INTRODUCTION: Sympathetic activity from the superior cervical ganglion (SCG) has been shown to cause cerebral hypoperfusion in swine, similar to that seen with clinical cerebral vasospasm. Although the mechanism of such perfusion deficit has been speculated to be from pathologic cerebral vasoconstriction, the extent of sympathetic contribution to vasoconstriction has not been wellestablished. OBJECTIVE: We aimed to demonstrate that SCG stimulation in swine leads to significant cerebral vasoconstriction on digital subtraction angiography (DSA)...

BACKGROUND: Upright posture intolerance can be seen in a variety of diseases but the current methodology is not quantifiable and limits the ability to identify response to treatment. METHODS: A standard questionnaire was developed to assess the following aspects of upright posture tolerance: (1) How long can you stand straight without any support? (2) Do you feel any sense of sickness when you sit or lie down after standing? (3) How long do you have to wait before you are comfortable standing again after you have stood straight? (4) How effectively and fast can you get up from sitting or lying position to stand straight? and (5) rate the ability to perform activities on a standard vertical visual analog scale between 100 (can do everything) and 0 (cannot do anything)...

We describe a variant where the A2 segment of one anterior cerebral artery anastomose distal to the origin of the anterior communicating artery with the A2 segment of the contralateral anterior cerebral artery. The anastomoses are seen without any hypoplasia or aplasia of A2 segments prior to anastomoses unlike azygous or bihemispheric anterior cerebral artery. The anastomoses occur prior to bifurcation of the anterior cerebral artery into pericallosal and callosomarginal arteries.

OBJECTIVE: Flow diversion using devices such as the "pipeline" stent is now a common treatment for unruptured intracranial aneurysms. Though much is known about the efficacy of the device, less is reported regarding potential side effects. In this study, we report the frequency and characteristics of the "post-pipeline headache." METHODS: We prospectively enrolled a cohort of 222 patients who underwent pipeline stenting for the treatment of intracranial aneurysm between 2015 and 2018...

BACKGROUND: Symptomatic vasospasm (sVSP) is a common complication during the course of aneurysmal subarachnoid hemorrhage (aSAH). We aimed to evaluate the efficacy and accuracy of transcranial Doppler ultrasound (TCD), performed within the first 3 days of aSAH to predict the development of sVSP. METHODS: We performed a retrospective analysis of our institutional prospectively collected database of patients with aSAH. Patients with aSAH and World Federation of Neurosurgical Societies (WFNS) grades I-III were included in the analysis...

OBJECTIVE: The second-generation pipeline embolization device (PED), flex, has improved opening and resheathing ability compared to the first-generation classic PED device. A previously reported single-institutional study suggests that the PED flex devices are associated with lower rates of complications. However, there was limited discussion regarding the complication rate with respect to microcatheter choice for PED delivery and deployment. The present study aims to evaluate outcomes of aneurysm treatment with PED flex versus classic along with the Phenom microcatheter versus Marksman microcatheter...

BACKGROUND: Idiopathic intracranial hypertension (IIH) is a syndrome of elevated intracranial pressure of unknown etiology. Unilateral or bilateral transverse sinus (TS) or transverse-sigmoid junction stenosis is present in about 30%-93% of these patients. There is an ongoing debate on whether venous sinus stenosis is the cause of IIH or a result of it. The subset of IIH patients who continue to have clinical deterioration despite maximum medical therapy is termed as "refractory IIH." Traditionally, cerebrospinal fluid diversion surgeries (ventriculoperitoneal shunt and lumboperitoneal shunt) and optic nerve sheath fenestration (ONSF) were the mainstays of treatment for refractory IIH...

BACKGROUND/OBJECTIVE: Various strategies have been implemented to reduce acute stroke treatment times. Recent studies have shown a significant benefit of acute endovascular therapy. The JFK Comprehensive Stroke Center instituted Code Neurointervention (NI) on May 1, 2014 for the purpose of rapidly assembling the NI team and rapidly providing acute endovascular therapy. DESIGN/METHODS: We performed a retrospective analysis of all patients who had Code NI (Code NI group) called from May 1, 2014 to July 30, 2018 and compared them to patients who underwent acute endovascular treatment prior to initiation of the code (pre-Code NI group) between January 2012 and April 30, 2014...

BACKGROUND: Successful mechanical embolectomy for acute embolic arterial occlusion in the posterior cerebral circulation can potentially result in less neurologic disability and mortality. The transradial approach can potentially offer more direct navigation into the posterior circulation than the transfemoral approach and can result in faster recanalization time. OBJECTIVE: To compare procedural metrics and the technical and clinical outcomes of transradial versus transfemoral access for mechanical embolectomy in the posterior cerebral circulation...

Background: Determining cerebral infarction volume is an important part of preclinical studies to determine the benefit of potential therapies on stroke outcome. A well-known problem in determining the actual infarction volume of rodent models is the presence of edema. Because of this, algorithms must be utilized to obtain the edema-adjusted ( E A )-infarct volume. Different methods based on 2,3,5-triphenyltetrazolium hydrochloride (TTC) staining have been published describing algorithms to determine the E A -infarct volume...

Spinal dural arteriovenous fistula (SDAVF) is the most common type of spinal vascular malformation. The main purpose of endovascular treatment is to occlude the fistula site and the proximal part of the draining vein. However, this is not always possible because of the difficulty of selective catheterization in patients with tortuous feeding arteries, as well as the risk of reflux of the liquid embolic agent. Herein, we present three cases in which a dual-lumen balloon catheter together with a liquid embolic agent was used to occlude the SDAVF...

INTRODUCTION: The limited research on the management of aneurysmal subarachnoid hemorrhages (aSAHs) has not assessed the efficacy of neurology-led care. Our objective was to describe aSAH patients' outcomes after transitioning from a neurosurgery-led intensive care unit (ICU) to a neurology-led multidisciplinary care neurocritical care unit (NCCU). The study hypothesis was that the neurology-led multidisciplinary care would improve patient outcomes. METHODS: This was a retrospective cohort study...

The anterior cerebral artery (ACA) contains anatomical variants that are closely related to its embryology and development. In this study, the authors reviewed the most commonly encountered variants of the ACA and anterior communicating artery. They also reviewed the embryological origins of these variants as well as a variety of associated pathologies. Several variants are described and highlighted with illustrations including: (1) the aberrant origin of the ACA from the internal carotid artery and its developmental association with the ophthalmic artery; (2) the persistent olfactory artery; (3) the azygous ACA; (4) the triplicated ACA; and (5) multiple anterior communicating arteries...

Delayed cerebral ischemia (DCI) due to cerebral vasospasm following aneurysmal subarachnoid hemorrhage (aSAH) has long been recognized as a major source of morbidity and mortality. Early detection of cerebral vasospasm and identification of patients who are likely to become symptomatic is crucial to guide aggressive medical and/or endovascular interventions. Magnetic resonance imaging using arterial spin-label (ASL) is a noninvasive mean for assessing cerebral blood flow and is based on direct magnetic labeling of arterial blood water protons...

BACKGROUND: The Stroke Network of Wisconsin (SNOW) scale, previously called the Pomona scale, was developed to predict large-vessel occlusions (LVOs) in patients with acute ischemic stroke (AIS). The original study showed a high accuracy of this scale. We sought to externally validate the SNOW scale in an independent cohort. METHODS: We retrospectively reviewed and calculated the SNOW scale, the Vision Aphasia and Neglect Scale (VAN), the Cincinnati Prehospital Stroke Severity (CPSS), the Los Angeles Motor Scale (LAMS), and the Prehospital Acute Stroke Severity Scale (PASS) for all patients who were presented within 24 hours after onset at AHCS (14 hospitals) between January 2015 and December 2016...
