Clinical Significance of Decompressive Craniectomy Surface Area and Side.

Objective: Decompressive craniectomy (DC) can partially remove the unyielding skull vault and make affordable space for the expansion of swelling brain contents. The objective of this study was to compare clinical outcome according to DC surface area (DC area) and side.

Methods: A total of 324 patients underwent different surgical methods (unilateral DC, 212 cases and bilateral DC, 112 cases) were included in this retrospective analysis.

Temperature Difference between Brain and Axilla according to Body Temperature in the Patient with Brain Injury.

Objective: Commonly, brain temperature is estimated from measurements of body temperature. However, temperature difference between brain and body is still controversy. The objective of this study is to know temperature gradient between the brain and axilla according to body temperature in the patient with brain injury.

Laboratory Predictors of Contrast-Induced Nephropathy After Neurointervention: A Prospective 3-Year Observational Study.

Objective: The purpose of this study was to assess the natural course of contrast-induced nephropathy (CIN) and to determine the predictive abilities of preprocedural high-sensitivity C-reactive protein (hs-CRP) and urine neutrophil gelatinase-associated lipocalin for CIN after neurointervention procedures.

Methods: We prospectively enrolled 176 patients who underwent an elective neurointervention procedure (diagnostic angiography or endovascular surgery). CIN was defined as an increase in serum creatinine of more than 0.

A simple prediction score system for malignant brain edema progression in large hemispheric infarction.

Malignant brain edema (MBE) due to hemispheric infarction can result in brain herniation, poor outcomes, and death; outcome may be improved if certain interventions, such as decompressive craniectomy, are performed early. We sought to generate a prediction score to easily identify those patients at high risk for MBE. 121 patients with large hemispheric infarction (LHI) (2011 to 2014) were included.

Microsurgical resection of deep-seated lesions using transparent tubular retractor: pediatric case series.

Background: To facilitate effective resection of deep-seated brain lesions without causing significant trauma to the overlying cortex, the authors used a transparent plastic tubular retractor to approach these lesions.

Methods: Between July 2009 and January 2011, we used an 11-mm diameter transparent plastic tubular retractor in combination with a frameless stereotactic navigation system to remove 18 deep lesions.

Results: Gross total resection of the lesions was achieved in 14 of 18 patients, and subtotal removal occurred in four patients.

Efficacy of endoport-guided endoscopic resection for deep-seated brain lesions.

Surgery for deep-seated brain lesions without causing significant trauma to the overlying cortex is difficult because brain retraction is required to approach these lesions. The aim of this study was to determine the efficacy of endoport-guided endoscopic or microscopic removal for deep-seated lesions using the neuronavigation system. Between October 2008 and December 2009, 21 patients (17 men and 4 women; average age, 40.

Motion-preserving reduction and fixation of C1 Jefferson fracture using a C1 lateral mass screw construct.

The treatment of C1 Jefferson fractures is controversial. Non-surgical treatment with halo fixation always bears the risk of insufficient healing with further instability and increasing neck pain. However, a C1-2 fusion can markedly decrease the rotatory motion of the neck.

The patterns and risk factors of hearing loss following microvascular decompression for hemifacial spasm.

Objective: The aim of this study was to reveal the risk factors including intraoperative brain stem auditory evoked potential (BAEP) changes and to define parameter and warning values of BAEP beyond which the probability of hearing impairment rises significantly.

Methods: From April 1997 to February 2009, 1156 patients underwent microvascular decompression (MVD) for hemifacial spasm (HFS) and their medical records and audiologic data. The intraoperative BAEP monitoring was performed in all operations during surgery from the time of administration of general anesthesia until the time of skin closure.

Treatment modalities and outcomes for asymptomatic meningiomas.

Objectives: The aim of this study is to investigate the outcomes of asymptomatic meningiomas (MNGs) after a variety of treatment modalities, including observation, microsurgery (MS), and gamma knife radiosurgery (GKRS).

Methods: From 1996 to 2008, 154 patients with asymptomatic MNGs were treated, and their medical records and imaging data were retrospectively analyzed. There were 121 females and 33 males with a mean age of 59.

Primary thoracic epidural melanoma : a case report.

A 68-year-old woman with progressive paraparesis and altered sensation lasting approximately five days was admitted to our clinic. Magnetic resonance imaging (MRI) revealed an advanced stage T7-8 epidural mass ventral to the spinal cord, which was believed to be a metastatic tumor considering the patient's age. A highly enhanced epidural mass and pedicle appeared during the MR scan.
