皮层脑电图在单发性海绵状血管瘤手术中的运用

Electrocorticography monitoring in microsurgical treatment of solitary cavernous angiomas

目的:探讨术中应用皮层脑电图(ECoG)监测对提高有癫痫史的海绵状血管瘤手术疗效的作用。方法:对ECoG监测下显微手术治疗的71例有癫痫病史的单发性海绵状血管瘤病例的临床资料进行回顾性分析。结果:71例患者均在ECoG监测下行显微手术,切除病灶及局部癫痫灶;随访58例,其中42例无癫痫发作,13例发作减少90%以上,3例效果不佳。结论:海绵状血管瘤伴有癫痫发作者药物治疗效果不佳,应早期行外科手术治疗。术中ECoG监测对指导手术切除癫痫灶,减少术后癫痫的发作有较大帮助。

Objective To investigate the curative effect of electrocorticography （ECoG） monitoring in the microsurgical treatment of cavernous angiomas. Methods Clinical data of 71 patients with epileptogenic cavernous angiomas, who had been performed ECoG monitoring during the operation, were analyzed retrospectively. Results The foci of cavernous angiomas and epilepsy of the 71 patients were resected during the operation. In the 58 patients who were followed up,42 had not epileptic seizure, and 16 still had epileptic seizure, while the frequencies of 13 patients reduced to below 10% , and 3 patients over 10 %. Conclusion The drug treatment of epileptogenic cavernous angiomas can not control epileptic seizure, and the patients should receive the microsurgical treatment early. Electrocorticography monitoring can direct the surgical procedure, and control the postoperative epileptic seizure.
