OBJECTIVE: To observe the short-term efficacy of Pipeline embolization divice (PED) for the treatment of complex intracranial aneurysms. METHODS: The clinical data of 29 consecutive patients with 32 intracranial aneurysms treated with PED between April 2015 to September 2016 were analyzed retrospectively. There were 3 small aneurysm, 15 large aneurysms, 8 giant aneurysms, 5 fusiform ayneurysms and 1 recidivation. The vessels include 25 anterior circulation and 4 posterior circulation...

Background: Cerebral aneurysms are a kind of cardiovascular diseases which are accompanied with high morbidity and mortality due to rupturing and causing subarachnoid hemorrhages. The current study aimed to determine epidemiologic and demographic features and prognosis of patients with cerebral aneurysms. Materials and Methods: In this cross-sectional study, 465 patients with cerebral aneurysms hospitalized in Al-Zahra Hospital were studied. The required information including demographic, epidemiologic, and clinical features of the disease were extracted from their records...

Cerebral vasospasm (CVS) is a severe complication that occurs following aneurysmal subarachnoid hemorrhage (SAH). Magnetic resonance angiography (MRA) has been used to evaluate brain injury following SAH in humans. The present study was designed to assess a rabbit model of symptomatic CVS (SCVS) and the utility of MRA in evaluating SCVS in rabbits. Japanese white rabbits (n=24) were randomly divided into 2 equal groups: A sham group and a SAH group. Neurological scores were evaluated for 7 days following SAH...

BACKGROUND: In patients with non-aneurysmal subarachnoid hemorrhage (NA-SAH), the etiology is unknown and the bleeding source remains unidentified. However, the ABO blood type system has a profound role in patient's hemostasis and thrombosis. To date, the aspect of ABO blood type in incidence, clinical course, and outcome after NA-SAH has not been investigated. METHODS: In this retrospective analysis, 81 patients with non-traumatic and non-aneurysmal subarachnoid hemorrhage treated between 2010 and 2014 at the author's institution were included...

BACKGROUND: Oncotic aneurysm is a rare condition with a high mortality rate. Since no consensus has been reached regarding therapeutic strategy for ruptured oncotic aneurysm, treatment remains challenging. CASE DESCRIPTION: A 35-year-old woman developed sudden onset of severe headache. Computed tomography showed subarachnoid hemorrhage and cerebral angiography revealed two fusiform aneurysms in the distal portion of the left middle cerebral artery. Aneurysmectomy with vessel reconstruction using a superficial temporal artery graft was performed to maintain blood flow to the distal middle cerebral artery...

OBJECTIVES: Crimean-Congo Hemorrhagic Fever (CCHF) is a fatal, tick-borne disease. The classic clinical presentation of CCHF is characterized by sudden onset of high fever, chills, and severe headache. There are no previous reports on the characteristics of headaches caused by CCHF. Therefore, we investigated the relationship between CCHF-induced headache and the clinical course of the disease. METHODS: We included 60 patients with headache diagnosed with CCHF; they were divided into two groups: group 1 included patients with hospital stay <7 days and group 2 included patients with hospital stay >7 days...

INTRODUCTION/PURPOSE: Mechanical thrombectomy (MT) for acute ischemic stroke (IS) can be performed also in patients on anticoagulation therapy (AT); however, sufficient and reliable data about safety and efficacy of MT are still missing. Thus, we aimed to compare these parameters between patients treated on AT and without AT. MATERIALS AND METHODS: All consecutive IS patients treated with MT using stent retrievers were included in the retrospective analysis. Neurological deficit was scored using National Institutes of Health Stroke Scale (NIHSS) and 90-day clinical outcome using modified Rankin scale with a score 0-2 for good outcome...

PURPOSE: Imaging findings of pilocytic astrocytoma (PA) vary widely, sometimes resembling those of high-grade glioma (HGG). This study aimed to identify the imaging parameters that can be used to differentiate PA from HGG. METHODS: Altogether, 60 patients with PAs and 138 patients with HGGs were included in the study. Tumor properties and the presence of hydrocephalus, peritumoral edema, and dissemination were evaluated. We also measured the maximum relative cerebral blood flow (rCBF max ) and volume (rCBV max ) and determined the minimum apparent diffusion coefficient (ADC min ) in the tumor's solid components...

