一、绪言治疗脑瘤患者的技术进展一直比较缓慢。对于治疗第三脑室和脑基底这些难以接近部位的肿瘤的技术进展更为迟缓。已有一些技术和器械方面的改进,包括可在最小脑收缩量的情况下接近各部位的方法。迄今,神经外科手术显微镜和双极电凝器对顺利地治疗这类疾病仍是必不可少的。然而,仍还有一个特别麻烦的问题没能解决:肿瘤的切除不能吸出。现有的其余肿瘤摘除术,对临近的组织多少有点损伤。近年来,已普遍使用套圈式电手术切割器。采用这种技术对临近生命中枢或敏感组
I. INTRODUCTION The technological advances in treating patients with brain tumors have been slow. The technology for the treatment of tumors that are difficult to reach in the third ventricle and the basal ganglia is more retarded. There have been some technical and instrumental improvements, including approaches that approach each site with minimal brain contraction. To date, neurosurgical microscopy and bipolar coagulators are still indispensable for the successful treatment of such diseases. However, there is still a particularly troublesome problem that can not be solved: excision of the tumor can not be aspirated. The remaining remaining tumor resection is somewhat more damaging to the adjacent tissue. In recent years, the use of ferrule electrosurgical cutters has become commonplace. The use of this technology is close to the life center or sensitive group
