Bridging May Increase the Risk of Symptomatic Intracranial Hemorrhage in Thrombectomy Patients With Low Alberta Stroke Program Early Computed Tomography Score

Johannes Kaesmacher, Thomas R. Meinel, Stefania Nannoni, Marta Olivé-Gadea, Eike I. Piechowiak, Christian Maegerlein, Martina Goeldlin, Laurent Pierot, David J. Seiffge, Vitor Mendes Pereira, Mirjam R. Heldner, Lorenz Grunder, Vincent Costalat, Marcel Arnold, Tomas Dobrocky, Jan Gralla, Pasquale Mordasini and Urs Fischer

Abstract Background and Purpose: Whether intravenous thrombolysis (IVT) increases the risk for symptomatic intracranial hemorrhage (sICH) in patients treated with mechanical thrombectomy (MT) is a matter of debate. Purpose of this study was to evaluate the extent of early ischemia as a possible factor influencing the risk for sICH after IVT+MT versus direct MT.

Adriaan C.G.M. van Es, Maayke A.W. Hunfeld, Ido van den Wijngaard, Ulrike Kraemer, Marc Engelen, Boudewijn A.A.M. van Hasselt, Puck S.S. Fransen, Diederik W.J. Dippel, Charles B.L.M. Majoie, Aad van der Lugt, Bart J. Emmer and for the MR CLEAN Registry Investigators

Abstract Background and Purpose: Multiple trials have shown the efficacy and safety of endovascular therapy (EVT) of acute ischemic stroke in adults. Trials in children are lacking and only case reports and case series exist. However, the long-term outcome of children with acute ischemic stroke can be devastating with significant mortality and morbidity. In this study, we describe the safety and efficacy of EVT in children with anterior circulation acute ischemic stroke who were included in the MR CLEAN Registry (Multicenter Randomized Clinical Trial of Endovascular Treatment for Acute Ischemic Stroke in the Netherlands).

Thrombus Composition and Efficacy of Thrombolysis and Thrombectomy in Acute Ischemic Stroke

Precious Jolugbo and Robert A.S. Ariëns

Abstract Thrombi retrieved from patients with acute ischemic stroke are highly heterogeneous. Recent data suggest that thrombus composition may impact on mechanical thrombectomy, the number of recanalization manoeuvres, resistance to retrieval, and on thrombolytic potential. Our aim was to summarize evidence describing the impact of thrombus composition on efficacy of mechanical thrombectomy and thrombolysis in patients with acute ischemic stroke. The scoping review methodology guided by the Joanna Briggs Institute, an adaption of the Arksey and O’Malley, was followed. Comprehensive searches were conducted in MEDLINE, EMBASE, SCOPUS, and Web of Science. Articles were classified into 4 key themes: (1) composition of stroke thrombi, (2) thrombus composition and mechanical thrombectomy, (3) thrombus composition and thrombolytic therapy, and (4) novel imaging and endovascular approaches. Our search identified 698 articles published from 1987 to June 2020. Additional articles were extracted from reference lists of the selected articles. Overall, 95 topic-specific articles identified for inclusion published in 40 different journals were included. Reports showed that thrombus composition in stroke was highly heterogeneous, containing fibrin, platelets, red blood cells, VWF (von Willebrand Factor), and neutrophil extracellular traps. Thrombi could roughly be divided into fibrin- and red blood cell–rich clots. Fibrin-rich clots were associated with increased recanalization manoeuvres, longer procedure time, and less favorable clinical outcomes compared with red blood cell–rich clots. Advances in detection or treatment of thrombi that take into account clot heterogeneity may be able to improve future endovascular and thrombolytic treatment of stroke.

Female Stroke, Sex Differences in Acute Treatment and Early Outcomes of Acute Ischemic Stroke

Anna K. Bonkhoff, André Karch, Ralph Weber, Jürgen Wellmann and Klaus Berger

Abstract Background and Purpose: Men and women are differently affected by acute ischemic stroke (AIS) in many aspects. Prior studies on sex disparities were limited by moderate sample sizes, varying years of data acquisition, and inconsistent inclusions of covariates leading to controversial findings. We aimed to analyze sex differences in AIS severity, treatments, and early outcome and to systematically evaluate the effect of important covariates in a large German stroke registry.

