Early Experience in Gamma Knife Radiosurgery in Korea = 감마나이프를 이용한 정위적 방사선 수술의 치료 경험

국문 초록 (Abstract)

정위적 방사선 수술이 1951년 처음 소개된 이래 근년에 와서 전산화단층활영, 자기공명영상, 뇌혈관촬영술 등 신경영상학의 발달과 함께 방사선 뇌수술의 분야는 급속히 넓어져가고 있다. 1968년 첫 감마나이프가 만들어진 이래 현재까지 전세계적으로 약 6000명 이상의 환자가 치료를 받았다.
본 서울중앙병원 신경외과학교실에서는 1990년 5월 7일 아시아 최초로 감마나이프가 가동된 이래 현재까지 174명의 환자를 치료하였다.
본 논문에서는 치료한 환자의 수술적응증과 질병분류와 치료방법 및 추적 검사결과를 보고하고자 한다.

다국어 초록 (Multilingual Abstract)

Asan Medical Center has installed the first Korean and Asian 201 Cobalt 60 sources gamma knife for stereotactic radiosurgery of intracranial tumors and arteriovenous malformations. The Unit became operational at the center on May 7, 1990.
In the first 4 months of it's operation, we treated 69 patients. However the unit unfortunately became disabled from heavy flooding on September 11, 1990. The new unit has been operational since May 6, 1991 and we have added 105 more patients to make a total of 174 patients(61 with arteriovenous malformations, 113 with brain tumors : 23 with acoustic neurinomas. 19 with meningiomas, 15 with pituitary tumors, 13 with metastatic tumors, 9 with astrocytomas, 7 with angiographically occult vascular malformations. 6 with seizure disorders who had discrete areas of gliotic changes on neuroimaging studies and 6 with schwannomas. etc)
With accumulated experience of more than 6000 patients world treated with the gamma knife unit and with our own experience obtained in a short period of time, it is accurate to say that the gamma knife radiosurgery offers innovative and effective means to treat various intracranial lesions for selected patients.
