Journal ArticleDOI
Endovascular Coiling Versus Neurosurgical Clipping for Patients With Aneurysmal Subarachnoid Hemorrhage
I.C. van der Schaaf,A. Algra,M.J.H. Wermer,A Molyneux,Mike Clarke,J Van Gijn,G. J. E. Rinkel +6 more
TL;DR: There is firm evidence that, if the aneurysm is considered suitable for both surgical clipping and endovascular treatment, coiling is associated with a better outcome.
Journal ArticleDOI
CT after subarachnoid hemorrhage: relation of cerebral perfusion to delayed cerebral ischemia.
I.C. van der Schaaf,M.J.H. Wermer,Y. van der Graaf,Reinier G Hoff,G. J. E. Rinkel,B. K. Velthuis +5 more
TL;DR: The cerebral blood flow ratio (comparing contralateral regions of interest) seems the best prognosticator for development of DCI.
Journal ArticleDOI
Data-efficient deep learning of radiological image data for outcome prediction after endovascular treatment of patients with acute ischemic stroke.
Adam Hilbert,Lucas A. Ramos,H. J. A. van Os,Silvia D. Olabarriaga,Manon L Tolhuisen,M.J.H. Wermer,Renan Sales Barros,I.C. van der Schaaf,Diederik W.J. Dippel,Yvo B.W.E.M. Roos,W.H. van Zwam,Albert J Yoo,Bart J. Emmer,G. J. Lycklama à Nijeholt,Aeilko H. Zwinderman,Gustav J. Strijkers,Charles B. L. M. Majoie,Henk A. Marquering +17 more
TL;DR: Deep Learning techniques for building models to directly predict good reperfusion after endovascular treatment (EVT) and good functional outcome using CT angiography images are investigated and automated image analysis with Deep Learning methods outperforms radiological image biomarkers for stroke outcome prediction and has the potential to improve treatment selection.
Journal ArticleDOI
Assessment of Collateral Status by Dynamic CT Angiography in Acute MCA Stroke: Timing of Acquisition and Relationship with Final Infarct Volume.
I. R. van den Wijngaard,Ghislaine Holswilder,M.J.H. Wermer,Jelis Boiten,A. Algra,Diederik W.J. Dippel,J.W. Dankbaar,Birgitta K. Velthuis,Anne M. M. Boers,Charles B. L. M. Majoie,M.A.A. van Walderveen +10 more
TL;DR: Dynamic CTA provides a more detailed assessment of collaterals than single-phase CTA and has a stronger relationship with infarct volume at follow-up and the extent of collateral flow is more important in determining tissue fate than the velocity of collateral filling.
Journal ArticleDOI
Risk factors for atherosclerotic and medial arterial calcification of the intracranial internal carotid artery.
Annelotte Vos,Remko Kockelkoren,Jill B. De Vis,Jill B. De Vis,Yvonne T. van der Schouw,Irene C. van der Schaaf,Birgitta K. Velthuis,Willem P.Th.M. Mali,Pim A. de Jong,Charles B. L. M. Majoie,Yvo B.W.E.M. Roos,L.E. Duijm,Koos Keizer,A. van der Lugt,Diederik W.J. Dippel,K.E. Droogh-de Greve,Henri Paul Bienfait,M.A.A. van Walderveen,M.J.H. Wermer,G. J. Lycklama à Nijeholt,Jelis Boiten,D.A. Duyndam,Vincent I H Kwa,Frederick J. A. Meijer,E.J. van Dijk,F.O. Kesselring,Jeannette Hofmeijer,Jan Albert Vos,Wouter J. Schonewille,W.J. van Rooij,P.L.M. de Kort,C. Constantijn Pleiter,S. L. M. Bakker,Mayken Visser,B.K. Velthuis,I.C. van der Schaaf,J.W. Dankbaar,W. P. T. M. Mali,T. van Seeters,Alexander D. Horsch,Joris M. Niesten,Geert Jan Biessels,L. J. Kappelle,Merel J A Luitse,Y. van der Graaf +44 more
TL;DR: Risk factors are differently related to the dominant localizations of calcifications, a finding that supports the hypothesis that the intimal and medial calcification represents a distinct etiology.
