Quantitative assessment of the ischemic damage to the brain parenchyma in patients with acute cerebrovascular accident using the Olea Sphere automated software

Objective: To evaluate the capabilities of Olea Sphere automated software for quantitative assessment ischemic damage to brain parenchyma during computed tomography (CT) in patients with acute cerebrovascular accident and its role choosing optimal treatment strategy everyday clinical practice. Materials methods: We retrospectively analyzed data from 129 suspected stroke who underwent perfusion CT within 24 hours admission hospital. The were used assess volume infarct core, which was defined as an area a relative cerebral blood flow less than 40%, penumbra area, where Tmax exceeded 6 s, ultimately core-penumbra ratio. Results: With software, we able changes parenchyma, particularly, average core 21.95 (1-206) ml, 57.01 (2-357) ratio 2.65, mean time start 1.2 (0.9-1.9) hours. This processing powered by provided indications following endovascular stroke: thrombus extraction period performed 51 (72.8%), transluminal balloon angioplasty stent placement – 12 (17.1%), carotid endarterectomy long-term 5 (9.6%) patients. Conclusions: discovered that can be make decisions related emergency conditions.
