Patient Pathways During Acute in-Hospital Stroke Treatment: A Qualitative Multi-Method Study
Discussion:Our results show that most direct staff-patient interactions are focussed within one phase, with a smaller number of interactions extending to other phases, and no professional (group) with direct patient interactions cover more than two phases of the acute stroke pathway. Future research should investigate how the pathways described here are experienced from the patient perspective, including how the organisation of visible care processes may influence patient satisfaction. Findings can be translated to accessible patient information resources as well as input for digitalisation efforts, provider orientation an...

Quality benchmarks for chest pain units and stroke units in Germany.
CONCLUSION: As reimbursement for emergency medicine in Germany was recently rearranged, quality benchmarking has gained incremental importance. Mandatory joint quality measurement in both concepts ensuring gap analysis and process improvement is encouraged. PMID: 31970463 [PubMed - as supplied by publisher]

Diagnostic and treatment standards for cerebral sinus venous thrombosis : Results of an online survey of German stroke units.
CONCLUSION: The survey revealed substantial homogeneity between RSUs and SRSUs and standards are mostly in line with the guidelines. Non-established procedures, such as invasive therapeutic procedures and the administration of new oral anticoagulants were used significantly more often in SRSUs.

Comparison of porcine and human vascular diameters for the optimization of interventional stroke training and research
This study aimed to determine a porcine weight group, in which the arterial diameters most closely match human cerebral artery diameters, and thus optimize the porcine in-vivo model for neuroendovascular purposes. A group of 42 German Landrace swine (45–74 kg) was divided into four subgroups according to their weight. Angiographic images of the swine were used to determine the arterial diameter of the main branches of the subclavian artery: axillary artery, brachial artery, exter nal thoracic artery, subscapular artery (at two different segments), suprascapular artery, caudal circumflex humeral artery, thoracodorsal arte...

Impact of ongoing intravenous thrombolysis until completion of endovascular treatment in large vessel occlusion stroke patients
ConclusionOur findings suggest that ongoing IVT until ET completion has a favorable impact on both clinical and angiographic outcomes, as well as on periprocedural conditions, regardless of the overall time intervals involved. Therefore, rapid ET after IVT should be sought in order to take advantage of the additive effect of ongoing IVT during ET. Future studies should consider IVT timing in the context of ET as a potential confounder and treatment target.

Stenosis Length and Degree Interact With the Risk of Cerebrovascular Events Related to Internal Carotid Artery Stenosis
Conclusion: We found a statistically insignificant tendency for the ultrasound-measured length of sICAS<70% to be longer than that of sICAS≥70%. Moreover, the ultrasound-measured length of sICAS<90% was significantly longer than that of sICAS 90%. Among patients with sICAS≥70%, the degree and length of stenosis were inversely correlated. Larger studies are needed before a clinical implication can be drawn from these results. Introduction Internal carotid artery stenosis (ICAS) causes around one-fifth of ischemic cerebrovascular stroke and has the highest risk of early stroke recurrence...

Correlation Between Intracranial Arterial Calcification and Imaging of Cerebral Small Vessel Disease
Conclusion: Intracranial artery calcification is common in patients with ischemic cerebrovascular disease and the intracranial carotid artery is most frequently affected. Intracranial arterial calcifications might be associated with imaging markers of SVD and are highly correlated with WMHs, lacunes, and CMBs. Quantification of calcification on CT provides additional information on the pathophysiology of SVD. Intracranial arterial calcification could act as a potential marker of SVD. Introduction Atherosclerosis is a systemic vascular process that is considered a major cause of cerebrovascular and cardiovascular di...

Mechanical Thrombectomy in Isolated Occlusion of the Proximal Posterior Cerebral Artery
Discussion: EVT in isolated PCAO appears safe and feasible. Positive effects on clinical outcome are primarily on ENI but also depend on the initial stroke severity. Further prospective or randomized studies are needed to better describe the potential long-term clinical benefits of EVT for PCAO as compared with best medical management.

Plasma Metal Concentrations and Incident Coronary Heart Disease in Chinese Adults: The Dongfeng-Tongji Cohort
Conclusions: Our study suggested that incident CHD was positively associated with plasma levels of titanium and arsenic, and inversely associated with selenium. Additional research is needed to confirm these findings in other populations. https://doi.org/10.1289/EHP1521 Received: 22 December 2016 Revised: 17 September 2017 Accepted: 19 September 2017 Published: 19 October 2017 Address correspondence to T.

E-040 Flat panel imaging of occlusion site and collateral scores for emergent large vessel occlusion
Conclusion FP-CTA correlates well with standard CTA in determining site of occlusion and CS in the setting of ELVO. This angiographic tool may have potential applications for both triage and patient selection of patients with ELVO. Disclosures L.

Imaging of Spontaneous and Traumatic Cervical Artery Dissection
ConclusionNeuroradiologists should be aware that intimal flaps and multivessel dissections are more common after a traumatic etiology. In addition, it seems important to conduct a  CTA in a trauma setting, even if no cervical spine fracture is detected.

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.
