ABSTRACT
Radiosurgery (RS) was initiated in Lyon in October 1989. The technique was adapted from that described by Lutz and Saunders in Boston (BRW stereotactic frame). Irradiation is delivered with 18-MV photons produced by a LINAC. From December 1989 to December 1992, 41 patients with arteriovenous malformations were treated by RS; the median age was 33 years. The largest lesion diameter was 11.2-38.5 mm. Fifteen to 20 Gy were delivered on the 70% isodose line. Angiography was performed at 2 years post-treatment in 32 patients demonstrating an overall complete thrombosis rate of 81.3%. This incidence was significantly correlated with the Spetzler and Martin grade before RS (P = 0.0055). Two patients (4.9%) experienced haemorrhage after radiosurgical treatment and one died from an intracerebral-intraventricular haemorrhage. Four patients (9.7%) experienced permanent radiation-induced neurological complications.
