title: Combined treatment effects after embolization and radiosurgery in high-grade arteriovenous malformations. Case report and review of the literature.
abstract: In recent years the multimodal therapy concept has been established for high-grade intracerebral arteriovenous malformations (AVM). One strategy of a multimodal treatment approach for patients with AVM (Spetzler grade V) is reported. After endovascular embolization, the patient underwent radiosurgical treatment of the remaining nidus with a linear accelerator, after which he developed a left-sided hemiparesis in conjunction with severe edema. Angiographic control 44 months after radiation showed an occlusion of the radiosurgically treated nidus. The remaining nidus could be removed by microsurgery. The combination of embolization and radiosurgery may provoke prolonged edema and permanent neurological deficits due to inflammatory perivascular changes.