CASE: A 71-year-old woman was receiving dialysis for microscopic polyangiitis(MPA). She was transported to the emergency room after developing a headache and losing consciousness. She was in a coma and had dense left paralysis. Head computed tomography(CT)showed a subarachnoid hemorrhage. Head three-dimensional CT angiography showed an aneurysm proximal to the right M2(inferior trunk), which was considered as the source of bleeding. We performed an emergency aneurysm clipping surgery...

Fasudil is a clinically approved Rho-associated protein kinase (ROCK) inhibitor that has been used widely to treat cerebral consequences of subarachnoid hemorrhage. It is known to have a positive effect on animal models of neurological disorders including Parkinson's disease and stroke. However, its cellular effect on progenitor populations and differentiation is not clearly understood. While recent studies suggest that fasudil promotes the mobilization of neural stem cells (NSCs) from the subventricular zone in vivo and promotes the differentiation of the C17...

Background: Several mechanical thrombectomy (MT) devices have been designed with the goal of improving the recanalization rates of major intracranial artery occlusions. Objective: In this single-center experience, we analyzed the acute ischemic stroke (AIS) treatment with Primary MT; safety and efficacy and clinical results in our patients with large vessel occlusion (LVO). Methods: During a five-year period (from September 2011 to July 2016), out of 996 patients who presented to our center with a diagnosis of AIS, 113 (11...

Cerebral Amyloid Angiopathy (CAA) is one of the significant causes of lobar intracerebral hemorrhage (ICH) mainly among elderly people. Sporadic cases of CAA have been linked to genetic polymorphisms with an increased risk of disease, an earlier presentation, and an accelerated pathology [1]. Here, we present a patient with no significant risk factors who had a recurrent intracerebral hemorrhage secondary to CAA probably induced by exercise.

Despite successful management of ruptured intracranial aneurysm following subarachnoid hemorrhage (SAH), delayed cerebral ischemia (DCI) remains the main cause of high mortality and morbidity in patients who survive the initial bleeding. Astrocytes play a key role in neurovascular coupling. Therefore, changes in the neurovascular unit including astrocytes following SAH may contribute to the development of DCI and long-term complications. In this study, we characterized morphological changes in hippocampal astrocytes following experimental SAH, with special emphasis on glia-vascular cross-talk and hippocampal volume changes...

BACKGROUND: Premature infants are at high risk for developmental delay and cognitive dysfunction. Besides medical conditions, growth restriction is regarded as an important risk factor for cognitive and neurodevelopmental dysfunction throughout childhood and adolescence and even into adulthood. In this study, we analyzed the relationship between post-discharge body weight and psychomotor development using a nationwide dataset. MATERIALS AND METHODS: This was a nationwide cohort study conducted in Taiwan...

Internal carotid arterial system is the main source of blood supply in brain. In forensic identification practice, blunt injures of internal carotid arterial system usually cause complications such as thrombus, aneurysm and arteriovenous fistula, etc. The deaths following delayed cerebral infarction or intracranial haemorrhage are not rare. At present, literature of deaths caused by blunt injuries of internal carotid arterial system mainly consist of case reports in China. This paper reviews related literature and case reports at home and abroad, and summarizes forensic medical features and identification method of the deaths caused by such injuries...

BACKGROUND AND PURPOSE: In patients with hemorrhagic contusions, hematoma volumes are overestimated on follow-up standard 120-kV images obtained after contrast-enhanced whole-body CT. We aimed to retrospectively determine hemorrhagic progression of contusion rates on 120-kV and 190-keV images derived from dual-energy CT and the magnitude of hematoma volume overestimation. MATERIALS AND METHODS: We retrospectively analyzed admission and follow-up CT studies in 40 patients with hemorrhagic contusions...
