Neuropsychological function and brain arteriovenous malformations: redefining eloquence as a risk for treatment

Risk of endovascular treatment of brain arteriovenous malformations.

BACKGROUND AND PURPOSE Independently assessed data on frequency, severity, and determinants of neurological deficits after endovascular treatment of brain arteriovenous malformations (AVMs) are scarce. METHODS From the prospective Columbia AVM Study Project, 233 consecutive patients with brain AVM receiving > or =1 endovascular treatments were analyzed. Neurological impairment was assessed by...

Treatment of arteriovenous malformations.

We read with great interest the paper by Dawson et al. (1] on combined treatment of arteriovenous malformations (AVMs) by embolization and stereotactic radiosurgery, and we would like to congratulate them for their efforts in the therapeutic approach to these lesions. Although we agree with the concept of using a combined approach, we do not recommend the same technical procedure. As discussed ...

Brain Arteriovenous Malformations: Imaging findings and treatment aproaches

The prognosis and treatment of arteriovenous malformations of the brain

INTRODUCTION Despite the passage of a century and a half since the fi rst description of a brain arteriovenous malformation (AVM) (Rokitansky 1846), and although the imaging of brain AVMs advances relentlessly (Fig. 1), we still need adequate studies of brain AVM prognosis and reliable evaluations of their treatment. Prospective, populationbased studies of brain AVM prognosis are underway (Al-S...

Long 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...
