Medical Management Versus Surgical Bypass for Symptomatic Intracranial Atherosclerotic Disease: A Systematic Review.

Introduction: Intracranial atherosclerotic disease (ICAD) is a major cause of stroke worldwide. The optimal management of patients with symptomatic ICAD is controversial. Therefore, the aim of this systematic review is to compare medical management versus surgical bypass for the treatment of symptomatic ICAD.

External ventricular drain placement in the intensive care unit versus operating room: evaluation of complications and accuracy.

Objective: External ventricular drain (EVD) placement is a common neurosurgical procedure performed in both the intensive care unit (ICU) and operating room (OR). The optimal setting for EVD placement in regard to safety and accuracy of placement is poorly defined.

Methods: A retrospective chart review was performed on 150 consecutive patients who underwent EVD placement at a tertiary care center from January of 2013 to February of 2014.

Chemoprophylaxis for venous thromboembolism in traumatic brain injury: a review and evidence-based protocol.

Venous thromboembolism (VTE) is a recognized source of morbidity and mortality in patients suffering traumatic brain injury (TBI). While traumatic brain injury is a recognized risk factor for the development of VTE, its presence complicates the decision to begin anticoagulation due to fear of exacerbating the intracranial hemorrhagic injury. The role of chemoprophylaxis in this setting is poorly defined, leading to a wide variability in clinical practice.

Treatment resistance mechanisms of malignant glioma tumor stem cells.

Malignant gliomas are highly lethal because of their resistance to conventional treatments. Recent evidence suggests that a minor subpopulation of cells with stem cell properties reside within these tumors. These tumor stem cells are more resistant to radiation and chemotherapies than their counterpart differentiated tumor cells and may underlie the persistence and recurrence of tumors following treatment.
