Article Synopsis
  • COVID-19 patients with acute ischemic stroke (AIS) exhibit thrombi that are rich in neutrophils and contain neutrophil extracellular traps (NETs), but lack the virus's spike protein.
  • A study comparing AIS thrombi from COVID-19 and non-COVID-19 patients found that both types displayed similar resistance to thrombolysis when treated with tissue-type plasminogen (tPA).
  • Adding DNase 1 enhanced the thrombolytic process for both groups, suggesting that COVID-19 does not affect NET content or the thrombi's resistance to fibrinolysis, which could help in treating such patients.

Background And Purpose: The Blood Pressure Target in Acute Ischemic Stroke to Reduce Hemorrhage After Endovascular Therapy (BP TARGET) trial evaluated whether an intensive systolic blood pressure (SBP) target resulted in reduced rates of intracranial hemorrhage (ICH) after successful endovascular therapy (EVT) but did not assess the effect of blood pressure variability (BPV) on functional outcomes and ICH occurrence. We sought to evaluate this question in the BP TARGET trial.

Methods: We performed a post hoc analysis of the BP TARGET trial and included patients with at least 50% of blood pressure (BP) recordings during the first 24 h after EVT.

Importance: Mechanical thrombectomy using a stent retriever or contact aspiration is widely used for treatment of patients with acute ischemic stroke due to anterior circulation large vessel occlusion, but the additional benefit of combining contact aspiration with stent retriever is uncertain.

Objective: To determine whether mechanical thrombectomy for treatment of anterior circulation large vessel occlusion stroke with initial contact aspiration and stent retriever combined results in better final angiographic outcome than with standard stent retriever alone.

Design, Setting, And Participants: This trial was a multicenter randomized, open-label, blinded end point evaluation that enrolled 408 patients from October 16, 2017, to May 29, 2018, in 11 French comprehensive stroke centers, with a 12-month outcome follow-up.

Immediate reocclusion after mechanical thrombectomy (MT) for acute ischemic stroke (AIS) is a rare but devastating condition associated with poor functional outcome. The aim of this study was to gain insights into the mechanisms underlying immediate reocclusion, and to evaluate the efficacy and safety of the glycoprotein IIb/IIIa antagonist abciximab, for its treatment. Clinical data were collected from April 2015 to April 2019 in a monocentric prospective registry of AIS patients treated by MT.

Background: High systolic blood pressure after successful endovascular therapy for acute ischaemic stroke is associated with increased risk of intraparenchymal haemorrhage. However, no randomised controlled trials are available to guide optimal management. We therefore aimed to assess whether an intensive systolic blood pressure target resulted in reduced rates of intraparenchymal haemorrhage compared with a standard systolic blood pressure target.
