Using radiosurgery for the treatment of vascular malformations


Radiosurgery aims a precisely focused beam of radiation at the abnormal vessels. The procedure takes several hours of preparation and one hour to deliver the radiation. The patient goes home the same day. After six months to two years, the vessels gradually close off and are replaced by scar tissue. The advantage of this treatment is no incision and the procedure is painless. The disadvantages are that it works best with smaller AVMs and may take a long time to show effect (during which time, risk of haemorrhage exists).
