The modified adhesive removal (sticky-tape) test is an assessment of somatosensory dysfunction following cerebral ischemia in rats. This test is less time consuming than the original protocol by virtue of requiring minimal pre-training. We present a detailed protocol describing how to conduct the modified adhesive removal (sticky-tape) test. Following right(More)
External ventricular drain (EVD) placement is standard of care in the management of aneurysmal subarachnoid haemorrhage-associated hydrocephalus (aSAH). However, there are no guidelines for EVD placement and management after aSAH. Optimal EVD insertion conditions, techniques to reduce the risk of EVD-associated infection and aneurysmal rebleeding, and(More)
OBJECT Heparin-induced thrombocytopenia Type II (HIT II) is a serious complication that occurs in 0.2-3% of patients treated with heparin and is associated with a high risk of thrombotic events. One center recently reported an incidence of HIT II of 15% in a population of patients with aneurysmal subarachnoid hemorrhage (aSAH). Because these patients are(More)
OBJECT Complex aneurysms of the basilar artery (BA) apex can be successfully treated using surgical occlusion of the proximal BA. Since the introduction of the Guglielmi detachable coil in 1991, the focus on treating BA aneurysms has been on using endovascular techniques. Outcomes with endovascular techniques have been less than optimal for large and(More)
OBJECT Large intracerebral hemorrhage (ICH), compounded by perihematomal edema, can produce severe elevations of intracranial pressure (ICP). Decompressive hemicraniectomy (DHC) with or without clot evacuation has been considered a part of the armamentarium of treatment options for these patients. The authors sought to assess the preliminary utility of DHC(More)
Intracerebral hemorrhage is a devastating neurological illness with few treatment options. In the past 10 years, 6 clinical trials have been completed examining the potential role that putative neuroprotective agents might play in improving outcome. Although each of these trials failed to show a benefit, animal research continues to supply the translational(More)
Brain-computer interfaces (BCIs) are devices that acquire and transform neural signals into actions intended by the user. These devices have been a rapidly developing area of research over the past 2 decades, and the military has made significant contributions to these efforts. Presently, BCIs can provide humans with rudimentary control over computer(More)
OBJECT Intraventricular hemorrhage (IVH) associated with intracerebral hemorrhage (ICH) is an independent predictor of poor outcome. Clinical methods for evaluating IVH, however, are not well established. This study sought to determine the best IVH grading scale by evaluating the predictive accuracies of IVH, Graeb, and LeRoux scores in an independent(More)
INTRODUCTION Exposure to isoflurane gas prior to neurological injury, known as anesthetic preconditioning, has been shown to provide neuroprotective benefits in animal models of ischemic stroke. Given the common mediators of cellular injury in ischemic and hemorrhagic stroke, we hypothesize that isoflurane preconditioning will provide neurological(More)
OBJECTIVE Studies have documented an inflammatory response in the circulating plasma and cerebrospinal fluid of patients with aneurysmal subarachnoid hemorrhage (aSAH). In particular, early upregulation of several complement proteins, including C3a, C4a, and C5b-9, has been demonstrated after the initial hemorrhagic insult. The inflammatory actions of the(More)
