BACKGROUND Chronic subdural hematoma, a benign illness with established surgical treatment, occasionally presents as an annoying recurrence. In this paper, we assess the role of local inflammation and angiogenesis on the recurrence of CSH by measuring relevant biochemical factors from surgical specimens. METHODS During a 2-year period, a prospective(More)
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)
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 Control of neuropathic pain secondary to spinal cord injury is difficult; microsurgical DREZotomy (MDT) is the currently preferred treatment modality. According to previous reports, traditional MDT has poor outcomes when addressing diffuse (infralesional), thermal, and continuous pain. Here, we report improvements in surgical outcomes in these(More)
A 34-year old man with a past history of hepatocellular carcinoma (HCC) complained of headache and visual disturbance. Neuroimaging revealed a right occipital haematoma with rim enhancement and at operation, a metastasis from the primary malignancy was found. Five months after surgery and subsequent adjuvant therapy, he presented with blindness. On(More)
We report a rare case of skull metastasis from ampulla of Vater adenocarcinoma in a patient with controlled primary neoplasm. This 65-year-old Korean man presented with headache and painful parietal scalp swelling, but he did not show any neurological deficits. Computed tomography revealed an osteolytic mass that invaded and expanded through the skull(More)
OBJECTIVE We investigated predictors of survival and the neurological outcomes of neurosurgical patients who experienced cardiac arrest and received cardiopulmonary resuscitation after being admitted to the neurosurgical intensive care unit. METHODS A retrospective study was conducted of adult patients in the neurosurgical intensive care unit who had(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)
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)
OBJECTIVE In the thoracic spine, insertion of a pedicle screw is annoying due to small pedicle size and wide morphological variation between different levels of the spine and between individuals. The aim of our study was to analyze radiologic parameters of the pedicle morphometry from T1 to T8 using computed tomographic myelography (CTM) in Korean(More)
