DOI: 10.1007/s00234-021-02651-9
Abstract: Endovascular thrombectomy (EVT) improves clinical outcomes in ischemic stroke with large vessel occlusion. Clinical benefits are inversely proportional to size of the pre-treatment ischemic core. This study compared estimated ischemic core volumes by two different… read more here.

DOI: 10.1038/s41598-020-73280-0
Abstract: We aimed to study the relationship between the ischemic core’s (IC) radiological hypodensity and the risk of parenchymal haematoma after endovascular therapy (EVT) in acute ischemic stroke (AIS) presenting > 4.5 h from onset. We studied AIS… read more here.

DOI: 10.1136/neurintsurg-2019-snis.127
Abstract: Background and purpose Computer Tomography Perfusion (CTP) is a useful tool in the evaluation of acute ischemic stroke, where it can provide an estimate of the ischemic core and the ischemic penumbra. The optimal CTP… read more here.

DOI: 10.1136/neurintsurg-2021-018239
Abstract: Background Sanguinate, a bovine PEGylated carboxyhemoglobin-based oxygen carrier with vasodilatory, oncotic and anti-inflammatory properties designed to release oxygen in hypoxic tissue, was tested to determine if it improves infarct volume, collateral recruitment and blood flow… read more here.

DOI: 10.1136/neurintsurg-2021-018490
Abstract: Background Proper identification of infarct extent is crucial for thrombectomy and prognostication. We sought to study the frequency and topographic aspects of those cases in which CT perfusion (CTP) misses a core lesion that is… read more here.

DOI: 10.1161/strokeaha.118.023407
Abstract: Background and Purpose— The effect of leptomeningeal collaterals for acute ischemic stroke patients with large vessel occlusion in the late window (>6 hours from last known normal) remains unknown. We sought to determine if collateral… read more here.

DOI: 10.1161/strokeaha.123.042689
Abstract: BACKGROUND Evaluating the extent of ischemic change is an important step in deciding whether to use thrombolysis or mechanical thrombectomy, but the current standard method, Alberta Stroke Program Early CT Score, is semiquantitative and has… read more here.
