior inferior cerebellar artery (AICA) and superior cerebellar artery (SCA). Results the degree of vertebrobasilar artery stenosis was determined according to the vertebrobasilar artery stenosis standard established in the North American symptomatic arterial endarterectomy group. Results among 38 elderly patients with cerebellar infarction, 23 patients had PICA infarction and 5 had AICA infarction and 10 had SCA infarction. There were 22 cases of vertebral artery stenosis, 5 cases of basilar artery stenosis, 11 cases of vertebrobasilar artery stenosis. Among the 9 patients with severe occlusion, 181patients with vertebral artery stenosis were compared with the patients with AICA infarction and the patients with AICA infarction were compared with each other (P < 0.05). There were 2 cases of basilar artery stenosis and 3 cases of vertebrobasilar artery stenosis. Among the patients with AICA infarction and SCA infarction with PICA, there were 5 vessels with mild to moderate stenosis of vertebrobasilar artery. The pathological vessels of severe occlusion were 39 AICA infarction (P 0.05). Conclusion the common type of senile cerebellar infarction is PICA infarction, and the common vertebral artery stenosis in senile cerebellar infarction patients. The degree of stenosis was mainly severe occlusion and common vertebral artery stenosis in patients with PICA infarction, and common vertebrobasilar artery stenosis in patients with SCA infarction.