Absence of Consistent Sex Differences in Outcomes From Symptomatic Carotid Endarterectomy and Stenting Randomized Trials

Virginia J. Howard, Ale Algra, George Howard, Leo H. Bonati, Gert J. de Borst, Richard Bulbulia, David Calvet, Hans-Henning Eckstein, Gustav Fraedrich, Jacoba P. Greving, Alison Halliday, Jeroen Hendrikse, Olav Jansen, Martin M. Brown, Jean-Louis Mas, Peter A. Ringleb, Thomas G. Brott and on behalf of the Carotid Stenosis Trialists’ Collaboration

Background and Purpose: CREST (Carotid Revascularization Endarterectomy Versus Stenting Trial) reported a higher periprocedural risk for any stroke, death, or myocardial infarction for women randomized to carotid artery stenting (CAS) compared with women randomized to carotid endarterectomy (CEA). No difference in risk by treatment was detected for women relative to men in the 4-year primary outcome. We aimed to conduct a pooled analysis among symptomatic patients in large randomized trials to provide more precise estimates of sex differences in the CAS-to-CEA risk for any stroke or death during the 120-day periprocedural period and ipsilateral stroke thereafter.

Good Clinical Outcome Decreases With Number of Retrieval Attempts in Stroke Thrombectomy

Fabian Flottmann, Caspar Brekenfeld, Gabriel Broocks, Hannes Leischner, Rosalie McDonough, Tobias D. Faizy, Milani Deb-Chatterji, Anna Alegiani, Götz Thomalla, Anastasios Mpotsaris, Christian H. Nolte, Jens Fiehler and Máté E. Maros

Abstract Background and Purpose: Endovascular therapy is the standard of care in the treatment of acute ischemic stroke due to large-vessel occlusion. Often, more than one retrieval attempt is needed to achieve reperfusion. We aimed to quantify the influence of endovascular therapy on clinical outcome depending on the number of retrievals needed for successful reperfusion in a large multi-center cohort.

Stroke Imaging Selection Modality and Endovascular Therapy Outcomes in the Early and Extended Time Windows

Raul G. Nogueira, Diogo C. Haussen, David Liebeskind, Tudor G. Jovin, Rishi Gupta, Ashutov Jadhav, Ron F. Budzik, Blaise Baxter, Antonin Krajina, Alain Bonafe, Ali Malek, Ana Paula Narata, Ryan Shields, Yanchang Zhang, Patricia Morgan, Bruno Bartolini, Joey English, Michael R. Frankel, Erol Veznedaroglu and for the Trevo Registry and DAWN Trial Investigators

Abstract Background and Purpose: Advanced imaging has been increasingly used for patient selection in endovascular stroke therapy. The impact of imaging selection modality on endovascular stroke therapy clinical outcomes in extended time window remains to be defined. We aimed to study this relationship and compare it to that noted in early-treated patients.

Excess Cerebrovascular Mortality in the United States During the COVID-19 Pandemic

Richa Sharma, Lindsey R. Kuohn, Daniel M. Weinberger, Joshua L. Warren, Lauren H. Sansing, Adam Jasne, Guido Falcone, Amar Dhand and Kevin N. Sheth

Abstract Background and Purpose: The magnitude and drivers of excess cerebrovascular-specific mortality during the coronavirus disease 2019 (COVID-19) pandemic are unknown. We aim to quantify excess stroke-related deaths and characterize its association with social distancing behavior and COVID-19–related vascular pathology.

Cost-Effectiveness of Mechanical Thrombectomy for Treatment of Nonminor Ischemic Stroke Across Europe

Paolo Candio, Mara Violato, Jose Leal and Ramon Luengo-Fernandez

Abstract Background and Purpose: Mechanical thrombectomy (MT) has been recommended for the treatment of nonminor ischemic stroke by national and international guidelines, but cost-effectiveness evidence has been generated for only a few countries using heterogeneous evaluation methods. We estimate the cost-effectiveness of MT across 32 European countries.

CD31 Mimetic Coating Enhances Flow Diverting Stent Integration into the Arterial Wall Promoting Aneurysm Healing

Jonathan Cortese, Charlotte Rasser, Guillaume Even, Sylvia M. Bardet, Christine Choqueux, Jules Mesnier, Marie-Laure Perrin, Kevin Janot, Jildaz Caroff, Antonino Nicoletti, Jean-Baptiste Michel, Laurent Spelle, Giuseppina Caligiuri and Aymeric Rouchaud

Background and Purpose: Beyond aneurysmal occlusion, metallic flow diverters (FDs) can induce an adverse endovascular reaction due to the foreignness of metal devices, hampering FD endothelialization across the aneurysm neck, and arterial healing of intracranial aneurysms. Here, we evaluated the potential benefits of an FD coating mimicking CD31, a coreceptor critically involved in endothelial function and endovascular homeostasis, on the endothelialization of FDs implanted in vivo.
