Objective: To explore the value of whole-brain perfusion parameters combined with multiphase computed tomography angiography (MP-CTA) in predicting the hemorrhagic transformation (HT) of ischemic stroke. Methods: A total of 64 patients with ischemic stroke who underwent noncontrast computed tomography, computed tomography perfusion imaging, and computed tomography angiography before treatment from August 2017 to June 2019 were included retrospectively. The perfusion parameters cerebral blood volume (CBV), cerebral blood flow (CBF), time to peak (TTP), mean transit time (MTT), time to maximum (Tmax), and permeability surfac...

CONCLUSIONS: Compared with RAPID, the Vitrea default setting was noninferior for patients with interventions and superior in penumbra estimation for patients without interventions as indicated by mean infarct differences and correlations with final infarct volumes.

CONCLUSION: A high level of CEUS perfusion and increased serum FFA levels are indicative of vulnerable carotid plaques, which may be useful for the prediction of stroke in patients with carotid artery disease. PMID: 32039838 [PubMed - as supplied by publisher]

Abstract Cerebral ischemia/reperfusion injury (CI/RI) is a common feature of ischemic stroke, involving a period of impaired blood supply to the brain, followed by the restoration of cerebral perfusion through medical intervention. Although ischemia and reperfusion brain damage is a complex pathological process with an unclear physiological mechanism, more attention is currently focused on the neuroinflammatory response of an ischemia/reperfusion origin, and anti-inflammatory appears to be a potential therapeutic strategy following ischemic stroke.

ConclusionOur everyday clinical practice experience suggests 9.8  % of consecutive AIS patients present in the 4.5–9 h window and 2.2 % adhere to EXTEND neuroimaging eligibility criteria for IVT. Only 1.3% of AIS is eligible for IVT according to EXTEND neuroimaging and clinical eligibility criteria.

Abstract Stroke is one of the world's most deadly pathologies, and the rate of stroke recurrence is high. However, due to the complex nature of ischemia and reperfusion injury, there is presently no reliable treatment. The main factors driving brain damage from ischemic stroke are neuronal cell death resulting from oxidative stress, inflammation, and failure of the blood brain barrier. While under normal conditions, the blood brain barrier acts as a selectively permeable membrane allowing solutes and other substances to pass into the tissues of the central nervous system, ischemia and reperfusion alter the express...
