本病常见于老年患者,国内文献报告不多,至今据不完全统计共有23例,以50岁以上为多见。病变系由于小脑后下动脉循环障碍,引起延髓外侧部脑组织软化所产生的一组综合征,故亦称延髓背外侧综合征。自1872年ПpycT氏等曾先后报告过类似小脑后下动脉血栓形成的病例,然而典型的病例是在1895年由Wallenberg氏作出完整的报告,故此综合征亦称为Wall-enberg氏综合征。以后在外国文献中,便有零星的病例报告出现,在国内文献中,1949年报告1例,1956年张,陈二氏报告2例,1958年王、刘二氏报告4例,1960年吴、张二氏报告6例,1962年王、秦二氏报告10例,至今国内文献报告据不完全统计共有23例,可以相信,其实际病例定超过此数。本病常见的原因为动脉硬化、
The disease is common in elderly patients, the domestic literature reports are not so far, according to incomplete statistics a total of 23 cases, more than 50 years of age is more common. Lesions due to circulatory disorders of the posterior inferior cerebellar artery, causing medulla oblongata brain tissue arising from a group of syndrome, it is also known as medullary dorsolateral syndrome. Since 1872 ПpycT et al have reported cases of posterior subclavian artery thrombosis, but the typical case was fully reported by Wallenberg in 1895, so the syndrome is also known as Wall-enberg’s syndrome. Later in the foreign literature, there were sporadic case reports. In the domestic literature, 1 case was reported in 1949, 2 cases were reported by Zhang and Chen Er in 1956, 4 cases were reported by Wang and Liu in 1958, and in 1960, Wu , Zhang Er’s report of 6 cases, 1962 Wang Qin Qin’s report of 10 cases, according to incomplete statistics of domestic literature so far a total of 23 cases, we can believe that the actual case set more than this number. The common cause of this disease is atherosclerosis,
