Abstract Background and introduction Information about optimal use of heparin in flush fluids during endovascular thrombectomy (EVT) for acute ischemic stroke (AIS) is lacking.

We aim to provide insight in these unknown but highly relevant variables. https://www.diegojavierfares.com/quick-grab-can-Ichnusa-Beer-1x33cl-best-save/
