title: [Studying somatosensory evoked potentials for the evaluation of surgical risk in patients operated on for aneurysms of the cerebral arteries].
abstract: In the light of an analysis of 31 patients operated upon in the Neurosurgical Department, Royal Hallamshire Hospital in Sheffield the authors tried to assess the usefulness of somatosensory evoked potentials for evaluating the surgical risk in patients with intracranial aneurysms. The analysed material was chosen so that it could be possible to eliminate the influence of factors connected with the operation on the condition of the patients after the operation. The analysis showed that in patients with low amplitude of N20 potential and prolonged CCT the per cent of insatisfactory operation results may be greater, especially in patients in group III of clinical condition according to the classification of Hunt and Hess (4), and CCT in the analysed group was found to be a slightly worse indicator of surgical risk than the amplitude of N20 potential.
