REVIEW
Joon W Shim, Joseph R Madsen
Vascular endothelial growth factor (VEGF) is a potent growth factor playing diverse roles in vasculogenesis and angiogenesis. In the brain, VEGF mediates angiogenesis, neural migration and neuroprotection. As a permeability factor, excessive VEGF disrupts intracellular barriers, increases leakage of the choroid plexus endothelia, evokes edema, and activates the inflammatory pathway. Recently, we discovered that a heparin binding epidermal growth factor like growth factor (HB-EGF)-a class of EGF receptor (EGFR) family ligands-contributes to the development of hydrocephalus with subarachnoid hemorrhage through activation of VEGF signaling...

The present study aimed to investigate whether the neuroprotective effects of p53/microRNA‑22 regulate inflammation and apoptosis in subarachnoid hemorrhage (SAH). In a mouse model of SAH, microRNA‑22 expression was upregulated. In addition, downregulation of microRNA‑22 in HEB cells increased the mRNA expression levels of interleukin (IL)‑6, induced cysteine rich angiogenic inducer 61 (Cyr61) expression, and suppressed the protein expression levels of B‑cell lymphoma 2‑associated X protein (Bax) and caspase‑3 activity...

The Japanese population features the highest rate of elderly individuals worldwide. However, the difference of actual age indication for surgical clipping (SC) and endovascular coiling (EC) has never reported. We clarified the effect of actual age on poor outcome at discharge in patients by each treatment for ruptured cerebral aneurysm according to the Japanese Stroke Data Bank. A total of 3593 patients with ruptured saccular cerebral aneurysm were treated by SC and/or EC between 2000 and 2013. The effect of actual age on poor outcome (modified Rankin scale [mRS] score > 2) at discharge was evaluated by the cutoff age using receiver operating characteristic analysis for each treatment...

INTRODUCTION: Posterior circulation aneurysms account for approximately 30% of all intracranial aneurysms, and their rupture often causes aneurysmal subarachnoid hemorrhage (aSAH). Because surgical treatment of posterior circulation aneurysms is difficult, endovascular treatment is commonly indicated. However, simple coil embolization is associated with a high rate of recanalization. Our goal was to investigate morphometric aneurysmal features assessed on pre-embolization computed tomography angiography (CTA) as predictors of recanalization in patients with posterior circulation aneurysms...

BACKGROUND AND PURPOSE: Data are scarce on both stroke incidence rates and outcomes in Greece and in rural areas in particular. We performed a prospective population-based study evaluating the incidence of first-ever stroke in the Evros prefecture, a region of a total 147 947 residents located in North Eastern Greece. METHODS: Adult patients with first-ever stroke were registered during a 24-month period (2010-2012) and followed up for 12 months. To compare our stroke incidence with that observed in other studies, we standardized our incidence rate data according to the European Standard Population, World Health Organization, and Segi population...

Background and Purpose Bax inhibitor-1 (BI-1) has been identified as a suppressor of Bax-mediated cell apoptosis by regulation of endoplasmic reticulum stress-induced cell death. However, the role of BI-1 in Early Brain Injury (EBI) after subarachnoid hemorrhage (SAH) remains unclear. In the present study, we aim to explore the neuroprotective functions of BI-1 in EBI after SAH by using models of SAH that induced endovascular perforation in rats. Method The neurological score, brain water content and blood-brain barrier (BBB) permeability were evaluated simultaneously as prognostic indicators...

Takotsubo syndrome is rare in pediatric patients but must be considered in patients with subarachnoid hemorrhage with pulmonary edema and cardiomyopathy. A systematic, collaborative approach is needed to facilitate emergent transfer of patients where extracorporeal cardiopulmonary resuscitation (e-CPR) is used as a lifesaving measure. Extracorporeal membrane oxygenation (ECMO) use in transport requires preplanning, role delineation, resources, and research efforts to be successful. We present an unusual transport case of successful e-CPR/ECMO treatment of Takotsubo syndrome in a 12-year-old boy with an isolated traumatic intracranial injury, cardiomyopathy with pulmonary edema, and multiple cardiac arrests...

PURPOSE: The role of dairy fat for the risk of stroke is not yet clear. Adipose tissue reflects long-term fatty acid intake and metabolism. We, therefore, investigated associations for percentages of adipose tissue fatty acids, for which dairy products are a major source (12:0, 14:0, 14:1 cis-9, 15:0, 17:0, 18:1 trans-11 and 18:2 cis-9, trans-11), with incident total stroke and stroke subtypes. METHODS: We conducted a case-cohort study within the Danish Diet, Cancer and Health cohort, including all incident stroke cases (n = 2108) and a random sample of the total cohort (n = 3186)...

OBJECTIVE: Blood blister-like aneurysms (BBAs) in the dorsal segment of the internal carotid artery (ICA) are fragile and difficult to treat, and the optimal treatment for BBAs is still controversial. We report clinical and angiographic results with procedural details for the treatment of BBA by using the endovascular patch embolization method. METHODS: We retrospectively reviewed patients who presented with subarachnoid hemorrhage(SAH) caused by ICA-BBAs and were treated with the endovascular patch embolization method in our center from October 2011 to March 2015...

Intracranial hemorrhage is a rare complication of spinal surgery. Case 1 was a 58-year-old man who underwent cervical laminoplasty. No apparent iatrogenic dural rupture or cerebrospinal fluid leakage was observed. An hour after the surgery, the patient had convulsions and became restless thereafter. CT revealed an intracranial SAH. The patient recovered normal consciousness the next morning. Case 2 was a 68-year-old woman who underwent cervical laminoplasty without postoperative CSF leakage. Six days after the surgery, the patient continued to complain of nausea and headache...

Xenon (Xe), a noble gas, has promising neuroprotective properties with no proven adverse side-effects. We evaluated neuroprotective effects of Xe delivered by Xe-containing echogenic liposomes (Xe-ELIP) via ultrasound-controlled cerebral drug release on early brain injury following subarachnoid hemorrhage (SAH). The Xe-ELIP structure was evaluated by ultrasound imaging, electron microscopy and gas chromatography-mass spectroscopy. Animals were randomly divided into five groups: Sham, SAH, SAH treated with Xe-ELIP, empty ELIP, or Xe-saturated saline...
