ABOUT STENT RETRIEVER THROMBECTOMY ACUTE ISCHEMIC STROKE THERAPIES
Stent retriever thrombectomy is the recommended standard of care for patients suffering acute ischemic stroke (AIS), the most common type of stroke.1 Ischemic stroke occurs when blood vessels carrying oxygen and nutrients to the brain are blocked by a clot, causing brain cells to die.
The 2015 update to the AHA/ASA guidelines for early management of patients with AIS now recommends the use of endovascular treatment with stent retrievers, following IV t-PA, for eligible patients.1
Large vessel occlusions (LVO), in particular, respond poorly to IV t-PA.2-3
The typical AIS patient loses 2 million neurons/min in the territory at risk7 but ischemic penumbra can be salvaged if the vessel is quickly recanalized.8
Successful recanalization is associated with:

A good prehospital assessment and routing system is imperative to improving patient outcomes and includes:
