Abstract
The treatment of arteriovenous malformations (AVMs) requires a multidisciplinary management including microsurgery, endovascular embolization, and stereotactic radiosurgery (SRS). This article reviews the recent advancements in the multimodality treatment of patients with AVMs using endovascular neurosurgery and SRS. We describe the natural history of AVMs and the role of endovascular and radiosurgical treatment as well as their interplay in the management of these complex vascular lesions. Also, we present some representative cases treated at our institution.
Highlights
Arteriovenous malformations (AVMs) are relatively rare cerebral lesions that may cause significant neurological morbidity in young people
If the AVM has bled, targeted endovascular embolization of the AVM is recommended in selected cases because it may decrease the risk of hemorrhage and eradicate radioresistant spots of the lesion during the latency period following stereotactic radiosurgery (SRS)
We will review the role of embolization and radiosurgery alone with emphasis on the combined treatment to optimize the eradication of nonsurgical AVMs, as well as the newer fractionated radiosurgical approaches especially designed to treat larger AVMs where a therapeutic plan is not always well defined
