BACKGROUND AND PURPOSE: Multiply occurring intracranial dural arteriovenous fistulas (dAVFs) have been documented but rarely occur, and neither pathogenesis nor prognosis is clearly understood. This study was conducted to analyze angiographic characteristics of multiple dAVFs and to chronicle our treatment experience. METHODS: Between April, 2002 and January, 2018, data prospectively collected from 310 patients with intracranial dAVFs were systematically reviewed, assessing clinical and anatomic outcomes of endovascular treatment in 32 patients with multiple dAVFs (≥2 fistulas each)...

Ischemic stroke is the most common neurological complication of cardiac catheterization resulting in a high morbidity and mortality. We present a 44-year-old man admitted for vasospastic angina that suffered a right middle cerebral artery (MCA) occlusion after a cardiac catheterization. Mechanical thrombectomy was indicated and complete arterial recanalization was achieved. The material obtained showed a fragment of a healthy artery. Partial radial endarterectomy and cerebral embolization may be a rare complication of cardiac catheterization...

Background and purpose - Neurite orientation dispersion and density imaging (NODDI) is a new technique that applies a three-diffusion-compartment biophysical model. We assessed the usefulness of NODDI for the differentiation of glioblastoma from solitary brain metastasis. Methods - NODDI data were prospectively obtained on a 3 T magnetic resonance imaging (MRI) scanner from patients with previously untreated, histopathologically confirmed glioblastoma (n = 9) or solitary brain metastasis (n = 6). Using the NODDI Matlab Toolbox, we generated maps of the intracellular-, extracellular-, and isotropic volume (VIC, VEC, VISO) fraction...

PURPOSE: To explore the association between presence of inflammatory cells in the carotid plaques surgically treated and brain MRI findings. MATERIAL AND METHODS: Forty consecutive patients were prospectively analyzed. Brain MRI was performed with a 1.5 Tesla scanner and infacts (lacuna and non-lacunar) pertinence of the anterior circulation were recorded. All patients underwent carotid endarterectomy "en bloc"; carotid plaques histological sections were prepared and immuno-cytochemical analysis was performed to characterize and quantify the presence of inflammatory cells...

Introduction Although the ascending pharyngeal artery (APhA) is known as a main feeder of carotid body tumors (CBTs), its detailed architecture and embryological consideration have not been described. The objective of this study was to describe the architecture of a descending feeder of the APhA and to consider its origin embryologically through a review of our CBT embolizations. Methods We retrospectively analyzed data from patients with CBTs who underwent transarterial embolization or angiographic examination-only between July 2010 and February 2017...

BACKGROUND AND PURPOSE: In patients with Meniere's disease (MD), saccular hydrops can only be studied by magnetic resonance imaging (MRI) at a late stage when the disease is already responsible for moderate to severe hearing loss. However, these patients may also present vestibular aqueduct (VA) abnormalities. MATERIALS AND METHODS: In this prospective study (38RC14.428 for healthy subjects / 38RC15.173 for patients), imaging was carried out on a 3 T MRI scanner...

The Woven EndoBridge (WEB) device is intended to treat wide-neck bifurcation aneurysms. the morbimortality reported in the literature is low. Described postoperative thromboembolic complications of WEB are fairly limited in terms of chronology and management, as low rates of thromboembolic complications at more than one week of treatment are reported. A 60-year-old patient was treated for an unruptured wide-necked middle cerebral artery (MCA) bifurcation aneurysm with a WEB device. Despite preventive dual anti-platelets therapy, eight days after the implantation she presented an acute ischemic stroke with an in situ thrombotic complication...

BACKGROUND AND PURPOSE: Intracerebral steal is a paradoxical vasodilatory response that reduces cerebral blood flow (CBF) in hemodynamically compromised brain tissue when blood is rerouted to more healthy areas. The aim of our study was to investigate the presence and extent of steal in patients with steno-occlusive internal carotid artery (ICA) disease, and to assess its relation with collateral blood flow through the circle of Willis (CoW). MATERIALS AND METHODS: Thirty-eight patients with symptomatic steno-occlusive ICA disease underwent MRI examination with arterial spin labeling (ASL) perfusion imaging before and after a vasodilatory challenge...

BACKGROUND: Spinal dural arteriovenous fistulas (SDAVF) are usually solitary lesions. Synchronous and/ or metachronous double SDAVF have rarely been reported in the literature. We report on three patients with double SDAVF and present our single center experience in the diagnostic and treatment management in these patients. MATERIAL AND METHODS: We retrospectively revised our medical database for all patients who were diagnosed and treated in our center due to a SDAVF between 1990 and 2017...

BACKGROUND: Differentiation between glioblastoma and brain metastasis may be challenging in conventional contrast-enhanced MRI. PURPOSE: To investigate if perfusion-weighted MRI is able to differentiate glioblastoma from metastasis and, as a second aim was to see if it was possible in the latter group, to predict the primary site of neoplasm. MATERIAL AND METHODS: Hundred and fourteen patients with newly discovered tumor lesion (76 metastases and 38 glioblastomas) underwent conventional contrast-enhanced MRI including dynamic susceptibility contrast perfusion sequence...

BACKGROUND AND PURPOSE: Choice of anesthesia type on outcome for mechanical thrombectomy (MT) in acute ischemic stroke remains controversial. The goal of our research was to study the impact of anesthesia strategy on the delay, angiographic and neurological outcome of MT performed under general anesthesia (GA) vs. conscious sedation (CS). METHODS: This prospective, single-center observational study included patients with anterior circulation large vessel occlusion (ACLVO) strokes treated with MT within 6 hours of symptom onset...

BACKGROUND: Dural venous sinus stenting (DVSS) is an accepted treatment option in selected patients with medically refractory idiopathic intracranial hypertension and obstructive venous outflow physiology prior to cerebrospinal flow diversion (CSFD) surgery. There are no randomized controlled studies focusing on outcomes and complication rates for dural venous sinus stenting. PURPOSE: We present the largest comprehensive meta-analysis on DVSS for idiopathic intracranial hypertension (IIH) focusing on success rates, complications, and re-stenting rates to date...

PURPOSE: Aim of this study was to evaluate the collateral blood flow between more distal branches of the middle cerebral artery (MCA) in the case of peripheral MCA branch occlusion on dynamic 4D angiograms. We sought to individually predict the finally resulting infarction volume with regard to the extent of collateral blood flow. METHODS: Overall, 35 acute ischemic stroke patients with peripheral MCA branch occlusion were included. Volumes of the ischemic infarctions and perfusion deficits were measured on diffusion weighted images DWI and time-to-peak TTP (>4S)...
