The Edinburgh Cancer Centre AVM pathway
The Scottish national service of stereotactic radiotherapy for benign conditions is based at Western General Hospital in Edinburgh. This national service began in April 2018; however, benign conditions have been treated using linac-based stereotactic radiosurgery (SRS) since 1995 in Edinburgh, initially with Radionics XKnife (Integra LifeSciences, New Jersey), until 2011 when the Novalis linac (Varian Medical Systems, California) with ExacTrac (Brainlab, Germany) and a frameless patient positioning system was implemented.
Arteriovenous malformations (AVM), which come under the remit of the benign conditions national service, are abnormal blood vessels in the brain, with an incidence ~1 in 100,000, prevalence 15-18 per 100,000 which can be managed by surgery, embolisation, SRS or a combination of these.
