BACKGROUND: Surgical risk in patients with unruptured aneurysms is well known. The relative impact of surgery and natural history of subarachnoid haemorrhage (SAH) on patients in good clinical condition (World Federation of Neurological Surgeons [WFNS] grades 1 and 2) is less well quantified. The aim of this study was to determine causes of poor outcome in patients admitted in good grade SAH. METHODS: A retrospective study of prospectively collected data among WFNS-1 and -2 patients: demographics, SAH and aneurysm-related data, surgical complications and outcome as assesed by the Glasgow Outcome Scale (GOS)...

: Blister aneurysms at non-branching sites of the dorsal internal carotid artery (dICA) are fragile, rare, and often difficult to treat. The purpose of this study is to address the demographics, treatment modalities, and long-term outcome of patients treated for dICA blister aneurysms. A retrospective review of medical records identified all consecutive patients who presented with a blister aneurysm from 2002 to 2011 at our institution. Eighteen patients (M=7, F=11; mean age: 48.4±15...

OBJECTIVE: The pathophysiological mechanisms underlying cerebral vasospasm following aneurysmal subarachnoid hemorrhage (aSAH) remain poorly understand. Ryanodine receptors (RYR) are intracellular calcium channels involved in the regulation of vascular smooth muscle cells and cerebrovascular tone and diameter. Previous work reported an association between a RYR polymorphism and cerebral vasospasm. Here, we sought to assess the impact of that RYR polymorphism on aSAH and its clinical sequelae...

BACKGROUND: Shunt-dependent hydrocephalus (SDH) is a well-known sequela following aneurysmal hemorrhage, adversely affecting the outcome after securing ruptured aneurysm. Fenestration of lamina terminalis (FLT) creates an anterior ventriculostomy, facilitates cerebrospinal fluid circulation and clot clearance in the basal cistern. However, controversy exists over whether microsurgical FLT during aneurysm repair can decrease the incidence of SDH. AIMS: The study is designed to determine the efficacy of lamina terminalis fenestration on the reduction of SDH after aneurysm clipping...

BACKGROUND: Delayed cerebral ischemia (DCI) contributes to morbidity following aneurysmal subarachnoid hemorrhage; however, its etiology remains poorly understood. DCI is not only a consequence of angiographic vasospasm, but also involves microthrombosis and neuroinflammation, two events with unexplained phenomenology. The vascular endothelial glycocalyx mediates platelet aggregation and endothelial cell-leukocyte interactions and may play an important role in DCI pathogenesis. METHODS: We present a case series in which we conducted multiplex and singlet enzyme-linked immunosorbent assays of endothelial, glycocalyx, inflammatory, and neuroinjury proteins in both CSF and plasma in three patients during active DCI following SAH...

High-mobility group box 1 protein (HMGB1) has been implicated in inflammatory responses, and is also associated with cerebral vasospasm after subarachnoid hemorrhage (SAH). However, there are no direct evident links between HMGB1 and cerebral vasospasm. We therefore investigated the effects of HMGB1 on pial arteriole reactivity following SAH in rats. We initially found that SAH induced a significant decrease in pial arteriole dilating responses to sciatic nerve stimulation (SNS), hypercapnia (CO2), and the topical suffusion of acetylcholine (ACh), adenosine (ADO), and s-nitroso-N-acetylpenicillamine (SNAP) over a 7-day period after SAH...

OBJECTIVE: The occurrence of cerebral vasospasm after onset of aneurysmal subarachnoid hemorrhage (SAH) is a critical factor determining the clinical prognosis. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), both omega-3 fatty acids (O-3FA), can suppress cerebral vasospasm and DHA can relax vessels vasoconstriction and have neuroprotective effects. In the present study, we investigated whether administration of O-3FA prevented cerebral vasospasm occurrence and improved clinical outcomes following aneurysmal SAH...

BACKGROUND AND PURPOSE: For patients with cerebral vasospasm refractory to medical and hemodynamic therapies, endovascular therapies often remain the last resort. Data from studies in large cohorts on the efficacy and safety of multiple immediate endovascular interventions are sparse. Our aim was to assess the feasibility and safety of multiple repeat instant endovascular interventions in patients with cerebral vasospasm refractory to medical, hemodynamic, and initial endovascular interventions...

