To overcome long-term complications of hemispherectomy, We modified its operative method. The modified hemispherectomy was performed for 31 patients between 1985 and 1992. These patients were studied for 7 years after operation. The results showed total control of seizures in 28 children with chronic epilepsy (90%) or near-total control in the others. No deaths or delayed complications were noted but improvement in behavior and hemiplegia. CT and MRI showed marked shift of the remaining hemisphere. On brain-stem auditory evoked potentials, the latency of peak I was not variant (P > 0.05). The method makes the insulation of the subdural cavity from the ventricular system more reliable, and climates the pathological conditions.
为克服大脑半球切除术的长期并发症，我们改进了其手术方法。1985年至1992年间，对31例患者实施了改良大脑半球切除术。术后对这些患者进行了7年的研究。结果显示，28例慢性癫痫患儿的癫痫发作得到完全控制（90%），其他患儿接近完全控制。未发现死亡或延迟性并发症，但行为和偏瘫有所改善。CT和MRI显示剩余半球有明显移位。脑干听觉诱发电位显示，I波峰潜伏期无变化（P>0.05）。该方法使硬脑膜下腔与脑室系统的隔离更可靠，并改善了病理状况。
