Abstract Background and Purpose— The clinical course of acute ischemic stroke with large vessel occlusion (LVO) is a multifactorial process with various prognostic factors. We aimed to model this process with machine learning and predict the long-term clinical outcome of LVO before endovascular treatment and to compare our method with previously developed pretreatment scoring methods.
Abstract Background and Purpose— Parenchymal hematoma (PH) is a rare but dreadful complication of acute ischemic stroke with unclear underlying mechanisms. We aimed to study the incidence and predictors of PH after mechanical thrombectomy.
Abstract Background and Purpose— Flow diverter technology improvements are necessary to provide safe and good results and enable the treatment of a larger variety of aneurysms. We report a nationwide experience with the Derivo Embolization Device in the treatment of intracranial aneurysms.
The goal of stroke treatment is to minimize the amount of brain damage resulting from ischemia or hemorrhage in the cerebrovascular network. Some standard acute-phase interventions—tPA (tissue-type plasminogen activator) and mechanical thrombectomy—exist for ischemic stroke with dramatically improved outcomes.1,2 For hemorrhagic stroke, the interventions3 focus on stabilizing temperature and blood pressure and aggressively managing and preventing complications, including rising intracranial pressure and cerebral edema. Ongoing clinical trials4 are investigating pharmacological agents and early removal of the hematoma.
Reversible cerebral vasoconstriction syndrome (RCVS) is used to describe a multitude of pathologies encompassing the clinical terms Call-Fleming syndrome, thunderclap headache (TCH) with reversible vasospasm, benign angiopathy of the central nervous system, postpartum angiopathy, migrainous vasospasm or migraine angiitis, drug-induced cerebral arteritis or angiopathy, and sexual headache.
Abstract Background and Purpose— Emergent carotid artery stenting plus mechanical thrombectomy is an effective treatment for acute ischemic stroke patients with tandem occlusion of the anterior circulation. However, there is limited data supporting the safety of this approach in patients treated with prior intravenous thrombolysis (IVT). We aimed to investigate the safety of emergent carotid artery stenting-mechanical thrombectomy approach in stroke patient population treated with prior IVT.
Abstract Background and Purpose— The high prevalence of hyperintense acute reperfusion marker (HARM) seen after endovascular therapy is suggestive of blood-brain barrier disruption and hemorrhage risk and may be attributable to multiple thrombectomy passes needed to achieve recanalization.
Abstract Background and Purpose— Intravenous administration of heparin during endovascular treatment for ischemic stroke may improve outcomes. However, risks and benefits of this adjunctive therapy remain uncertain. We aimed to evaluate periprocedural intravenous heparin use in Dutch stroke intervention centers and to assess its efficacy and safety.
Abstract Background and Purpose— It has been hypothesized that in stroke patients, complete reperfusion (modified Thrombolysis in Cerebral Infarction; mTICI 3) after a single thrombectomy pass is a predictor for favorable outcome (modified Rankin Scale score, 0–2), but a true first-pass effect defined as improved clinical outcome after complete reperfusion with one versus multiple passes has not yet been specifically addressed in the literature.
Abstract Background and Purpose— The treatment of patients with acute ischemic stroke has been revolutionized by endovascular mechanical thrombectomy (MT), leading to dramatically improved outcomes. Here, we analyzed the impact of recent changes in stroke management on nationwide trends in patient characteristics, treatment modalities, and outcomes.
Abstract Background and Purpose— We aimed to evaluate the current practice patterns, safety and outcomes of patients who receive endovascular therapy (EVT) having mild neurological symptoms
Abstract Background and Purpose— Thrombus imaging characteristics have been reported to be useful to predict functional outcome and reperfusion in acute ischemic stroke. However, conflicting data about this subject exist in patients undergoing endovascular treatment. Therefore, we aimed to evaluate whether thrombus imaging characteristics assessed on computed tomography are associated with outcomes in patients with acute ischemic stroke treated by endovascular treatment.
Abstract Background and Purpose— Oral angioedema (OA) is a rare but life-threatening complication in patients with ischemic stroke receiving intravenous thrombolysis with r-tPA (recombinant tissue-type plasminogen activator). This study intended to determine associations between thrombolysis-related OA and ischemic stroke lesion sites using a voxel-wise lesion analysis.
Abstract Background and Purpose— Chronic cerebral hemodynamic impairment due to high-grade occlusive carotid disease may lead to compromised energy metabolism. This might result in chronic subtle tissue damage, even in patients without overt brain infarction. The aim of this study was to investigate hypoperfusion-related changes of cerebral energy metabolism and their potential restitution after revascularization. For this purpose, 3-dimensional 31P magnetic resonance spectroscopy and oxygenation-sensitive T2′ magnetic resonance imaging were used (with 1/T2′=1/T2*−1/T2), which were expected to cross-validate each other.
Abstract Background and Purpose— Substantial proportion of patients who achieve successful recanalization of acute ischemic stroke due to large vessel occlusion do not achieve good functional outcome. We aim to analyze the effect of number of thrombectomy device passes and degree of the recanalization (by modified Thrombolysis in Cerebral Infarction) on the clinical and functional outcome.
