Abstract

Background: Stroke is the second leading cause of death worldwide. The burden of stroke lies not only in its high mortality and morbidity rates but also in the fact that 50% of survivors are left disabled. Stroke is mainly classified into two types: cerebral infarction and cerebral hemorrhage. Imaging diagnostics play a crucial role in determining the type of stroke, guiding treatment, and monitoring patients. Objective: To study the characteristics of multi-slice computed tomography in diagnosing anterior circulation infarction within 24 hours of symptom onset. Subjects and Methods: 130 patients diagnosed with acute cerebral infarction due to anterior circulation occlusion who were treated with mechanical thrombectomy at E Hospital. Describe the characteristics of brain and cerebral vascular on MSCT and evaluate the relationship between brain and cerebral vascular CT characteristics with some clinical features in patients with acute circulation infarction. Results: The male/female ratio was 1.55/1. Patients aged ≥60 accounted for the highest proportion at 73.9%, with hypertension being the most common risk factor at 54.6%. The signs of hypodensity of the lentiform nucleus and loss of insular ribbon were the two most common signs on non-contrast brain CT scans, with rates of 70% and 53.8% respectively. There was a statistically significant relationship between Glasgow Coma Scale, National Institutes of Health Stroke Scale (NIHSS), Medical Research Council (MRC) scale, and modified Rankin Scale (mRS) with the degree of collateral circulation (p < 0.05). Conclusion: Brain and cerebral vascular CT charateristics are valuable in diagnosing acute circulation infarction.
