Transcript of Stereotactic Radiosurgery
By Lisa Rosenberg
Discovered in 1950 by Lars Leksell and Börje Larsson
Noninvasive procedure Uses precise radiation to attack cells Similar to MRI and CT scans Plan mapped out ahead of time Frame fixed to skull
Radiation shrinks tumors Shrinks at the same rate of growth Outpatient Procedure Painless Claustrophobia Common Side Effect
◦ Swelling Rare Side Effects
◦ Nausea◦ Seizures◦ Irritation
Extremely Rare◦ Visual or Hearing loss
Cyclotron – Particle Beam (Proton)◦ Movement◦ Over $100 million
Ordinary modified Linear Particle Accelerator◦ Moving Machine◦ Arcs cross to target one point◦ Over 3.5 cm
Cobalt – 60 (Photon)◦ Gamma Knife◦ 201 cobalt sources◦ Under 3.5 cm
Arteriovenous Malformations Brain Tumors
◦ Benign◦ Malignant◦ Metastatic
Doesn’t Remove Tumor◦ Distorts the DNA
Functional Disorders◦ Trigeminal Neuralgia◦ Deep Cluster Headaches◦ OCD
Little Research on Differences Between Machines
Deep Cluster Headaches◦ High relapse rates
OCD◦ Placebo Effect
Covered by Health Insurance, MMO’s, PPO’s and Medicaid◦ Little as $100
Without Insurance◦ $12,000 - $55,000 for everything
Continuing Trials Better Option for Many Individuals
◦ Less Risk◦ Low Cost◦ Less Time
