Overview
Stereotactic Radiosurgery delivers highly focused radiation beams to treat brain tumors, arteriovenous malformations, or other small neurological lesions.
The technique avoids open surgery, minimizing trauma while accurately targeting abnormal tissue. It is often used when traditional surgery carries higher risk or is not feasible.
Indications and Clinical Applications
Stereotactic Radiosurgery is recommended for tumors, AVMs, and certain functional disorders when precise targeting is essential. Preoperative imaging guides treatment planning.
- Small to medium brain tumors
- Cerebral AVMs: Abnormal tangles of blood vessels in the brain
- Functional neurological disorders such as trigeminal neuralgia
Procedure and Technology Used
The procedure uses Gamma Knife or CyberKnife technology to deliver focused beams of radiation. Patients are immobilized during treatment, which usually takes 1–3 hours.
Recovery and Post-Treatment Care
Patients typically resume normal activities within a day or two. Follow-up imaging ensures effectiveness, and medications may manage transient swelling or symptoms.
Expected Outcomes and Benefits
Most patients experience stabilization or shrinkage of lesions with minimal side effects. Non-invasive nature reduces infection risk and shortens recovery time.