Tuberculous meningitis (TBM) causes significant morbidity and mortality. The primary objective was to re-examine the concept of "TB zone" and "ischaemic zone" in cerebral infarction in patients with tuberculous meningitis. The secondary objective was to evaluate cerebral infarction, vasculitis and vasospasm in tuberculous meningitis infections. Between 2009 and 2014, TBM patients were recruited. Neuroimaging was performed and findings of cerebral infarction, vasculitis and vasospasm were recorded. Infarcts were classified based on arterial supply and Hsieh's classification...

Although delayed cerebral vasospasm (DCV) following subarachnoid hemorrhage (SAH) is closely related to the progression of brain damage, little is known about the molecular mechanism underlying its development. High mobility group box-1 (HMGB1) plays an important role as an initial inflammatory mediator in SAH. In this study, an SAH rat model was employed to evaluate the effects of anti-HMGB1 monoclonal antibody (mAb) on DCV after SAH. A vasoconstriction of the basilar artery (BA) associated with a reduction of nuclear HMGB1 and its translocation in vascular smooth muscle cells were observed in SAH rats, and anti-HMGB1 mAb administration significantly suppressed these effects...

BACKGROUND: Transcranial Doppler (TCD) is endorsed by national guidelines for use in aneurysmal subarachnoid hemorrhage (aSAH) for surveillance of cerebral vasospasm (CV). However, nationwide data on utilization of TCD for CV detection and monitoring in aSAH are lacking. METHODS: Analysis of nationwide trends in TCD prevalence was performed using Nationwide Inpatient Sample (NIS) data from 2002 to 2011. Raw counts were converted into weighted counts, which were used to generate national estimates...

A 17-year-old male with ADHD who was treated with sertraline and lisdexamfetamine presented with transient episodes of speech impairment and right-sided hemiparesis preceded by headaches. Magnetic resonance imaging revealed three cerebral ischaemic lesions. Treatment was initiated with aspirin and discontinued with lisdexamfetamine. In the literature a causal relationship between treatment with central stimulants and the development of cerebrovascular events has not been substantiated. Vasospasm and paroxystic tachycardia may be associated with the event, but lisdexamfetamine and sertraline cannot be ruled out as risk factors...

Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by segmental vasospasm and it is often accompanied by either posterior reversible encephalopathy syndrome or stroke. However, other MRI abnormalities have rarely been reported. A 28-year-old woman presented with a thunderclap headache immediately after delivery; MRI showed segmental vasoconstriction and an abnormal signal in the splenium of the corpus callosum. Neuroimaging abnormalities normalized 20 days after the first examination. Only two cases of RCVS with transient splenial lesions (TSL) have so far been reported...

We present a case of imaging proven cerebral vasospasm causing ischemic stroke in a young patient chronically on buprenorphine-naloxone for heroin remission who started smoking cannabis on a daily basis. With cannabis legalization spreading across the states in the USA, it is important for physicians not only to be aware of cannabis reported association with cerebral vasospasm in some patients but also to be on the lookout for possible interacting medications that can synergistically affect cerebral vessels causing debilitating strokes...

BACKGROUND AND PURPOSE: Cerebral infarction after aneurysmal subarachnoid hemorrhage is a significant cause of substantial morbidity and mortality. Because early and delayed cerebral infarction after aneurysmal subarachnoid hemorrhage may be mediated by different processes, we evaluated whether aneurysm-securing methods contributed to infarcts and whether long-term outcomes differ between early and delayed infarcts. METHODS: A post hoc analysis of the CONSCIOUS-1 study (Clazosentan to Overcome Neurological Ischemia and Infarction Occurring After Subarachnoid Hemorrhage) was performed...

BACKGROUND: Reversible cerebral vasoconstriction syndrome (RCVS), also known as Call-Fleming syndrome, is characterized by thunderclap headaches, non-aneurysmal segmental cerebral vasoconstriction seen on arteriogram, and spontaneously resolves within twelve weeks. Fingolimod has been reported to cause posterior reversible encephalopathy syndrome (PRES) and one case of RCVS. OBJECTIVE: We report a case of RCVS possibly related to fingolimod use, and compare to cases of adverse outcomes in fingolimod use...
