In the neurosurgical approach to intracranial aneurysms which are often accompanied by arterial spasm and cortical ischaemia, monitoring procedures aim to obtain useful information on cerebral function. SEPs evoked by stimulation of the median nerve at the wrist and of the tibial nerve at the medial malleolus were registered in 45 patients with intracranial aneurysms during neurosurgical procedures. Our results show SEP abnormalities during different stages of neurosurgical procedures in 36 patients out of the monitored 45. Significant abnormalities of SEPs with respect to the control group were decrease of the amplitude of N 20-P 25 complex, lengthening of the absolute latency of the waves N 20- and P 25 and lengthening of the central conduction time (CCT) (N 13-N 20). The greatest SEP abnormalities were registered during the neurosurgical approach to aneurysm and during the clipping procedure. However, the changes were reversible in the majority of the patients. The aim of this paper was to focus on early detection of some cerebral function disturbances during the neurosurgical procedure as well as the prevention of possible brain damage.
在神经外科治疗常伴有动脉痉挛和皮质缺血的颅内动脉瘤时，监测程序旨在获取有关脑功能的有用信息。在45例颅内动脉瘤患者的神经外科手术过程中，记录了刺激腕部正中神经和内踝胫神经诱发的体感诱发电位（SEP）。我们的结果显示，在监测的45例患者中，有36例在神经外科手术的不同阶段出现SEP异常。与对照组相比，SEP的显著异常包括N20-P25复合波振幅降低、N20波和P25波绝对潜伏期延长以及中枢传导时间（CCT，N13-N20）延长。最大的SEP异常出现在神经外科手术接近动脉瘤和夹闭过程中。然而，大多数患者的这些变化是可逆的。本文的目的是关注神经外科手术过程中一些脑功能障碍的早期检测以及预防可能的脑损伤。
