COMPUTED TOMOGRAPHY ANGIOGRAPHY AND PERFUSION IMAGE CHARACTERISTICS IN PATIENTS WITH ACUTE ISCHEMIC STROKE AT CAN THO CENTRAL GENERAL HOSPITAL IN 2020-2022
Main Article Content
Abstract
Background: Computed tomography angiography (CTA) and perfusion (CTP) can provide information about the site of occlusion and tissue viability – the key to the treatment of acute ischemic stroke. Objectives: To describe CTA, CTP image characteristics and to find out some factors related to signs of acute ischemic stroke. Materials and methods: Prospective descriptive cross-sectional study of 39 patients treated at Can Tho Central General Hospital from 8/2020 to 5/2022. Results: Middle cerebral artery occlusion in 64.1%. CTP showed evidence of hypoperfusion in 87.2%. The NIHHS score was positively correlated with penumbra volume and was statistically significant between lesions ≥ 1/3 and <1/3 hemisphere. Conclusions: The results highlight the importance of CTA, CTP in diagnosis. The NIHSS score is a predictor of perfusion deficits and patients with low scores could also have artery occlusion
