Objectives: This study aimed to examine nationwide trends in acute stroke endovascular thrombectomy (EVT) following five pivotal trials in 2015 that established it as the 'standard of care'.

Methods: The Japanese Registry of NeuroEndovascular Therapy 4 was a nationwide retrospective study registering consecutive patients who underwent neurointervention by specialists certified by the Japanese Society for Neuroendovascular Therapy at 166 centers from January 2015 to December 2019. We extracted patients who underwent EVT, and analyzed the annual trends in baseline characteristics, revascularization procedures and outcomes.

Article Synopsis
  • The study examines trends in antithrombotic therapy during neuroendovascular procedures in Japan, analyzing data from the JR-NET 4 registry covering 36,560 cases from 2015 to 2019.
  • It found that the use of dual antiplatelet therapy (DAPT) significantly increased over the years, while monotherapy decreased; postprocedural anticoagulant therapy was notably discontinued.
  • Additionally, complications related to ischemic events rose slightly, and the occurrence of severe adverse events was higher in patients receiving more extensive preprocedural therapy.

Article Synopsis
  • This study evaluated the safety and effectiveness of the Versi Retriever for mechanical thrombectomy in patients suffering from acute ischemic stroke (AIS) at 10 hospitals in Japan.
  • It involved 58 patients, showing that 62% achieved a good recovery (mRS 0-2) after 90 days, and 100% had successful blood flow restoration.
  • The procedure had an 8% mortality rate within 90 days and a significant occurrence of intracranial hemorrhage, indicating that while effective, some risks are involved.

Article Synopsis
  • Endovascular treatment (EVT) shows promise for addressing extracranial vertebral artery (VA) stenosis, but optimal procedures and efficacy are still unclear.
  • A study analyzed data from 308 patients in Japan who underwent EVT, focusing on procedural success and outcomes at 30 days post-treatment.
  • Results indicated a high procedural success rate (98%) and functional independence (80%) without significant differences based on type of treatment used, highlighting EVT's potential but also the need for additional research.

Background And Objectives: Endovascular treatment (EVT) for medium vessel occlusion (MeVO) raises concern about hemorrhagic complications; however, its clinical impact has not been elucidated. Therefore, we investigated the association between intracranial hemorrhage (ICH) after EVT for MeVO and functional outcomes.

Methods: We conducted a post hoc analysis of the Japan Registry of NeuroEndovascular Therapy 4, a nationwide registry in Japan from 2015 to 2019 including 13 479 patients who underwent EVT for acute ischemic stroke.
