Complications of the Gamma Knife
Archives of Otolaryngology - Head and Neck Surgery, 1996Radiosurgery, originally described by Leksell1in 1951, describes the method of focusing multiple beams of radiation on an intracranial target. Many methods can be used to deliver the radiation, regardless of its source. Leksell developed the method of using multiple fixed cobalt sources for radiation. This system was called a "gamma knife," although no

Gamma Knife Radiosurgery in Children
Pediatric Neurosurgery, 200852 pediatric patients were treated with radiosurgery at the University of California, San Francisco. Arteriovenous malformations were treated in 27 patients. Complete obliteration was noted in 4 of 12 patients imaged more than 2 years after radiosurgery. Arteriovenous malformation rebleed was noted in 1 patient.

To the Editor. — The November 4 letter by Dr Kjellberg 1 criticizing a previous letter comparing radiosurgery using the gamma knife with proton beam therapy was itself misleading. For instance, Dr Kjellberg belittled gamma knife therapy for arteriovenous malformations by equating it to previously unsuccessful treatment by conventional cobalt ...

The first Gamma Knife used helmets containing collimators of different diameters that increase the flexibility of the treatment. Changing these helmets was time-consuming and tedious. The original model that was introduced into the United States was the U model where the patient was inserted into the machine inward and upward, using hydraulics.

Gamma Knife surgery for neurocytoma
Journal of Neurosurgery, 2007Object Although considered benign tumors, neurocytomas have various biological behaviors, histological patterns, and clinical courses. In the last 15 years, fractionated radiotherapy and radiosurgery in addition to microsurgery have been used in their management.

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 of Meningiomas
Stereotactic and Functional Neurosurgery, 1992Fifty 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 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.

Cost Accounting the Gamma Knife
Stereotactic and Functional Neurosurgery, 1993The cost of the three dominant technologies for delivering radiosurgery to the brain are compared. Included in the analysis is the cost of the equipment and labor costs for each procedure. Once a unit is treating more than 100 patients per year the Gamma Knife becomes the most cost-effective technology by a factor of almost 100%.
