Stereotactic Radiosurgery (Gamma Knife / CyberKnife-type Treatment)
Stereotactic radiosurgery is not surgery in the traditional sense: hundreds of finely focused radiation beams converge on a target with sub-millimeter precision, delivering a treatment dose to the lesion while sparing surrounding brain. It is performed in one to five outpatient sessions with no incision and no anesthesia.
Dr. Daggubati plans radiosurgery jointly with radiation oncology, and for many patients it is the right alternative or complement to surgery.
Who it is for
- Brain metastases (single or multiple)
- Meningiomas and vestibular schwannomas (small to medium)
- Residual pituitary tumors
- Trigeminal neuralgia
- Spinal metastases
- Arteriovenous malformations
Why we use it
- No incision, no hospital stay
- Treats lesions in deep or eloquent areas
- Multiple lesions in one session
- Can be repeated
How the procedure is done
- A thin-cut MRI and CT are fused for planning.
- A lightweight mask or frame holds the head still.
- Treatment lasts 20–60 minutes per session.
- You go home the same day.
Recovery
Immediate return to activity; fatigue or mild headache is possible. Effects on the tumor develop over months and are followed with MRI.
Risks, stated plainly
Temporary swelling, radiation necrosis (delayed), cranial nerve effects depending on location. Dr. Daggubati reviews the specific risks for your situation in person before any decision is made.
