Evaluation of mechanical thrombectomy in acute ischemic stroke related to a distal arterial occlusion: A randomized controlled trial.

Rationale: Mechanical thrombectomy (MT) associated with the best medical treatment (BMT) has recently shown efficacy for the management of acute ischemic stroke (AIS) secondary to a large vessel occlusion. However, evidence is lacking regarding the benefit of MT for more distal occlusions.

Aim: To evaluate the efficacy in terms of good clinical outcome at 3 months of MT associated with the BMT over the BMT alone in AIS related to a distal occlusion.

Early ischemic recurrence in acute spontaneous cervical artery dissection.

Background And Purpose: Early ischemic recurrence (EIR) following the diagnosis of acute spontaneous cervical artery dissection (CeAD) has been little investigated. We aimed to determine the prevalence and determinants on admission of EIR in a large single-center retrospective cohort study of patients with CeAD.

Methods: EIR was defined as any ipsilateral clinical or radiological cerebral ischemia or intracranial artery occlusion, not present on admission and occurring within 2 weeks.

Practical Nomogram Predicting Apixaban or Rivaroxaban Concentrations from Low-Molecular-Weight Heparin Anti-Xa Values: Special Interest in Acute Ischemic Stroke Patients.

Background And Purpose: In patients with acute ischemic stroke (AIS) using a direct oral factor-Xa anticoagulant (DOAC) during the last 48 hours, a fixed plasma heparin-calibrated anti-Xa activity (0.5 IU/mL) was proposed as a threshold below which patients could be eligible for thrombolysis and/or thrombectomy. Besides, specific DOAC-calibrated anti-Xa thresholds up to 50 ng/mL have been proposed.

Global Impact of the COVID-19 Pandemic on Stroke Volumes and Cerebrovascular Events: A 1-Year Follow-up.

Background And Objectives: Declines in stroke admission, IV thrombolysis (IVT), and mechanical thrombectomy volumes were reported during the first wave of the COVID-19 pandemic. There is a paucity of data on the longer-term effect of the pandemic on stroke volumes over the course of a year and through the second wave of the pandemic. We sought to measure the effect of the COVID-19 pandemic on the volumes of stroke admissions, intracranial hemorrhage (ICH), IVT, and mechanical thrombectomy over a 1-year period at the onset of the pandemic (March 1, 2020, to February 28, 2021) compared with the immediately preceding year (March 1, 2019, to February 29, 2020).
