【摘要】：目的觀察不同類型老年小腦梗死患者的椎-基底動(dòng)脈狹窄情況及其狹窄程度。方法老年小腦梗死患者38例。在患者的MRI圖像上確定小腦動(dòng)脈供血責(zé)任區(qū)并將小腦梗死分為小腦后下動(dòng)脈(PICA)梗死、小腦前下動(dòng)脈(AICA)梗死、小腦上動(dòng)脈(SCA)梗死三種類型。對(duì)38例患者實(shí)施頭頸部CT血管造影(CTA),觀察其椎動(dòng)脈、基底動(dòng)脈是否有狹窄;根據(jù)北美癥狀性動(dòng)脈內(nèi)膜切除術(shù)研究協(xié)助組制定的椎-基底動(dòng)脈狹窄標(biāo)準(zhǔn)判斷椎-基底動(dòng)脈狹窄程度。結(jié)果 38例老年小腦梗死患者中,PICA梗死23例、AICA梗死5例、SCA梗死10例;發(fā)現(xiàn)椎動(dòng)脈狹窄22例、基底動(dòng)脈狹窄5例、椎-基底動(dòng)脈共同狹窄11例。椎動(dòng)脈狹窄、基底動(dòng)脈狹窄、椎-基底動(dòng)脈共同狹窄的患者中,輕中度狹窄者分別為4、2、2例,重度閉塞者分別為18、3、9例;PICA梗死、AICA梗死、SCA梗死的患者中,有椎動(dòng)脈狹窄者分別為18、1、3例,PICA梗死與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,發(fā)生基底動(dòng)脈狹窄者分別為2、1、2例,發(fā)生椎-基底動(dòng)脈共同狹窄者分別為3、3、5例。PICA梗死、AICA梗死、SCA梗死的患者中,椎-基底動(dòng)脈輕中度狹窄的病變血管分別為5、3、5條,重度閉塞的病變血管分別為39、5、10條,PICA梗死與AICA梗死、SCA梗死相比,P均0.05。結(jié)論老年小腦梗死的常見(jiàn)類型是PICA梗死;老年小腦梗死患者常見(jiàn)椎動(dòng)脈狹窄,狹窄程度以重度閉塞為主;PICA梗死患者常見(jiàn)椎動(dòng)脈狹窄,狹窄程度以重度閉塞為主;AICA梗死、SCA梗死患者常見(jiàn)椎-基底動(dòng)脈共同狹窄。
[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.
