Arteriovenous malformation presenting as traumatic subdural hematoma: A case report.

Background: Brain arteriovenous malformations (AVMs) are congenital aberrant connections between afferent arteries and draining veins with no intervening capillary bed or neural parenchyma. Other than seizures, the most common initial presentation of AVM is hemorrhage, which is typically intraparenchymal, subarachnoid, or intraventricular, and very rarely subdural.

Case Description: This patient is a 66-year-old male with a history of atrial fibrillation, chronically anticoagulated with apixaban, who presented through emergency services after a fall.

Endovascular Management of Intracranial Vertebral Artery Dissection: Technical Nuances for the Preservation of Posterior Inferior Cerebellar Artery and Basilar Artery.

Background: The treatment of intracranial vertebral artery dissection (VAD) can be challenging.

Objective: To evaluate the clinical presentation, endovascular treatment techniques, and prognostic outcome of patients diagnosed with intracranial VAD at our institution.

Methods: A retrospective analysis of 35 patients who were diagnosed with VAD at our institution over 17-yr period (2001-2017) is presented.

Ethical and medicolegal aspects in the management of neurosurgical emergencies among Jehovah's Witnesses: Clinical implications and review.

When an incapacitated Jehovah's Witness neurologically deteriorates and requires immediate craniectomy, institutional protocols may delay surgery if the patient's refusal of blood products is ambiguous. We are among the first to describe such an ethically contentious case in emergency neurosurgery, review the morbidity of operative delays, discuss medicolegal concerns raised, and provide a detailed guide to hemostasis in patients who refuse blood products. We discuss the case of a 46-year-old woman presented with nausea, vomiting, and right-sided weakness, progressing to stupor over several hours.

Neurosurgical and Scalp Reconstructive Challenges During Craniotomy in the Setting of Cutis Verticis Gyrata.

Background: Cutis verticis gyrata (CVG) is a rare condition of the scalp in which thickening of the dermis induces rigid folds and furrows resembling the cerebral cortex. Two forms of primary CVG exist: essential, in which CVG is the only presenting problem, and nonessential, in which the scalp condition occurs along with neuropsychiatric ailments. CVG can also occur secondary to a variety of causes including inflammatory, neoplastic, and metabolic conditions or drug use.
