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, usi...

BACKGROUND AND PURPOSE The morbidity from spontaneous hemorrhage of untreated brain arteriovenous malformations (AVM) is not well described. METHODS The 241 consecutive AVM patients (mean age 37+/-16 years, 52% women) from the prospective Columbia AVM Databank initially presenting with hemorrhage were evaluated using the Rankin Scale (RS) and the National Institute of Health Stroke Scale (NIH...

BACKGROUND AND PURPOSE The goal of this work was to determine the effect of age at initial presentation on clinical and morphological characteristics in patients with brain arteriovenous malformation (AVM). METHODS The 542 consecutive patients from the prospective Columbia AVM database (mean+/-SD age, 34+/-15 years) were analyzed. Univariate statistical models were used to test the effect of ...

Avian vacuolar myelinopathy (AVM) was first recognized as a cause of bald eagle (Haliaeetus leucocephalus) mortality in 1994 in Arkansas (USA) and has since caused over 90 bald eagle and numerous American coot (Fulica americana) mortalities in five southeastern states. The cause of AVM remains undetermined but is suspected to be a biotoxin. Naturally occurring AVM has been limited to wild water...

BACKGROUND Idiopathic inflammatory myopathy (IIM) is a group of autoimmune diseases with systemic myositis which may involve the myocardium. Cardiac involvement in IIM, although often subclinical, may mimic clinical manifestations of acute viral myocarditis (AVM). Our aim was to investigate the usefulness of the combined analysis of cardiovascular magnetic resonance (CMR) T1 and T2 mapping para...

OBJECTIVES To compare the risk of epileptic seizures in adults during conservative management or following invasive treatment for a brain arteriovenous malformation (AVM). METHODS We used annual general practitioner follow-up, patient questionnaires, and medical records surveillance to quantify the 5-year risk of seizures and the chances of achieving 2-year seizure freedom for adults undergoi...

Arteriovenous malformation (AVM) is a congenital lesion commonly associated with intracranial hemorrhage. We describe a woman with an AVM (Spetzler-Martin grade V) and presenile progressive dementia. The association between AVM and cognition is discussed.

Background: Occipital arteriovenous malformations (AVMs) are still one of neurosurgery’s most intriguing and challenging pathologies. In this study, we reviewed our series of patients with occipital AVMs admitted in Beijing Tiantan Hospital from June 2013 through January 2015 and attempted to evaluate the risk factors of visual field deficits (VFDs) in these patients at presentation. Methods: F...

PURPOSE To evaluate the changes occurring in spinal aneurysm (SA) size related to modification of endovascularly treated AVMs. METHODS Fourteen patients with an intramedullary AVM and associated SA underwent endovascular treatment of their AVM with particles. Embolization sessions numbered from one to 14 (mean five) in each patient. RESULTS Four patients had SAs with size changes mirroring ...
