Gamma Knife Radiosurgery Treatment & Procedure

Gamma Knife radiosurgery (at times, inaccurately referred to as laser knife radiation surgery) uses high doses of radiation to treat brain pathology, delivered precisely to avoid damaging healthy brain tissue. Gamma knife radiosurgery is able to accurately focus many beams of high-intensity gamma radiation to converge on one or more areas of the brain. Each individual beam in laser knife radiation is relatively low energy, so the radiation has little effect on intervening brain tissue and is concentrated only at the pathology itself.

Published reports indicate that the Gamma Knife procedure may be used as an alternative to standard neurosurgical operations or as an adjunctive therapy in the treatment of residual or recurrent lesions left unresected by conventional surgery. Gamma Knife radiosurgery can be especially useful for those patients who are not suitable for standard surgical techniques due to illness or advanced age. In some neurosurgical cases, the Gamma Knife is the only feasible treatment.

Laser Knife Radiation

Conditions for which Gamma Knife radiation is considered most effective are:

  1. Intracranial tumors such as metastases, acoustic neuromas, pituitary adenomas, craniopharyngiomas, meningiomas, and glial tumors.
  2. Vascular malformations including arteriovenous malformations.

Gamma Knife Radiation Surgery Benefits

  • Gamma Knife is a neurosurgical tool designed exclusively for the treatment of brain disorders.
  • The lesion being treated receives a high dose of radiation with minimum risk to nearby tissue and structures
  • Patients experience little discomfort in laser knife radiosurgery
  • The absence of an incision eliminates the risk of hemorrhage and infection.
  • Hospitalization is short, typically an overnight stay or an outpatient surgical procedure. Patients can immediately resume their previous activities
  • Gamma Knife technology allows treatment of inoperable lesions. The procedure offers hope to patients who were formerly considered untreatable or at very high risk during open skull surgery

Laser Knife Radiation Treatment

Only certain types of problems can be treated by Gamma Knife radiosurgery. Limitations of laser knife radiation procedures include size of the lesion and the nearby presence of critical brain structures. Houston Neurosurgeon Dr. John Park is one of the few neurosurgeons in the area with specialized training in Gamma Knife radiosurgery. Patients who may be a candidate for the Gamma Knife procedure should see him to obtain a consultation. He will determine if you are a candidate for Gamma Knife treatment.
