Several authors investigated stereotactic irradiation as a treatment modality for intracranial DAVM. Targeting of the lesions may require stereotactic angiography and image fusion with MRI (Guo et al. 

In principle, there are dilferent types of energy sources causing either heat (RFA, laser, and microwave) or cold (cryoablation) and therapies such as ionizing radiation (stereotactic irradiation) or radiosurgery (cyber knife). While RFA is well known and used by many physicians, laser and especially cryotherapy are used only by a few centers due to several drawbacks. All heating techniques have to raise tissue temperatures to 60 to 100° C to cause sufficient coagulation necrosis, while cryotherapy freezes cells to death using tissue temperatures below -20° C.
