Seminars in Radiation Oncology, 1995
The concept of radiosurgery and its requirements are presented. Dedicated radiosurgical tools include the modified linear accelerators working with a single rotating beam and the Gamma Knife with multiple stationary radiation sources. The 201 gamma beams from the cobalt 60 sources of the Gamma Knife intersect within 0.3 mm and it is possible to align ...

Gamma Knife Radiosurgery for Hemangioblastomas
Stereotactic and Functional Neurosurgery, 1998Thirteen patients (11 males, 2 females) with cerebral hemangioblastomas (HABs) were treated with Gamma Knife radiosurgery (GKR). Four patients had multiple lesions in the brain. The remainder had a single lesion. The total number of lesions was 20. Eight cases had recurrent or residual HABs after surgery.

Complications Following Gamma Knife Radiosurgery
Stereotactic and Functional Neurosurgery, 1995Between May 1992 and February 1994, 213 lesions in 183 consecutive patients were treated with Gamma Knife radiosurgery at Severance Hospital, Yonsei University, Seoul, Korea. During this period, we experienced 2 deaths, 1 directly and another indirectly related to irradiation. Nonfatal complications included 1 tumor bleeding, and 4 ventriculoperitoneal

Gamma Knife Radiosurgery of Meningiomas
Stereotactic and Functional Neurosurgery, 1991Fifty patients with meningiomas were treated during the initial 30 months experience using the 201 source cobalt-60 gamma knife at the University of Pittsburgh. The most frequent site of origin was the skull base. Stereotactic radiosurgery was the primary treatment modality in 16 (32%) patients with symptomatic tumors demonstrated by neuroimaging ...

Gamma knife radiosurgery for craniopharyngiomas
Journal of Neurosurgery, 2000Object. The goal of this study was to elucidate the role of gamma knife radiosurgery (GKS) and adjuvant stereotactic procedures by assessing the outcome of 31 consecutive patients harboring craniopharyngiomas treated between March 1993 and December 1999. Methods. There were 31 consecutive patients with craniopharyngiomas: 18 were men and 13 were women.

Gamma Knife Radiosurgery for Meningioma
2019Since its first reported use in 1976 in Sweden, Gamma Knife (GK) radiosurgery has become an accepted treatment option for intracranial meningioma, either upfront, in combination with planned subtotal resection, or as adjuvant/salvage treatment. Initially, GK was used in patients unfit for a major surgical procedure or for high-risk meningiomas adjacent

Professor Lars Leksell first coupled an orthovoltage X-ray tube with his first-generation guiding device to focus radiation on the Gasserian ganglion to treat facial pain. He subsequently investigated cross-fired protons as well as X-rays from an early-generation linear accelerator (linac) for radiosurgery. In the 1960s, he became dissatisfied with the

Gamma Knife Radiosurgery for Vestibular Schwannomas
Neurosurgery Clinics of North America, 2000Radiosurgery is a surgical procedure associated with minimal functional morbidity and allows patients to return rapidly to their previous level of activity. Most tumors regress in volume with extended follow-up, and the rare occurrence of tumor growth after radiosurgery seems to occur early.

Gamma Knife Radiosurgery for Pituitary Adenomas
Endocrine, 2005Although surgical extirpation by transsphenoidal microsurgery is a major remedy for pituitary adenomas, adjuvant therapy also plays an important role in achieving tumor growth control and endocrine normalization in hormone-secreting tumors. Historically, the treatment options for pituitary adenomas included microsurgery, medical management, and ...
