[Radiosurgery of cerebral arteriovenous malformations: target definition strategy].
OBJECTIVE
Description and critical review of our procedure of definition of the target of irradiation of a cerebral arteriovenous malformations.


METHODS
and method. Fixation of the stereotactic frame, performing of stereotactic angiography and CT scanner were described, and the target including nidus and venous collectors of the a cerebral arteriovenous malformations defined.


CONCLUSIONS
The use of several three-dimensional imaging techniques can improve and simplify the method of delineating target with a reduction of radio-induced complications.
