Moyamoya disease is characterized by progressive cerebrovascular occlusion at the peripheral internal carotid artery and development of abnormal collateral circulation at the cerebral basal region. Although abnormal thrombogenesis, inflammation and autoimmune process might be involved in the etiology, the genetic pathogenesis of Moyamoya disease is still(More)
BACKGROUND We evaluated the efficacy of combined STA-MCA anastomosis and EDAGS using inverted STAGF and STAGP for the treatment of adult MMD. METHODS This study included 8 patients with nonhemorrhagic MMD. There were 6 women and 2 men who were between 23 and 62 years old (mean = 37.8 years) in the sample. The combined surgery was performed on 12 sides in(More)
OBJECTIVE We retrospectively reviewed the pediatric patients with moyamoya disease (MMD) who underwent bypass surgery at our institution to compare the surgical results according to the surgical procedures. PATIENTS AND METHODS There were 24 total patients (age range: 2-15 years; mean age: 8.2 years). Twelve patients underwent(More)
OBJECTIVE The effects on neural proliferation and differentiation of neural stem cells (NSC) of basic fibroblast growth factor-2 (bFGF), insulin growth factor-I (IGF-I), brain-derived neurotrophic factor (BDNF), and nerve growth factor (NGF) were assessed. Also, following combinations of various factors were investigated : bFGF+IGF-I, bFGF+BDNF, bFGF+NGF,(More)
BACKGROUND Cranioplasty is usually performed for aesthetic, protective and patient comfort reasons. The objective of this study is to examine the effects of cranioplasty on the cerebral hemodynamics and cardiovascular system. METHODS Twenty-seven patients who had undergone cranioplasty after extensive skull bone removal to prevent uncontrollable(More)
OBJECT The various terms used to describe subdural fluid collection--"external hydrocephalus", "subdural hygroma", "subdural effusion", "benign subdural collection", and "extraventricular obstructive hydrocephalus"-reflect the confusion surrounding the diagnoses of these diseases. Differentiating external hydrocephalus from simple subdural hygroma may be(More)
OBJECTIVE To evaluate the effects and safety of superficial temporal artery-middle cerebral artery (STA-MCA) anastomosis in the early stage after an acute ischemic event and the improvement of present symptoms in patients with intracranial atherosclerotic occlusive disease with stroke/stroke in progress. METHODS From 2006 to 2010, 20 patients (15 males(More)
OBJECTIVE In the present study, we evaluated the effect, safety and radiological outcomes of cervical hybrid surgery (cervical disc prosthesis replacement at one level, and interbody fusion at the other level) on the multilevel cervical degenerative disc disease (DDD). METHODS Fifty-one patients (mean age 46.7 years) with symptomatic multilevel cervical(More)
BACKGROUND The size of the spinal canal is a factor that contributes to the neurologic deficits associated with cervical OPLL and CSM. We investigate the development of neurologic deterioration after minor trauma and the clinical results of decompressive surgery in cervical spinal stenosis retrospectively. METHOD We treated 200 cases (98 cervical OPLLs(More)
BACKGROUND To clarify the most beneficial treatment of the management modality based on our experience with adult moyamoya disease (MMD). METHODS From 1998 to 2010, clinical results of 142 patients (ischemic, 98; hemorrhagic, 44) with adult MMD were investigated according to management modality. Revascularization surgery (direct, indirect, and combined(More)
