Stroke can also be held accountable for a ‘snowball effect’. In just a few years, it propelled rapid evolution and major technological advancements in stentrievers, aspiration and balloon catheters, and other devices. The landscape in the angiography suite also rapidly shifted. From long, dilligent procedures during which the most arduous and sometimes acrobatic challenge was safe catheterization of a ‘large intracranial vessel’, we are now expected and often able to catheterize an intracranial vessel, such an M2 branch, with a …
