OBJECTIVE Smoking is a known risk factor for aneurysm development and aneurysmal subarachnoid hemorrhage, as well as subsequent vasospasm in both untreated individuals and patients who have undergone surgical clipping of cerebrovascular aneurysms. However, there is a lack of data in the current scientific literature about the long-term effects that smoking has on the integrity of endovascular repairs of cerebral aneurysms. This study was designed to determine if any smoking history increased the risk of poorer outcomes and/or aneurysm recurrence in patients who have had endovascular repair of cerebral aneurysms...

We report a case in which strict anticoagulant therapy management was useful for a recurrent in-stent thrombosis after carotid artery stenting (CAS). An 84-year-old man presented with cognitive decline that progressed rapidly over two months. Head magnetic resonance imaging showed an acute-stage infarct occurring frequently in the right cerebral hemisphere, and he underwent hospitalization and treatment. On neck magnetic resonance angiography (MRA), severe stenosis was found at the origin of the right internal carotid artery...

Moyamoya disease is a unique occlusive disease of the internal carotid artery(ICA)with moyamoya vessels that can lead to transient ischemic attacks and hemorrhagic stroke. When other inherited or acquired disorders and conditions occur in conjunction with moyamoya disease, the syndrome is known as quasi-moyamoya disease. We report the case of a 34-year-old woman with a past history of SAPHO(Synovitis-Acne-Pustulosis-Hyperostosis-Osteomyelitis)syndrome, who presented with arm weakness and headache. Magnetic resonance angiography revealed severe terminal stenosis of the left ICA with moyamoya vessels, and she was diagnosed as moyamoya disease associated with SAPHO syndrome...

Dural arteriovenous fistula(dAVF)is relatively rare, and its etiology remains uncertain. Generally, dAVF is thought to be acquired and has been reported to develop secondary to sinus thrombosis, head injury, infection, and surgery. We report a rare case of dAVF in the anterior cranial fossa that developed remote from the craniotomy site after surgery. A 52-year-old man underwent surgery for hypertensive intracerebral hemorrhage 4 years prior. Perioperative imaging modalities demonstrated no abnormal vascular malformation except for an un-ruptured anterior communicating artery aneurysm...

Intracranial chondromas are rare tumors, especially in the pediatric population. We describe the conventional and advanced neuroimaging characteristics of this rare convexity dura-based chondroma in a young adolescent. In particular we demonstrate that diffusion-weighted imaging (DWI) facilitates differentiation between a dura-based chondroma and the more frequent classical meningioma. Chondromas are typically DWI hypointense with high apparent diffusion coefficient (ADC) values while meningiomas are typically DWI hyperintense with low ADC values...

Behçet's disease (BD) is systemic vasculitis of unknown etiology, which is more common in the countries located along the Great Silk Road. The disease is diagnosed if a patient has 4 key diagnostic signs: aphthous stomatitis, genital sores, and eye and skin lesions. Vascular diseases referred to as minor criteria for BD are characterized by the formation of aneurysms and thrombosis, predominantly in the venous bed. In venous disorders, a blood clot can form in any vessel, including caval, cerebral, pulmonary, and other veins...

Importance: The computed tomographic angiography (CTA) spot sign is associated with intracerebral hemorrhage (ICH) expansion and may mark those patients most likely to benefit from intensive blood pressure (BP) reduction. Objective: To investigate whether the spot sign is associated with ICH expansion across a wide range of centers and whether intensive BP reduction decreases hematoma expansion and improves outcome in patients with ICH and a spot sign. Design, Setting, and Participants: SCORE-IT (Spot Sign Score in Restricting ICH Growth) is a preplanned prospective observational study nested in the Antihypertensive Treatment of Acute Cerebral Hemorrhage II (ATACH-II) randomized clinical trial...

BACKGROUND: Young women are usually protected against coronary artery disease due to hormonal and risk-factor profile. Previous studies have suggested poorer outcome in women hospitalized with acute coronary syndrome as compared to men. However, when adjusted to age and other risk factors, this difference does not remain significant. We compared the risk-profile and outcome between young (≤55) women and men admitted with acute coronary syndrome. METHODS: We analyzed clinical characteristics, management strategies, and outcomes of men and women ≤55y enrolled in the biennial Acute Coronary Syndrome Israeli Surveys (ACSIS) between 2000 and 2013...

BACKGROUND: Most ruptured cerebral aneurysms are small (<7 mm). Evidence suggests low rupture rates for such lesions (<1% per year). Population studies demonstrate a prevalence rate of 3.2%. This study simultaneously estimates the prevalence of aneurysms in a single geographic population while reporting the observed rate of aneurysmal subarachnoid hemorrhage (aSAH) in the same geographic region composed of a poor urban minority demographic. METHODS: This is an institutional review board-approved, Health Insurance Portability and Accountability Act of 1996-compliant retrospective study performed between 2005 and 2011 at a single center...

Chronic cerebral hypoperfusion (CCH) evokes mild cognitive impairment (MCI) and contributes to the progression of vascular dementia and Alzheimer's disease (AD). How CCH induces these neurodegenerative processes that may spread along the synaptic network and whether they are detectable at the synaptic proteome level of the cerebral cortex remains to be established. In the present study, we report the synaptic protein changes in the cerebral cortex after stepwise bilateral common carotid artery occlusion (BCCAO) induced CCH in the rat...

Blood-brain barrier (BBB) breakdown, inflammatory and immune cell activation, and chronic cerebral hypoperfusion are features of multiple sclerosis (MS). The aim is to determine the influence of endothelin-1 (ET1) and asymmetric dimethylarginine (ADMA) on cerebral circulation time (CCT) in patients with MS. In all, 64 patients with MS (39 relapsing-remitting [RR]-MS; 25 secondary progressive [SP]-MS subtype) and 37 controls (C) were studied. Cerebral circulation time was obtained by angiography. Plasmatic ET1 and ADMA were measured by enzyme-linked immunosorbent assay...

BACKGROUND: Stereotactic radiosurgery (SRS) is a treatment option for cerebral arteriovenous malformations (AVMs) to prevent intracranial hemorrhage. The decision to proceed with SRS is usually based on calculated nidal volume. Physicians commonly use the ABC/2 formula, based on digital subtraction angiography (DSA), when counseling patients for SRS. OBJECTIVE: To determine whether AVM volume calculated using the ABC/2 method on DSA is accurate when compared to the exact volume calculated from thin-cut axial sections used for SRS planning...

Background The importance of both porosity and pore density of a flow diverter is well recognized in treatment of intracranial aneurysms; however, understanding of the effect of individual wire (wire number and size) is critical in improving device design and use. Methods A total of 10 multi-layered flow diverters with different wire numbers (32, 48, 56, and 72) and sizes (30, 35, and 40 µm) were implanted into identical patient-specific middle cerebral artery aneurysm models. Digital subtraction angiography was acquired at 30 f/s and X-ray signals at three selected regions of interest were compared to determine the amount of intra-aneurysmal flow...

Hemorrhagic complication is one of the notable surgical complications of the revascularization surgery for moyamoya disease (MMD). Cerebral hyperperfusion (CHP) has been considered as the underlying cause of this complication. It mostly occurs several days after surgery, but the intra-operative hemorrhage immediately after bypass has not been reported previously. A 21-year-old woman presented right thalamic hemorrhage and was diagnosed as having MMD by cerebral angiography. In light of the location of the hemorrhage at the vascular territory of posterior circulation and the manifestation of transient ischemic attack during the follow-up period, she underwent revascularization surgery to prevent future ischemic attack and rebleeding...
