Stereotactic Radiosurgery for Hemorrhagic Stroke
Treatment of hemorrhagic stroke focuses on controlling the bleeding and reducing pressure in your brain caused by the excess fluid.
Stereotactic radiosurgery is nonsurgical radiation therapy used to repair blood vessel malformations in the brain. It can deliver precisely targeted radiation in fewer high-dose treatments than traditional therapy, which can help preserve healthy tissue.
In stereotactic radio surgery, specialized equipment is used to focus many small beams of radiation on the arteriovenous malformation (AVM) or other target. Each beam has minimal actual effect on the tissue it passes through, but a targeted dose of radiation is delivered to the site where all the beams intersect.
The high dose of radiation delivered to the affected area will cause AVMs to shrink and blood vessels to close off over time after treatment, robbing the malformation of its blood supply. Because of the precise nature of stereotactic radiosurgery, healthy surrounding brain tissue generally remains unaffected.
This procedure is usually performed on an outpatient basis. In most cases, radiosurgery offers a lower risk of side effects when compared with other types of traditional surgical treatments for stroke.
