Abstract
Background: Stroke caused by middle cerebral artery (MCA) occlusion results in severe sequelae and a high risk of mortality. This study evaluates the roleof endovascular intervention and compares clinical and paraclinical characteristics of MCA occlusion at proximal and distal M1.
Materials and methods: Prospective study at Cho Ray Hospital from 01/2023 to 06/2024 on patients with MCA occlusion at M1 segment treated with endovascular intervention. Parameters assessed include lipid disorders, atrial fibrillation, mTICI score, recanalization time, NIHSS, and mRS at 90-day follow-up.
Results: Among 47 cases, successful recanalization (TICI 2b/3) was achieved in 93.62%, good clinical outcomes (mRS 0–2) in 51.06%, mortality was 21.28%, NIHSS averaged 17.72, and the mean recanalization time was 22.15 minutes. Distal M1 occlusion had a higher rate of atrial fibrillation compared to proximal M1 occlusion (56.52% vs. 12.50%), while proximal M1 occlusion had a higher prevalence of lipid disorders (80.95% vs. 50.00%).
Conclusion: Endovascular intervention for acute MCA occlusion at M1 segment achieves a high rate of successful recanalization and rapid recanalization time. Proximal M1 occlusion is associated with a higher prevalence of lipid disorders, whereas distal M1 occlusion is more frequently linked to atrial fibrillation.
