Visual evoked potentials were analysed in 15 patients before and after operations performed in the acute and cold periods of rupture of cerebral aneurysms. The analysis made it possible to identify the regions of the disturbed latency and shape of the potentials. The location of the aneurysm determines the site of the region of impairment of the visual evoked potentials, whose area correlates with the severity of the patients' condition in the acute period. Diminution of the region of impairment of the evoked potentials was more manifest in patients who were operated on in the acute period of rupture of the aneurysm than in those who underwent operation in the cold period.
对15例脑动脉瘤破裂急性期和亚急性期手术前后的患者进行了视觉诱发电位分析。通过分析能够确定潜伏期和电位形状受干扰的区域。动脉瘤的位置决定了视觉诱发电位受损区域的部位，该区域面积与患者急性期病情严重程度相关。与在亚急性期接受手术的患者相比，在动脉瘤破裂急性期接受手术的患者诱发电位受损区域的缩小更为明显。
