BACKGROUND CONTEXT: A paucity of data exists studying outcomes of patients with syringomyelia undergoing spinal deformity correction. The literature does not stratify patients by syrinx size, which is likely a major contributor to outcomes. PURPOSE: To compare differences in outcomes between patients with large (≥ 4mm) and small syrinxes (< 4mm) undergoing spinal deformity correction. DESIGN: Retrospective review PATIENT SAMPLE: 28 patients (11 with large syrinx [LS, ≥ 4mm] and 17 with small syrinx [SS, < 4mm])...

Subarachnoid hemorrhage (SAH) is a devastating form of stroke. Approximately one in four patients develop progressive neurological deterioration and silent infarction referred to as delayed cerebral ischemia (DCI). DCI is a complex, multifactorial secondary brain injury pattern and its pathogenesis is not fully understood. We aimed to study the relationship between cerebral blood flow (CBF) and neuronal activity at both the cortex and in scalp using electroencephalography (EEG) in poor-grade SAH patients undergoing multimodality intracranial neuromonitoring...

BACKGROUND: Intraoperative neuromonitoring (IONM) through electromyography (EMG) studies has been shown to be a safe, effective way to determine the laterality of the spinal cord and guide electrode placement during spinal cord stimulation (SCS). However, the use of IONM to predict post-operative energy requirements and midline has not been examined and offers a new avenue to streamline programming and device selection. Further, the impact of cerebrospinal fluid (CSF) thickness on intraoperative and post-operative amplitudes is understood but has not been explicitly characterized...

PURPOSE: The risk of neurological injury during vertebral column resection is high. In this study, we investigated the incidence and risk factors for neurological complications when treating spinal deformities by thoracic posterior vertebral column resection (PVCR). METHODS: Between 2008 and 2013, there were 62 consecutive patients (34 female patients and 28 male; the mean age: 16.3 years, range 6-46 years) treated with thoracic PVCR. We retrospectively reviewed the clinical records to obtain demographic and radiographic data, operative time, estimated blood loss (EBL, the ratio between circulating and lost blood), bleeding volume (the lost blood), number of vertebrae fused, number of vertebrae resected, usage of titanium mesh cage, and intraoperative neuromonitoring data...

Background Traditionally, the delivery of dedicated neurocritical care (NCC) occurs in distinct NCC units and is associated with improved outcomes. Institution-specific logistical challenges pose barriers to the development of distinct NCC units; therefore, we developed a consultancy NCC service coupled with the implementation of invasive multimodal neuromonitoring, within a medical-surgical intensive care unit. Our objective was to evaluate the effect of a consultancy NCC program on neurologic outcomes in severe traumatic brain injury patients...

BACKGROUND: Cost effectiveness has become an important factor in the health care system, requiring surgeons to improve efficacy of procedures while reducing costs. An awake craniotomy (AC) with direct cortical stimulation (DCS) presents one method to resect eloquent region tumors; however, some authors assert that this procedure is an expensive alternative to surgery under general anesthesia (GA) with neuromonitoring. OBJECTIVE: To evaluate the cost effectiveness and clinical outcomes between AC and GA patients...

BACKGROUND: A craniotomy with direct cortical/subcortical stimulation either awake or under general anesthesia (GA) present 2 approaches for removing eloquent region tumors. With a reported higher prevalence of intraoperative seizures occurring during awake resections of perirolandic lesions, oftentimes, surgery under GA is chosen for these lesions. OBJECTIVE: To evaluate a single-surgeon's experience with awake craniotomies (AC) vs surgery under GA for resecting perirolandic, eloquent, motor-region gliomas...

Ependymomas are the most common gliomas of the conus and lower cord, with the cervical cord being the second most common location. These tumors can extend upward 3-4 vertebra, and some ependymomas can extend up over 15 segments. Depending on many factors, such as tumor size, lateralization, kyphotic deformity, and lordosis state, there are several posterior surgical options, including laminectomy, laminectomy and lateral mass screw-plate, and laminoplasty. In this study, we discuss a case of intradural intramedullary cervicothoracic ependymoma with long-segmental localization, as well as the general surgical principles of its excision with step-by-step demonstrative figures...
