The CyberKnife Robotic Radiosurgery System improves on other radiosurgery techniques by eliminating the need for stereotactic frames. As a result, the CyberKnife System enables doctors to achieve a high level of accuracy in a non-invasive manner and allows patients to be treated on an outpatient basis. The CyberKnife System can pinpoint an AVM’s exact location in real time using X-ray images taken during the treatment that reference the unique bony structures of a patient’s head.
CyberKnife arteriovenous malformation treatments are typically performed on an outpatient basis with one to five treatments, requiring no overnight hospital stays. Most patients experience minimal to no side effects with a quick recovery time.
A brain AVM (arteriovenous malformation) is an abnormal connection between arteries and veins. An AVM is typically congenital, meaning it dates to birth. An AVM can develop anywhere in your body but occurs most often in the brain or spine. A brain AVM, which appears as a tangle of abnormal arteries and veins, can occur in any part of your brain. The cause isn't clear.
You may not know you have a brain AVM until you experience symptoms, such as headaches or a seizure. In serious cases, the blood vessels rupture, causing bleeding in the brain (hemorrhage). Once diagnosed, a brain AVM can often be treated successfully.
Stereotactic Radiosurgery Treatment (SRS)
CyberKnife Stereotactic Radiosurgery (SRS) delivers radiation in fewer treatments than conventional radiation therapy such as 3DCRT. Tumors that lie outside of the head and neck are more likely to move due to respiratory motion and natural movements of the body. This motion makes it very difficult to precisely deliver high stereotactic doses of radiation to an intended target. CyberKnife SBRT has the unique ability to compensate for these types of movements and effectively deliver radisurgery treatments to very small isolated areas.
