Endoluminal reconstruction with flow-diverting stents represents a widely accepted technique for the treatment of complex intracranial aneurysms. This European registry study analyzed initial experience 15 neurovascular centers Flow-Redirection Intraluminal Device (FRED) system.Consecutive patients aneurysms treated FRED between February 2012 and March 2015 were retrospectively reviewed. Complications adverse events, transient permanent morbidity, mortality, occlusion rates evaluated.During...
<h3>BACKGROUND AND PURPOSE:</h3> The safety and efficiency of the dual-layer Woven EndoBridge (WEB) device has already been published. However, this international multicenter study sought to evaluate single-layer devices, which are newest generation WEB intrasaccular flow-disrupter family. They have designed offer smaller-sized devices with a lower profile optimize navigability delivery, may, in turn, broaden their range use. <h3>MATERIALS METHODS:</h3> Data from all consecutive patients...
Image quality and diagnostic reliability of T2-weighted MR images the cervical spine are often impaired by several kinds artifacts, even in cooperative patients. The aim this study was to evaluate if BLADE sequences might solve these problems a routine patient collective.TSE were compared 60 patients for sagittal imaging spine. sharpness, motion truncation metal CSF flow phenomena, contrast anatomic structures (vertebral body/disk, spinal cord/CSF), cord depiction evaluated 2 independent...

Time-resolved contrast-enhanced magnetic resonance angiography of the carotid arteries: diagnostic accuracy and inter-observer variability compared with selective catheter angiography. Invest Radiol 2002;37:535–541. Rationale Objectives. To assess interobserver (CE-MRA) in a time-resolved technique digital subtraction (x-ray DSA) patients suspected stenoses internal artery.

Flow diversion is a common endovascular treatment for cerebral aneurysms, but studies comparing different types of flow diverters are scarce.To perform propensity score matched cohort study the Pipeline Embolization Device (PED) and Redirection Intraluminal (FRED) posterior circulation aneurysms.Consecutive aneurysms treated at 25 neurovascular centers with either PED or FRED were collected. Propensity matching was used to control age, duration follow-up imaging, adjunctive coiling, aneurysm...
OBJECTIVE Well-documented case reports of the rapid formation and rupture de novo aneurysms posterior circulation are rare. CLINICAL PRESENTATION We report a patient with subarachnoid hemorrhage caused by an aneurysm anterior communicating artery that was clipped consecutively. Forty-four days after initial hemorrhage, experienced second newly grown basilar tip. Between two hemorrhages, transcranial Doppler sonography neuroimaging revealed fulminant generalized vasospasm. INTERVENTION To our...
<h3>BACKGROUND AND PURPOSE:</h3> Flow diversion for the posterior circulation remains a promising treatment option selected aneurysms. The Flow-Redirection Intraluminal Device (FRED) system has not been previously assessed in large cohort of patients with purpose present study was to assess safety and efficacy FRED this location. <h3>MATERIALS METHODS:</h3> Consecutive aneurysms treated at 8 centers participating European (EuFRED) between April 2012 January 2019 were retrospectively...
Abstract Purpose: To evaluate if the use of BLADE sequences might overcome some limitations magnetic resonance imaging (MRI) in extracranial head and neck, which is a diagnostically challenging area with variety artifacts broad spectrum potential lesions. Materials Methods: After informed consent Institutional Review Board approval, two different (BLADE IR) without inversion pulse (BLADE) were compared to turbo‐spin echo (TSE) fat saturation for coronal T1‐weighted postcontrast neck region...
Purpose The recent COVID-19 pandemic has resulted in an increasing overload of the medical system. Healthcare workers (HCW) radiology departments are exposed to a high infection risk similar HCWs ICU or dedicated COVID wards. goal our paper is evaluate prevalence IgG antibody against SARS-CoV-2 among two different hospitals and regions Germany with low compare it other clinical personnel. Additionally, we assessed number radiological procedures performed patients positive PCR test (C+)...

To evaluate the value of vascular ultrasound determining pre-interventional degree distal stenosis in extracranial internal carotid artery (ICA) by means color-coded duplex sonography (CCDS) and B-flow. Comparison with contrast-enhanced 64-line CT angiography (CTA), MRA (ceMRA) digital subtraction (DSA).Complementary diagnostics evaluation CCDS, B-flow, CTA, ceMRA DSA were performed prior to percutaneous stent-assisted PTA 21 symptomatic ICA stenosis. Ultrasound carried out high-resolution...
Ziel: In einer prospektiven Studie wurde untersucht, ob die kontrastmittelverstärkte MR-Angiographie der Becken- und Beinarterien ausreichende Informationen beinhaltet, um einen Verzicht auf Katheterangiographie zu rechtfertigen. Material Methode: einem Zeitraum von 23 Wochen wurden 100 konsekutive Patienten eingeschlossen. Bei diesen insgesamt 112 Untersuchungen durchgeführt. Die MRA erfolgte in Schrittverschiebetechnik bei 1,5 Tesla mit dedizierten Spulensystem. Es dokumentiert, welchen...
Since the beginning of COVID-19 pandemic, in-utero transmission SARS-CoV-2 remains a rarity and only very few cases have been proven across world. Here we depict clinical, laboratory radiologic findings preterm triplets born at 28 6/7 weeks to mother who contracted just 1 week before delivery. The showed positivity right after birth, developed significant leukopenia early-onset pulmonary interstitial emphysema. most severely affected triplet I required 10 days high-frequency oscillatory...
Bewusstseinsstörungen stellen sich in der Notfallsituation zunächst unspezifisch dar mit einer Vielzahl von möglichen Ursachen. Daher müssen die Informationen aus Anamnese, Inspektion, allgemeiner und neurologisch-klinischer Untersuchung, Labor- insbesondere zerebralen Bildgebung zu schlüssigen Arbeitsdiagnose zusammengeführt werden. Prognostisch entscheidend ist eine schnelle dennoch ausreichend differenzierte Diagnosestellung als Grundlage Therapie.
CT-guided thoracal sympathicolysis for the treatment of peripheral arterial occlusive disease and chronic pain syndromes in 6 patients.Retrospective evaluation safety effectivity percutaneous (CT-TSL) patients with (PAOD) upper limb syndromes.
