OBJECTIVE Although prophylactic antiepileptic drug (AED) use in patients with aneurysmal subarachnoid hemorrhage (SAH) is a common practice, lack of uniform definitions and guidelines for seizures and AEDs rendered this prescription more habitual instead of evidence-based manner. We herein evaluated the incidence and predictive factors of seizure and(More)
BACKGROUND Extracranial pseudoaneurysm is barely noticed after head injury, and therefore, recognizing such sequels is amenable when there is severe initial injury, unexplained intracranial bleeding, or neurologic sequelae. We report such an unexpected case of intraorbital pseudoaneurysm presenting as delayed intraparenchymal hemorrhage. CASE DESCRIPTION(More)
We study the predictive power of Acute Physiology and Chronic Health Evaluation II (APACHE II) and Simplified Acute Physiology Score II (SAPS II) in neurosurgical intensive care unit (ICU) patients. Retrospective investigation was conducted on 672 consecutive ICU patients during the last 2 yr. Data were collected during the first 24 hours of admission and(More)
OBJECTIVE The purpose of the present study is to assess the possibility of disc regeneration by treatment with adipose-derived stem cells (ADSCs) in a rabbit model of degenerative disc disease, and to evaluate the efficacy of a percutaneous technique for constructing a model of degenerative disc disease in rabbits. METHODS The study sample consisted of 20(More)
Deferoxamine (DFX), a potent iron-chelating agent, reduces brain edema and neuronal cell injury that develop due to the hemolysis cascade. Statins have neuroprotective effects via anti-inflammatory action and increment of cerebral blood flow after intracerebral hemorrhage (ICH). The purpose of this study was to identify the effects of combined DFX and(More)
Unilateral hydrocephalus is a rare type of hydrocephalus caused by germinal matrix hemorrhage–intraventricular hemorrhage (GMH–IVH) in preterm infants. We present a case of posthemorrhagic unilateral hydrocephalus in a preterm infant that was successfully treated with neuroendoscopic fenestration of the foramen of Monro without septostomy. Brain ultrasound(More)
Endovascular coil embolization for unruptured intracranial aneurysms (UIAs) has gained popularity because of its low morbidity and mortality in a short-term context. However, Headache is sometimes brought about or worsened after endovascular treatment, and this complaint may lead to perplexing situations, albeit infrequently. The aim of this study is to(More)
Metabolic syndrome (MetS), well-known risk factor for cardiovascular diseases and ischemic stroke, would be associated with an increased incidence of spontaneous non-lesional intracerebral hemorrhage (ICH) because of some pathophysiologic overlaps between stroke subtypes. The purpose of this study is to identify the associations between MetS components,(More)
OBJECTIVE Various procedures have been introduced for anterior interbody fusion in degenerative cervical disc disease including plate systems with autologous iliac bone, carbon cages, and cylindrical cages. However, except for plate systems, the long-term results of other methods have not been established. In the present study, we evaluated radiologic(More)
OBJECTIVE Post-traumatic cerebral infarction (PTCI) is one of the most severe secondary insults after traumatic brain injury (TBI), and is known to be associated with poor outcome and high mortality rate. We assessed the practical incidence and risk factors for the development of PTCI. METHODS We conducted retrospective study on 986 consecutive patients(More)
