PURPOSE: Non-traumatic acute subdural hematomas (SDH) are rare and have seldom been reported in ruptured brain arteriovenous malformations (BAVM). The aim of this study was to report the frequency of acute SDH in BAVM-related hemorrhage and to determine the relationship of SDHs with BAVM angioarchitectural features. METHODS: This was a retrospective monocentric study of patients admitted for BAVM rupture between 2003 and 2017. Patients with rupture complicating or closely following partial embolization procedures were excluded...

BACKGROUND AND PURPOSE: The best embolic protection strategy has not yet been established for carotid artery stenting (CAS). This article reports a new simplified approach using a balloon guide catheter inspired by stroke therapy, in patients harboring a symptomatic ICA atherosclerotic stenosis or web. In addition, the three angiographic patterns and clinical outcomes associated with this technique, called the simple flow blockage (SFB) technique are described. MATERIAL AND METHODS: This was a retrospective study with data extraction from a monocentric prospective clinical registry of consecutive patients admitted for symptomatic ICA stenosis or web...

BACKGROUND AND PURPOSE: Several studies have shown that thrombectomy is safe and effective in occlusions of the M2 segment of the middle cerebral artery. This retrospective study compared superior and inferior division occlusions regarding radiological and clinical outcomes. METHODS: Between 2009 and 2017, patients treated with thrombectomy due to occlusion of the superior or inferior division were selected. Univariate and multivariate analyses were performed to identify predictors of outcome and compare superior and inferior division occlusions...

BACKGROUND AND PURPOSE: Endovascular treatment represents a well-established therapeutic option in patients with vertebral artery origin (VAO) stenosis. Our aim was to determine which factors affect short- and long-term restenosis rates after endovascular VAO therapy. METHODS: We conducted a single center analysis of 52 patients (36 men; age 64 ± 9.54 years) who underwent 55 endovascular procedures (27 balloon-assisted angioplasty [BAA], 28 stent-assisted angioplasty [SAA]) between 2005-2015...

PURPOSE: The Woven EndoBridge (WEB) device has been proven to be a safe and efficient endovascular treatment option for wide-necked bifurcation aneurysms. The study aimed to evaluate the incidence and risk factors of procedural complications related to WEB embolization of ruptured and unruptured intracranial aneurysms. METHODS: This was a multicenter, observational study of consecutive patients with ruptured and unruptured aneurysms who were treated with the WEB at three German tertiary care centers between May 2011 and February 2018...

PURPOSE: Leptomeningeal collaterals play a pivotal role in acute ischemic stroke. While most collateral scores rely on subjective visual analysis, an objective quantification is possible using dynamic computed tomography (CT) angiography (dynCTA). The aim was to determine the value of collateral filling delay (CFD) as assessed by dynCTA for predicting subacute stroke complications. METHODS: All subjects with isolated prebifurcation middle cerebral artery M1 occlusions were selected from an initial cohort of 2635 patients who underwent multiparametric CT for suspected stroke...

BACKGROUND AND PURPOSE: Ruptured blister-like aneurysms (BLAs) are challenging lesions to treat, without any consensus on their management. Few studies have evaluated the safety and effectiveness of flow diverter stents (FDS) for this indication, with promising results. The goal was to evaluate the safety and effectiveness of a delayed (≥5 days) flow diversion strategy for the treatment of ruptured intracranial BLAs. MATERIAL AND METHODS: A monocentric retrospective analysis of a prospectively collected database of intracranial aneurysms was performed...

PURPOSE: The aim of this study was to compare a recently established whole brain MR spectroscopic imaging (wbMRSI) technique using spin-echo planar spectroscopic imaging (EPSI) acquisition and the Metabolic Imaging and Data Analysis System (MIDAS) software package with single voxel spectroscopy (SVS) technique and LCModel analysis for determination of relative metabolite concentrations in aging human brain. METHODS: A total of 59 healthy subjects aged 20-70 years (n ≥ 5 per age decade for each gender) underwent a wbEPSI scan and 3 SVS scans of a 4 ml voxel volume located in the right basal ganglia, occipital grey matter and parietal white matter...

BACKGROUND: Retinal vasculopathy with cerebral leukoencephalopathy and systemic manifestations (RVCL-S) is a rare hereditary disease presenting with distinct imaging features in middle-aged adults. This article describes the typical imaging features focusing on the longitudinal course of RVCL-S lesions. METHODS: In this study six subjects (five male, five related) with RVCL-S were retrospectively included from two university hospitals. The median age of symptom onset was 40 ± 6 years...

PURPOSE: The brain imaging findings in children with neurological complications associated with influenza A infections are presented and analyzed and pathological imaging changes including atypical intracerebral hemorrhages in these patients are discussed. METHODS: Neuroimaging findings in six children with influenza encephalopathy following influenza A infection between 2012-2017 were retrospectively investigated. Of these five underwent magnetic resonance imaging (MRI) and one computed tomography (CT)...

PURPOSE: Gadolinium leakage in ocular structures (GLOS) on fluid-attenuated inversion recovery images (FLAIR) is a novel imaging marker in acute ischemic stroke. The present study sought to investigate the frequency and pattern of blood-retina barrier impairment in acute ischemic stroke due to internal carotid artery (ICA) stenosis or occlusion as demonstrated by GLOS. METHODS: From a magnetic resonance imaging (MRI) report database patients were identified with acute ischemic stroke due to ICA stenosis/occlusion who underwent repeated MRI with intravenous contrast agent administration and FLAIR and MR angiography (MRA)...

INTRODUCTION: Magnetic resonance imaging (MRI) has an important impact in diagnosing primary angiitis of the central nervous system (PACNS). However, neuroradiologic findings may vary immensely, making an easy and definite diagnosis challenging. METHODS: In this retrospective, single center study, we analyzed neuroradiologic findings of patients with PACNS diagnosed at our hospital between 2009 and 2014. Furthermore, we classified patients according to the affected vessel size and compared imaging characteristics between the subgroups...
