合并各种颅内损害的血液分流动脉血液进入静脉的现象是众所周知的。不过通常认为临床症状为病变本身引起,而不是局部脑血流量(rCBF)的重新分布。作者报告3例病人的脑血管造影和rCBF研究,他们的症状表现分别为一侧大脑半球内,半球间,从脑进入到肿瘤内有血液动力学的盗血现象。例1、发作性右侧偏瘫和失语,基本上在一周左右恢复,但此后每次过度换气时有发作性失语,锝~(99)脑扫描显示左顶区吸收增加,脑电图在相同区域出现尖波和慢波病灶,左颈内动脉造影证实有顶叶小的动静脉畸形,动脉血供应主要来自一个单独的大脑中动脉大分枝,同时也接受来源于左侧大脑前动脉和其他大脑中动脉分枝的血流。用颈动脉内氙~(133)法测定CBF结果,靠近动静脉畸形的部位和额
It is well known that arterial blood diversion into the vein combined with various intracranial lesions. However, it is generally accepted that the clinical symptoms are caused by the lesion itself rather than the redistribution of regional cerebral blood flow (rCBF). The authors report 3 patients with cerebrovascular angiography and rCBF study, their symptoms were side hemisphere, hemisphere, from the brain into the tumor hemodynamic hemispheric phenomenon. Example 1, paroxysmal right hemiplegia and aphasia, basically recovered in about a week, but after each episode of episodes of aphasia, technetium ~ (99) brain scan showed increased absorption of the left apex, EEG in the same Spike and slow wave regions appear in the area. Left carotid artery angiography confirmed a small parietal arteriovenous malformation. Arterial blood supply mainly came from a separate middle cerebral artery great branch, but also from the left anterior cerebral artery and other Middle cerebral artery branches blood flow. Carotid endarterectomy with xenon ~ (133) method for the determination of CBF results, close to the site and amount of arteriovenous malformations
