NEUROLOGICAL DEFICIT DYNAMICS IN ISCHEMIC STROKES FOLLOWING ENDOVASCULAR THROMBOEXTRACTION

Abstract

The study analyzes the clinical dynamics of neurological deficits in patients with ischemic stroke following endovascular thromboextraction. A total of 140 patients aged 41–79 years with ischemic stroke in the carotid and vertebrobasilar systems were examined between 2022 and 2024 at the Neurology Department of the Republican Scientific Center for Emergency Medical Care. The patients were divided into two equal groups: the main group (70 patients) underwent emergency X-ray endovascular thromboaspiration, while the comparison group (70 patients) received standard therapy without thromboextraction. The neurological status was assessed using the NIHSS scale, and functional outcomes were evaluated using the modified Rankin Scale. Results demonstrated a statistically significant improvement in neurological and functional recovery in the main group. The Rankin Scale scores decreased from 4.6 ± 0.7 to 1.9 ± 0.3, while in the comparison group—from 4.8 ± 0.4 to 4.2 ± 0.7. Similarly, NIHSS scores in the main group improved from 22.17 to 6.47 (p < 0.005), indicating a marked reduction in neurological deficit, whereas changes in the comparison group were less pronounced (from 23.47 to 18.61). The findings confirm that emergency X-ray endovascular thromboaspiration ensures faster and more complete recovery of neurological function in ischemic stroke patients, reducing the degree of post-stroke disability.
