Abstract

Two patients presented with acute subarachnoid hemorrhage from a ruptured intracranial aneurysm. Both patients were treated via endovascular coil embolization, and both developed delayed lower extremity monoparesis without associated symptoms that resolved over the ensuing months. An extensive work-up lead us to propose the following hypothesis: the painless peripheral neuropathy likely resulted from nerve root irritation from abundant subarachnoid blood in the lumbar cistern.

摘要

两名患者因颅内动脉瘤破裂出现急性蛛网膜下腔出血。两名患者均接受了血管内弹簧圈栓塞治疗，且均出现了延迟性下肢单瘫，无相关伴随症状，在随后的几个月内症状缓解。全面的检查使我们提出以下假设：无痛性周围神经病变可能是由于腰池内大量蛛网膜下腔血液对神经根的刺激所致。
