从动脉瘤而来的栓子可以暂时或永久地引起脑动脉狭窄和阻塞,出现脑部缺血性症状.Teptas和Katsiotis1968年曾介绍此种可能性,并认为蛛网膜下腔出血后引起偏瘫可能是从动脉瘤来的栓子阻塞动脉所致.本文作者报告4例.病例1,35岁妇女,1977年2月入院.入院前2个月病人有过一次左侧肢体无力发作,12小时之内恢复.入院前4周和1周曾有类似发作.腰穿正常.右侧颈动脉造影显示颈内动脉和后交通动脉交界处有一大的动脉瘤.作右额颞开颅术,发现一个2.5×1.5×1.5厘米没有破裂伸向右颞叶的动脉瘤,
Embolism from the aneurysm can temporarily or permanently cause cerebral artery stenosis and obstruction, resulting in cerebral ischemic symptoms. Teptas and Katsiotis described this possibility in 1968 and considered that hemiplegia may occur after subarachnoid hemorrhage. It was caused by an embolus from the aneurysm that blocked the arteries. The authors report four cases. Case 1, 35-year-old woman admitted to hospital in February 1977. Two months before admission, the patient had a left limb weakness attack, 12 hours Internal recovery. There were similar attacks 4 weeks and 1 week before admission. Lumbar puncture was normal. The right carotid angiogram showed a large aneurysm at the junction of the internal carotid artery and the posterior communicating artery. The right frontotemporal craniotomy was found. 2.5 × 1.5 × 1.5 cm without rupture of the aneurysm extending to the right temporal lobe,
