Frequency of Thrombectomy in Early and Late Postonset Time Windows Among Emergency Medical Services Patients With Acute Ischemic Stroke.

ABSTRACT:

Background

With recent trials demonstrating benefit of endovascular thrombectomy (EVT) up to 24 hours from last known well time (LKWT), emergency medical services systems must consider stroke center routing for patients with LKWT ≤24 hours. We sought to determine the frequency of thrombectomy by prehospital-determined LKWT using retrospective data from a tiered regional stroke care system.

Methods

During the July 2018 to March 2019 study period, patients with potential large-vessel occlusion, based on a Los Angeles Motor Scale of 4 or 5, were routed directly to a designated EVT center if within 30 minutes. We determined the frequency of thrombectomy by time intervals from prehospital-determined LKWT to first medical contact.
