Stereotactic Radiosurgery
Stereotactic radiosurgery (SRS) is a non-invasive treatment using focussed radiation to treat abnormal blood vessels in the brain without the need for more invasive treatments such as open cerebrovascular surgery or neurointerventional radiology. The radiation is delivered precisely to the abnormal blood vessels which gradually thicken and close off over months to years. The surrounding radiation dose to normal healthy brain is minimised.
