The administration of rtPA before mechanical thrombectomy in acute ischemic stroke patients is associated with a significant reduction of the retrieved clot area but it does not influence revascularization outcome
Rossi, Rosanna; Fitzgerald, Sean; Molina, Sara; Mereuta, Oana Madalina; Douglas, Andrew; Pandit, Abhay; Santos, Andreia M. Silva; Murphy, Blathnaid; Alderson, Jack; Brennan, Paul; Power, Sarah; O'Hare, Alan; Gilvarry, Michael; McCarthy, Ray; Psychogios, Klearchos; Magoufis, Georgios; Tsivgoulis, Georgios; Nagy, Andras; Vadasz, Agnes; Szikora, Istvan; Jood, Katarina; Redfors, Petra; Nordanstig, Annika; Ceder, Erik; Dehlfors, Niclas; Dunker, Dennis; Tatlisumak, Turgut; Rentzos, Alexandros; Thornton, John; Doyle, Karen M. (Springer, 2020-09-16)Both intravenous thrombolysis (IVT) and mechanical thrombectomy (MT) are evidence-based treatments for acute ischemic stroke (AIS) in selected cases. Recanalization may occur following IVT without the necessity of further ... -
Correlation between acute ischaemic stroke clot length before mechanical thrombectomy and extracted clot area: Impact of thrombus size on number of passes for clot removal and final recanalization
Rossi, Rosanna; Fitzgerald, Seán; Molina Gil, Sara; Mereuta, Oana; Douglas, Andrew; Pandit, Abhay; Brennan, Paul; Power, Sarah; Alderson, Jack; O'Hare, Alan; Gilvarry, Michael; McCarthy, Ray; Psychogios, Klearchos; Magoufis, George; Tsivgoulis, Georgios; Szikora, Istvan; Jood, Katarina; Redfors, Petra; Nordanstig, Annika; Ceder, Erik; Tatlisumak, Turgut; Rentzos, Alexandros; Thornton, John; Doyle, Karen (SAGE Publications, 2021-07-07)Introduction We assessed the correlation between thrombus size before and after mechanical thrombectomy, measured as length by Computed Tomography Angiography/Non-Contrast Computed Tomography (CTA/NCCT) and Extracted Clot ... -
Fatty acid binding protein expression in clots retrieved by mechanical thrombectomy from patients with acute ischaemic stroke
Mereuta, Oana Madalina; Fitzgerald, Seán; Douglas, Andrew; Rossi, Rosanna; Silva Santos, Andreia M.; Pandit, Abhay; Thornton, John; O'Hare, Alan; Power, Sarah; Brennan, Paul; Rentzos, Alexandros; Tatlisumak, Turgut; Gunnarsson, Thorsteinn; Davidson, Maria; Brederlau, Anke; Allardt, Arne; Brinjikji, Waleed; Kallmes, David F.; Doyle, Karen M. (Sage Publications, 2019-05-22)Introduction: Lipid accumulation and inflammation are considered hallmarks of the unstable atherosclerotic plaque. In particular, adipocyte fatty acid binding protein (FABP4) expression within the plaque is associated ... -
The impact of occlusion location and bridging therapy in patients affected by acute ischemic stroke in determining the total number of passes required to remove the clot and the final revascularization outcome
Rossi, Rosanna; Fitzgerald, Seán; Mereuta, Oana Madalina; Douglas, Andrew; Pandit, Abhay; Szikora, István; Tsivgoulis, Georgios; Psychogios, Klearchos; Murphy, Blathnaid; Brennan, Paul; Power, Sarah; O'Hare, Alan; Thornton, John; Rentzos, Alexandros; Tatlisumak, Turgut; Doyle, Karen M. (WFITN (World Federation of Interventional and Therapeutic Neuroradiology), 2019-10-21)Purpose Our purpose was to assess the impact of occlusion location in patients suffering from Acute Ischemic Stroke (AIS) on the total number of passes (attempts) necessary to retrieve the clot and on final revascularization ... -
Platelet-rich emboli are associated with von Willebrand factor levels and have poorer revascularization outcomes
Douglas, Andrew; Fitzgerald, Seán; Mereuta, Oana Madalina; Rossi, Rosanna; O'Leary, Sean; Pandit, Abhay; McCarthy, Ray; Gilvarry, Michael; Holmegaard, Lukas; Abrahamsson, Margareta; Jerndal, Mikael; Dehlfors, Niclas; Brennan, Paul; Power, Sarah; O'Hare, Alan; Griffin, Emma; Kallmes, David F.; Brinjikji, Waleed; Szikora, István; Tatlisumak, Turgut; Rentzos, Alexandros; Thornton, John; Doyle, Karen M. (BMJ Publishing Group, 2019-11-04)Background and aims Platelets and von Willebrand factor (vWF) are key factors in thrombosis and thus are likely key components of acute ischemic stroke (AIS) emboli. We aimed to characterize platelet and vWF levels in AIS ...
