报告用CO_2激光器切除颅内肿瘤20例,1例蝶骨嵴脑膜瘤手术失败,术后死亡,19例手术成功。术后随访显示,8例因恶性脑瘤复发死亡,5例脑胶质瘤存活,6例良性病变已恢复工作。作者指出,激光手术切除有减少术中出血,切除肿瘤较为彻底,组织损伤少,无感染并发症等优点,但对恶性脑肿瘤不能延长存活期。 The report of CO_2 laser excision of intracranial tumors in 20 cases, 1 case of sphenoid ridge meningioma surgery failed, died after surgery, 19 cases of successful surgery. Postoperative follow-up showed that 8 patients died of recurrent malignant brain tumor, 5 patients had glioma survived, and 6 patients had benign lesion recovered. The authors point out that laser surgery has the advantages of reducing intraoperative bleeding, complete resection of the tumor, less tissue damage, no complications of infection, but malignant brain tumors can not extend the survival period.
