CyberKnife Ablation for Intramedullary Spinal Cord Arteriovenous Malformations (AVMs): A Promising New Therapeutic Approach
Objective: Intramedullary spinal cord arteriovenous malformations (AVMs) are very rare lesions which are characteristically associated with recurrent hemorrhage and progressive ischemia. Although favorable location, size and vascular anatomy make it sometimes possible to manage this condition with embolization and/or microsurgical resection, there are no good treatment options for many, if not ...
متن کاملCyberKnife radiosurgery for spinal neoplasms.
The role of stereotactic radiosurgery for the treatment of intracranial lesions is well established. Its use for the treatment of spinal lesions has been limited by the availability of effective target immobilization and localization technologies. Conventional external beam radiotherapy lacks the precision to allow delivery of large doses of radiation near radiosensitive structures such as the ...
متن کاملDynamic CT angiography for cyberknife radiosurgery planning of intracranial arteriovenous malformations: a technical/feasibility report
BACKGROUND Successful radiosurgery for arteriovenous malformations (AVMs) requires accurate nidus delineation in the 3D treatment planning system (TPS). The catheter biplane digital subtraction angiogram (DSA) has traditionally been the gold standard for evaluation of the AVM nidus, but its 2D nature limits its value for contouring and it cannot be imported into the Cyberknife TPS. We describe ...
متن کاملLong term effects of Gamma knife Radiosurgery for treatment of cerebral arteriovenous malformations
Abstract Background: The Gamma Knife Radiosurgery (GKR) is an established management option for Cerebral Ar-teriovenous Malformations (AVMS). Therapeutic benefits of radiosurgery for arteriovenous malformations are complete obliteration of nidus with minimal neurological deficit. Methods: Radiosurgery was performed between February 2003 and April 2010 at Kamraniye day clinic, Teh-ran, Iran, us...
متن کاملCurrent status of radiosurgery for arteriovenous malformations.
Cerebral arteriovenous malformations (AVM), regardless of the mode of discovery, have an annual risk of hemorrhage of approximately 4 percent. A progressive obliterative vasculitis culminating in the occlusion of an AVM may be induced by the administration of radiation doses of approximately 20 Gy given in a single fraction. The process takes about two years and occlusion occurs in approximatel...
