Treatment of In-stent Restenosis of the Internal Carotid Artery Using Drug-eluting Balloons
ConclusionThe use of DEB angioplasty is a  safe and effective treatment of ICA ISR lesions, yielding significantly better results compared to other modalities. Randomized multicenter studies are warranted.

P124/272 Initial encounter with a cutting-edge mobile head CT scanner (Somatom On.site) in a neuro-intensive care unit
ConclusionThe study demonstrates the clinical effectiveness of modern mobile CT scanners in neurointensive care units. The Somatom On.site provides sufficient image quality, saves time and supports timely decision making. The integration of mobile CT scanners in NICUs improves patient care and workflow. Prospective studies are needed to validate these findings and assess the long-term impact in NICUs and other units, such as stroke units.Disclosure of InterestCK serves as consultants for Acandis GmbH (Pforzheim, Germany) and proctor for MicroVention Inc./Sequent Medical (Aliso Viejo, CA, USA).

Stroke Thrombectomy through Interstices of a Hybrid Endograft Placed for Type A Aortic Dissection
A 53-year-old man presented with acute, severe, thoracic pain, absence of the femoral and left radial pulses, and asymmetric blood pressure —80/40 mm Hg in the left arm and 170/110 mm Hg in the right arm. Contrast-enhanced computed tomography revealed type A aortic dissection, starting from the aortic valve and extending into both iliac arteries (Fig 1). Emergent hemiarch replacement surgery was performed, with insertion of a hybrid a ortic stent with a proximal felt sewing cuff (Ascyrus Medical Dissection Stent, [AMDS]; Ascyrus Medical, Frankfurt, Germany) into the aortic arch with reimplantation of the brachiocephalic ...

MRI for all: Cheap portable scanners aim to revolutionize medical imaging
.news-article__hero--featured .parallax__element{ object-position: 47% 50%; -o-object-position: 47% 50%; } The patient, a man in his 70s with a shock of silver hair, lies in the neuro intensive care unit (neuro ICU) at Yale New Haven Hospital. Looking at him, you’d never know that a few days earlier a tumor was removed from his pituitary gland. The operation didn’t leave a mark because, as is standard, surgeons reached the tumor through his nose. He chats cheerfully with a pair of research associates who have come to check his progress with a new and potentially revolutionary device they are testing. The cylind...

P92 Thrombectomy in ischemic stroke patients with extended lesion and time window
ConclusionVessel recanalization in patients with low ASPECTS and extended time window was associated with better functional outcomes in a time window up to 17.6h and ASPECTS of 3–5. The results of this study encourage current randomized trials investigating treatment of patients in the extended stroke lesion and time window.ReferencesNogueira RG, Jadhav AP, Haussen DC, et al.

Distribution of Diagnoses and Clinical and Imaging Characteristics in 1,322 Consecutive Suspected Stroke Patients
Conclusion: Our results help to plan resources in thrombectomy-capable centers in times of expanding indications for EVT where resources will have to be adjusted to patients with low-NIHSS, low-ASPECTS, and distal occlusions, and patients presenting in the extended time window, which may altogether account for an additional 20% of all ischemic stroke patients.

Diagnostic reference levels and median doses for common clinical indications of CT: findings from an international registry
ConclusionsDRLs for CTDIvol and DLP for EUCLID clinical indications from diverse organizations were established and can contribute to dose optimization. These values were usually significantly higher in the US than in Europe.Key Points•Registry data were used to create benchmarks for 10 common indications for CT identified by the European Society of Radiology.•Observed US radiation doses were higher than European for 9 of 10 indications (except chronic sinusitis).•The presented diagnostic reference levels and median doses highlight potentially unnecessary variation in radiation dose.

Structured Reporting of Acute Ischemic Stroke - Consensus-Based Reporting Templates for Non-Contrast Cranial Computed Tomography, CT Angiography, and CT Perfusion
CONCLUSION: Implementation of the structured template may increase quality and provide a minimum standard for radiological reports in patients with acute ischemic stroke.KEY POINTS: · The German Society of Radiology and the German Society of Neuroradiology are providing support for the development of structured templates in German.. · We present a template for the structured reporting of examinations of patients with acute ischemic stroke by non-contrast computed tomography, CT angiography, and CT perfusion. This template is provided on the website www.befundung.drg.de for free use.. · Implementation of the structured t...

Optimizing Patient Selection for Interhospital Transfer and Endovascular Therapy in Acute Ischemic Stroke: Real-World Data From a Supraregional, Hub-and-Spoke Neurovascular Network in Germany
Conclusion: Our findings show that hub-and-spoke neurovascular network infrastructures efficiently enable access to EVT to patients with AIS due to LAO, who are primarily admitted to PSCs without on-site EVT availability. As in real-world settings optimal allocation of EVT resources is warranted, teleconsultation by experienced endovascular interventionists and prompt interhospital-transfer-inquiries are crucial to reduce the futile transfer rates and optimize patient selection for EVT within neurovascular networks.

Evaluation of the interrater and intermethod agreement of the German multiparametric ultrasound criteria for the grading of internal carotid artery stenosis
ConclusionStrictly adhering to the multiparametric “DEGUM ultrasound criteria”, we found an excellent interrater agreement and a good intermethod agreement compared with angiography for the sonographic grading of extracranial ICAS. Thus, multiparametric CDS is in particular suitable for the follow up of extracranial ICAS even when examinations a re done by different sonographers.

“Accent issue”: foreign accent syndrome following ischemic stroke
In conclusion, FAS is a rare motor speech disorder, often related to cerebrovascular accidents involving critical regions in the dominant hemisphere. In addition, the present case adds further evidence to the role of the left primary motor cortex in modulation of prosody. In rare cases FAS can be the only sign of stroke or can appear after recovery from post-stroke aphasia.
