The Frequency of Substantial Salvageable Penumbra in Thrombectomy‐ineligible Patients with Acute Stroke

Abstract

Even in the modern stent retriever era, 1 in 6 AIS patients presents with substantial penumbra judged not appropriate for ET. This population may benefit from the development of alternative therapies, including collateral enhancement, neuroprotection, and thrombectomy devices deployable in distal arteries.
