Red and White Thrombus Characteristics in Patients Undergoing Carotid Endarterectomy
Ischemic heart disease and stroke, which are associated with atherosclerosis in the coronary and carotid arteries, accounted for one-third of deaths worldwide.1 The stroke type can be ischemic or hemorrhagic. Hemorrhagic stroke is divided into intracerebral and subarachnoid hemorrhage types. Ischemic stroke occurs because of small vessel occlusion, large artery atherosclerosis, cardiogenic embolism, and other causes.2 Ischemic stroke and transient ischemic attack (TIA) usually arise from unstable carotid lesions, which cause thrombus formation or carotid artery occlusion.

Intracerebral Hemorrhage Associated with Oral Phenylephrine Use: A Case Report and Review of the Literature
Conclusions: It is scientifically plausible that phenylephrine may cause strokes, consistent with the pharmacologic properties and adverse event profiles of similar amphetamine-like sympathomimetics. As RCVS has been well described in association with over-the-counter sympathomimetics, a likely, although not definitive, causal relationship between phenylephrine and ICH is proposed.

Racial and Ethnic Disparities in Mortality in US Veterans Following an Incident Subarachnoid Hemorrhage
Blacks and Hispanics have been shown to have higher stroke mortality than Whites. However, few studies have investigated health disparities in post-stroke mortality for specific stroke types, such as subarachnoid hemorrhage (SAH). We analyzed risk of mortality by race/ethnicity after incident SAH in a national sample of stroke patients from the Veteran's Health Administration (VHA).

Profile of Patients with Cerebral Venous Sinus Thrombosis with Cerebellar Involvement
Conclusions: Cerebellar involvement in CVT is very rare, and high index of suspicion is required for diagnosis. Imaging with CT and MRI will help in confirming the diagnosis. Conventional anticoagulation is effective in treatment. Mortality was 33%, and there was no disability in survivors.

Anterior Cerebral Artery Dissection in a Patient With Autosomal Dominant Polycystic Kidney Disease
Intracranial artery dissection secondary to autosomal dominant polycystic kidney disease is far less common than cerebral aneurysm. A 55-year-old man presented a sudden onset of headache and disturbed consciousness caused by ischemic stroke in the bilateral frontal lobes with minor subarachnoid hemorrhage. The bilateral anterior cerebral arteries were firstly occluded and re-perfused with irregular narrowing and dilation in 3 days after stroke onset, indicating dissection. He was diagnosed with autosomal dominant polycystic kidney disease by abdominal CT findings and by his family history though his renal function was almost normal.

Changes in the cerebrospinal fluid lipid profile following subarachnoid hemorrhage in a closed cranium model: Correlations to cerebral vasospasm, neuronal cell death and Interleukin-6 synthesis. A pilot study
Phospholipids and sphingolipids are cell membrane components, that participate in signaling events and regulate a wide variety of vital cellular processes. Sphingolipids are involved in ischemic stroke pathophysiology. Throughout cleavage of membrane sphingomyelin by sphingomyelinase in stroke patients, it results in increased Ceramide (Cer) levels in brain tissue. Different studies showed the evidence that sphingomyelinase with Cer production induces expression of interleukin (IL)-6 and have vasoconstrictive proprieties.

Nomogram for predicting delayed cerebral ischemia after aneurysmal subarachnoid hemorrhage in the Chinese population
The incidence of stroke is high worldwide1 and is the leading cause of death in China presently.2,3 Subarachnoid hemorrhage caused by ruptured intracranial aneurysm is a subtype of severe stroke that occurs suddenly in seemingly healthy individuals with generally poor prognosis.4 Surgical clipping and endovascular coiling are effective treatment modalities for patients with aneurysmal subarachnoid hemorrhage (aSAH). Delayed cerebral ischemia (DCI) is a complication of aSAH, occurring in up to 30% of patients,5 and is an important cause of disability and death, often leading to deterioration of patients ’ condition or quality of life.

Convexity Subarachnoid Hemorrhage Soon after Starting a Direct Oral Anticoagulant in 2 Patients with Acute Infarction
Convexity subarachnoid hemorrhage (cSAH) is typically due to head trauma, but various nontraumatic causes for cSAH are known also. Nontraumatic cSAH is most commonly associated with cerebral amyloid angiopathy (CAA) in the elderly or with reversible cerebral vasoconstriction syndrome in younger subjects,1 but cSAH rarely occurs subsequent to acute ischemic stroke.2 Direct oral anticoagulants (DOACs) are used to reduce the risk of ischemic stroke and systemic embolism in patients with non-valvular atrial fibrillation and have favorable bleeding profiles as compared with warfarin,3,4 but here we describe 2 cSAH patients who ...

Preadmission Beta-blockers Are Associated with Decreased Incidence of Neurogenic Stunned Myocardium in Aneurysmal Subarachnoid Hemorrhage
Background: Neurogenic stunned myocardium (NSM) is a frequent complication of aneurysmal subarachnoid hemorrhage (aSAH), with a significant impact on disease course. The presumed cause is catecholamine surge at the time of aneurysm rupture. Beta-blockers, which reduce the impact of the catecholamine surge, may decrease the risk of developing NSM.Methods: A chart review of 234 consecutive patients admitted to the Oregon Health and Science University Neurosurgery service between March 6, 2008 and June 23, 2010 with a diagnosis of aneurysmal SAH was performed. This group was further subdivided by patients who received echocar...

Nontraumatic Convexity Subarachnoid Hemorrhage: Different Etiologies and Outcomes
Conclusions: Significant ICA atherosclerotic stenosis was the most frequent cause of cSAH in our series, reinforcing that cSAH should prompt vascular imagiological evaluation including cervical vessels. Outcomes in cSAH seem to be related to etiology. Patients with undetermined etiology should be followed up because cSAH may be the first manifestation of CAA.

Current Utility of Diagnostic Catheter Cerebral Angiography
Conclusions: Our snapshot of 200 consecutive catheter cerebral angiograms shows that it is used for both primary diagnosis and surveillance in a wide variety of indications. Despite recent imaging trends, diagnostic catheter angiography provides clinically meaningful diagnostic information in enough cases to warrant continued use.

Is Early Clinical Evidence of Autonomic Shift Predictive of Infection after Aneurysmal Subarachnoid Hemorrhage
Background: Autonomic shift (AS), characterized by increased sympathetic nervous system activation, has been implicated in neurologically mediated cardiopulmonary dysfunction and immunodepression after stroke. We investigated the prevalence of AS defined by readily available clinical parameters and determined the association of AS with subsequent infection in a cohort of patients with aneurysmal subarachnoid hemorrhage (aSAH).Methods: Data were obtained from a single-center cohort study of aSAH patients admitted from January 1, 2007, through April 1, 2012. AS was defined as at least 1 early (
