James Brady, the White House press secretary during President Ronald Reagan's first term in office, was 1 of 4 people (including the President) wounded during an attempted assassination attempt on President Reagan's life on March 30, 1981. John Hinckley, Jr. was found not guilty of this attempt by reason of insanity. The assassination attempt was a ploy by Hinckley, Jr. to impress the actress Jodie Foster. Brady was the most seriously injured of the 4 who were wounded. He suffered a gunshot wound to the left forehead that traveled through the left frontal lobe, corpus callosum, and then into the right frontal and temporal lobes...

BACKGROUND: Antiplatelet medications are usually discontinued before elective neurosurgery, but this is not an option for emergent neurosurgery. We performed a retrospective cohort study to examine whether preoperative aspirin use was associated with worse outcomes after emergency neurosurgery in elderly patients. METHODS: We analyzed all cases of emergency neurosurgical procedures for traumatic intracranial hemorrhage from 2008 to 2012 at a level 1 trauma center...

Measurement of intracranial pressure (ICP) can be invaluable in the management of critically ill patients. Cerebrospinal fluid (CSF) is produced by the choroid plexus in the brain ventricles (a set of communicating chambers), after which it circulates through the different ventricles and exits into the subarachnoid space (SAS) around the brain, where it is reabsorbed into the venous system. If the fluid does not drain out of the brain or get reabsorbed, the ICP increases, which may lead to brain damage or death...

Among the intracranial hematomas, chronic subdural hematomas (CSDH) are the most benign with a mortality rate of 0.5-4.0%. The elderly and alcoholics are commonly affected by CSDH. Even though high percentage of CSDH patients improves after the evacuation, there are some unexpected potential complications altering the postoperative course with neurological deterioration. Poor outcome in postoperative period is due to complications like failure of brain to re-expand, recurrence of hematoma and tension pneumocephalus...

OBJECTIVE: Pipeline Embolization Devices (PED) are commonly used for endovascular treatment of cerebral aneurysms but can be associated with delayed ipsilateral intraparenchymal hemorrhage (DIPH). The role that altered intracranial hemodynamics may play in the pathophysiology of DIPH is poorly understood. We assess middle cerebral artery (MCA) flow velocity changes after PED deployment. MATERIALS AND METHODS: Patients with aneurysms located proximal to the internal carotid artery terminus treated with PED at our institution between 2015 and 2016 were retrospectively reviewed...

<i>Multiple fusiform aneurysms occurring in a single patient are very uncommon. Fusiform aneurysms affecting the anterior circulation are extremely rare and reported cases involve the middle cerebral artery and internal carotid artery. We report here a case of a 55-year-old African American male who had a history of multiple strokes and who was found unresponsive prior to his latest hospital admission. Neuroimaging was remarkable for multiple fusiform aneurysms involving segments of the anterior, middle and posterior cerebral arteries as well as subarachnoid and intraparenchymal hemorrhage...

REVIEW
Isaac Josh Abecassis, Louis J Kim
Chronic subdural hematomas are commonly encountered pathologies in neurologic surgery. Primary management for a symptomatic lesion usually entails surgical intervention. There is controversy regarding ideal modality selection among twist drill craniostomy, bur hole craniostomy, and craniotomy. Variations of the craniotomy include a minicraniotomy (usually defined as 30-40 mm diameter), minicraniectomy, and with or without either a partial or full membranectomy. In addition to medical complications, potential surgical complications include recurrence, seizures, intraparenchymal hemorrhage, and infection...

Intracerebral hemorrhage (ICH) is a life-threatening type of stroke. Previous studies have reported that bone marrow mesenchymal stem cells (BMSCs) may exert beneficial effects on the treatment of ICH. However, it remains unknown whether the neuroprotection exerted by BMSCs on ICH is due to the differentiation of BMSCs, or the trophic factors secreted into their conditioned medium (CM). In addition, growth‑associated protein‑43 (GAP‑43) is a protein associated with neurite extension, which may be considered a prospective therapeutic target in the treatment of ICH...

OBJECTIVE: Spontaneous cerebellar hemorrhages (SCH) can lead to life-threatening complications with high mortality rates of 20-50%. Although complications of SCH can be prevented by surgical therapy, there is a lack of consensus concerning the optimal surgical technique for evacuating SCH. METHODS: In this retrospective study 85 patients with SCH were divided into four treatment groups: (1) Decompression and Hematoma Evacuation via suboccipital craniectomy and removal of the posterior arch of C1 (DHE)...

BACKGROUND: In brain-injured patients intracranial pressure (ICP) is monitored invasively by a ventricular or intraparenchymal transducer. The procedure requires specific expertise and exposes the patient to complications such as malposition, hemorrhage or infection. As inner-ear fluid compartments are connected to the cerebrospinal fluid space, ICP changes elicit subtle changes in the physiology of the inner ear. Notably, we previously demonstrated that the phase of cochlear microphonic potential (CM) generated by sound stimuli rotates with ICP...

REVIEW
J D Vanderwerf, M A Kumar
Coagulopathy is common in intensive care units (ICUs). Many physiologic derangements lead to dysfunctional hemostasis; these may be either congenital or acquired. The most devastating outcome of coagulopathy in the critically ill is major bleeding, defined by transfusion requirement, hemodynamic instability, or intracranial hemorrhage. ICU coagulopathy often poses complex management dilemmas, as bleeding risk must be tempered with thrombotic potential. Coagulopathy associated with intracranial hemorrhage bears directly on prognosis and outcome...

OBJECTIVE Early radiographic findings in patients with traumatic brain injury (TBI) have been studied in hopes of better predicting injury severity and outcome. However, prior attempts have generally not considered the various types of intracranial hemorrhage in isolation and have typically not excluded patients with potentially confounding extracranial injuries. Therefore, the authors examined the associations of various radiographic findings with short-term outcome to assess the potential utility of these findings in future prognostic models...
