核磁共振成像(MRI)问世前,很多良性的小脑梗塞是不能证实的,小病灶尤其是小脑下半部的病灶,CT 扫描不能发现。然而尸检只能反映最严重病人的临床情况。有了 MRI 的帮助,现在即使是非常小的小脑梗塞也可能发现,而且生前亦能分析它们的局部解剖。为此,作者研究了34例小脑梗塞,分析了供应梗塞区的动脉、神经系统症状和卒中的可能原因。34例中女性9例,年龄56～87岁(平均70.3岁),男性25例,年龄24～78岁(平均63.8岁)。起病后3～7天全部病人做了 MRI 检查和椎基底动脉造影,部分病例检查了心脏超声波。脑梗塞部位和临床表现:小脑后下动脉(PICA)
Before the advent of magnetic resonance imaging (MRI), many benign cerebellar infarction can not be confirmed, small lesions, especially lesions of the lower half of the cerebellum, CT scan can not be found. However, the autopsy can only reflect the most serious patient’s clinical situation. With the help of MRI, even very small cerebellar infarcts can now be found, and their anatomy of the past can be analyzed as well. To do this, the authors studied 34 cases of cerebellar infarction and analyzed the possible causes of arterial, neurological symptoms, and stroke in the infarcted area. Among 34 women, 9 were women aged 56-87 years (average 70.3 years) and 25 were men (range, age, 24-78 years, average 63.8 years). 3 to 7 days after onset, all patients underwent MRI examination and vertebrobasilar angiography, in some cases examined the heart ultrasound. Cerebral infarction site and clinical manifestations: Posterior inferior cerebellar artery (PICA)
