A retrospective cohort-matched comparison of conscious sedation versus general anesthesia for supratentorial glioma resection. Clinical article.
Glioma resection under conscious ("awake") sedation (CS) is used for eloquent areas of the brain to minimize postoperative neurological deficits. The objective of this study was to compare the duration of hospital stay, overall hospital cost, perioperative morbidity, and postoperative patient functional status in patients whose gliomas were resected using CS versus general endotracheal anesthesia (GEA). ⋯ Patients undergoing glioma resection using CS techniques have a significantly shorter hospital stay with reduced inpatient hospital expenses after postoperative ICU care.

Case ReportsIntraoperative magnetic resonance imaging-guided tractography with integrated monopolar subcortical functional mapping for resection of brain tumors. Clinical article.
The object of this study was to describe the utility and safety of using a single probe for combined intraoperative navigation and subcortical mapping in an intraoperative MR (iMR) imaging environment during brain tumor resection. ⋯ The monopolar probe can be safely implemented in an iMR imaging environment both for navigation and stimulation purposes during the resection of intrinsic brain tumors. In this study there was a trend toward worsening neurological deficits if the distance from the probe to the CST was short (< 5 mm) indicating close proximity of the resection cavity to the CST. This technology can be used in the iMR imaging environment as a surgical adjunct to minimize adverse neurological outcomes.

Impact of International Subarachnoid Aneurysm Trial results on treatment of ruptured intracranial aneurysms in the United States. Clinical article.
The utilization of endovascular treatment for ruptured intracranial aneurysms is expected to change since the publication of the International Subarachnoid Aneurysm Trial (ISAT) in 2002. The authors performed this analysis to determine the impact of ISAT results on treatment selection for ruptured intracranial aneurysms and associated in-hospital outcomes using nationally representative data. ⋯ The results of the ISAT have been associated with a prominent change in practice patterns related to the treatment of ruptured aneurysms. The cost of hospitalization has increased and the mortality has decreased, presumably due to a larger proportion of patients receiving any treatment and endovascular treatment.

Case ReportsMyelopathy due to intracranial dural arteriovenous fistula: a potential diagnostic pitfall. Case report.
Intracranial dural arteriovenous fistula (DAVF) is rare and potentially life-threatening disease often presenting as vascular myelopathy. The early and proper diagnosis is challenging because the clinical manifestations are related to the distribution of the draining vein, not the fistula site, and imaging findings are similar to demyelinating disease of the spinal cord. ⋯ These symptoms were highly suspicious for transverse myelitis but were caused by an intracranial DAVF. Intracranial DAVF with venous reflux to the brainstem and spinal cord is a rare but important differential diagnosis of progressive worsening myelopathy that is treatment resistant and gives the diagnostic impression of transverse myelitis.

Factors involved in maintaining prolonged functional independence following supratentorial glioblastoma resection. Clinical article.
The median survival duration for patients with glioblastoma is approximately 12 months. Maximizing quality of life (QOL) for patients with glioblastoma is a priority. An important, yet understudied, QOL component is functional independence. The aims of this study were to evaluate functional outcomes over time for patients with glioblastoma, as well as identify factors associated with prolonged functional independence. ⋯ The identification and consideration of these factors associated with prolonged functional outcome (preoperative KPS score ≥ 90, seizures, primary glioblastoma, gross-total resection, temozolomide) and decreased functional outcome (older age, coronary artery disease, new postoperative motor deficit) may help guide treatment strategies aimed at improving QOL for patients with glioblastoma.
