The aim of this study is to determine surgical outcomes and factors affecting seizure outcomes in patients who harbor supratentorial cavernous angiomas presenting with seizures. Sixty patients were classified into the intractable epilepsy group (n=22) and the sporadic seizure group (n=38) and then managed differently in accordance with our guidelines.(More)
The primary objective of this study was to evaluate the safety of early warfarin resumption following burr hole drainage for warfarin-associated subdural hemorrhage (SDH). This prospective, single-arm, single-center trial was conducted from February 2008 to April 2010. Inclusion criteria were premorbid warfarin therapy, subacute or chronic SDH requiring(More)
OBJECTIVE The aim of the present study was to evaluate the usefulness of transcranial motor evoked potential (MEP) monitoring and its impact on morbidity after surgical clipping of unruptured intracranial aneurysms. METHODS Motor outcomes were compared before and after the application of MEP monitoring for a one year period. A total intravenous anesthesia(More)
BACKGROUND AND PURPOSE To evaluate the factors predictive of contralateral progression in children and adolescents with unilateral moyamoya disease (MMD), the authors retrospectively analyzed clinicoradiological findings. METHODS The records of 394 consecutive patients with MMD aged 0 to 17 years were reviewed. Unilateral MMD was defined based on the(More)
Recently, the treatment of intracranial aneurysms entered a new phase due to safe surgical tool such as neurophysiologic monitoring and challenged by endovascular treatment. To determine the safety of clipping surgery in the modern era, we reviewed our experiences of simple unruptured anterior circulation aneurysm surgery which is commonly performed in many(More)
BACKGROUND AND PURPOSE The purpose of this study was to investigate the efficacy and safety of transventricular neuroendoscopic biopsies in pediatric patients with suprasellar tumors. METHODS Twenty-three pediatric patients (12 males and 11 females) with suprasellar tumors underwent transventricular neuroendoscopic biopsy at our institute by a single(More)
BACKGROUND Both basal collaterals (BC) and cortical microvascularization (CM) on angiography have been suggested as moyamoya disease (MMD)-specific findings; however, it is unknown whether the vascular network represents compensatory mechanisms for vascular occlusion or aberrant active neovascularization. METHODS We investigated the grade of antegrade MCA(More)
PURPOSE The aim of this study was to evaluate clinico-radiological outcomes following gamma knife radiosurgery (GKS) for pediatric arteriovenous malformations (AVMs). METHODS The present series included 39 children (3-17 years of age) who underwent GKS for cerebral AVMs between January 2002 and February 2008. Twenty-five patients presented with(More)
Autologous adult human neural stem cells may be used for regenerative cell therapies bypass potential ethical problems. However, stable in vitro expansion protocols and experimental/clinical factors influencing primary cultures need to be further elucidated for clinically applicable techniques. To address these issues, we obtained biopsy specimens from 23(More)
BACKGROUND As regular medical check-ups are becoming more common, the prevalence of asymptomatic moyamoya disease (MMD) is increasing. However, the definition and clinical features are still unclear. The lack of precision has hampered the establishment of guidelines for the management of asymptomatic MMD. The purpose of this study was to define and clarify(More)
