Data about the coronavirus disease 2019 (COVID-19) pandemic's collateral damage on ischemic stroke (IS) care during the second epidemic wave in Central Europe are limited. We sought to evaluate the impact of the COVID-19 outbreak on Hungarian IS care during the two epidemic waves. This retrospective observational study was based on a nationwide reimbursement database that encompasses all IS admissions and all reperfusion interventions, i.

Aims: Our aim was to study the effectiveness of coronary stent implantation during the endovascular treatment (EVT) of acute basilar artery occlusion (BAO) with occlusion-underlying intracranial atherosclerotic stenosis (ICAS).

Methods And Results: We retrospectively analysed 91 consecutive BAO patients who underwent EVT between February 2014 and January 2019 in a single, high-volume neurointerventional centre. We studied the effect of immediate coronary stent implantation on the clinical outcome of BAO with occlusion-underlying stenosis.

Aim: The determination of the necessary capacity and number of neurology wards of level III progressivity that can be defined in the system of criteria detailed in this article and which possess optimal operating conditions in Hungarian terms.

Methods: We used the National Health Insurance Company's database to calculate case numbers and capacity for different levels of neurological and stroke care. We also revised the allocation of advanced diagnostic and therapeutic technologies, and proposed changes, based on health insurance data.

Background And Purpose: Intraventricular clot secondary to brain hemorrhage has still one of the worst prognosis among all stroke subtypes, regardless of conservative therapy or surgical interventions. The rapid clot resolution with thrombolytic agents could improve the outcome by restoring the impaired cerebrospinal fluid circulation, for this reason, the authors examined the safety and efficacy of Urokinase therapy in a randomized, controlled study.

Methods: They enrolled 27 patients with severe intraventricular hemorrhage between 1998 and 2002.

The aim of our study was to compare subtype-specific incidence rates, case-fatality rates and outcome predictors in different geographical areas, and decide what drives the variations. Analyzing standardized, prospective stroke registers in the Akita Prefecture, Japan, and in Hungary with catchment areas of more than 1.2 and 1.

Introduction: The authors summarised their experiences of systemic intravenous thrombolysis using recombinant tissue-type plasminogen activator with 3 hours therapeutic window in acute ischaemic stroke.

Aim: The aim of this work was to test the safety and efficacy of systemic thrombolysis in our unselected, community-based patient population.

Results: The mean door-to-needle time was 45 minutes, the number of bleeding complications and successful recanalisation was similar to the results of the large international trials.

Aim And Methods: In an open, observational study, 40 consecutive ischemic stroke patients eligible for thrombolytic therapy using the combined ECASS/NINDS inclusion criteria have been treated intravenously with 1.5 M units of streptokinase. The therapeutic window was 3 hours or shorter.

Introduction: In spite of all similarities, ischemic stroke cases representing 80% of the acute cerebrovascular accidents, different steps of platelet activation, coagulation and fibrinolytic cascade are involved in the pathomechanism of the different stroke subtypes. The differentiation of the atherothrombotic, cardioembolic and lacunar forms of acute ischemic stroke is based on the comprehensive evaluation of clinical signs, neuroimaging technics, and diagnostic ultrasound, but also a significant effort was made to characterize the specificities of the underlying processes of the coagulation system by signal molecules, in order to clarify their possible role and to support the diagnostic and therapeutic decisions.

Patients And Methods: The von Willebrand factor was studied as the marker of endothelial injury in 34 acute ischemic stroke patients within 24 hours after the onset of their stroke, and repeatedly 2, 4, and 12 weeks thereafter.
