Abstract

Objective: To describe the clinical and paraclinical characteristics and evaluate the early outcomes of mechanical thrombectomy in patients with acute ischemic stroke due to middle cerebral artery occlusion. Subjects and Methods: This was a prospective, interventional descriptive study without a control group, conducted on 83 patients diagnosed with acute ischemic stroke due to middle cerebral artery occlusion. All patients were treated at the Intensive Care Unit of Military Hospital 175 from December 2023 to December 2024. Results: The mean age was 67.4 ± 13.2 years, with 53% of patients being male. The most common comorbidities included hypertension (60.2%), atrial fibrillation (34.9%), and diabetes mellitus (15.7%). The predominant clinical presentations were hemiparesis (92.8%), central facial palsy (83.1%), and speech disorders (75.9%), with a mean NIHSS score of 18.1 ± 5.6. Imaging findings revealed that the M1 segment was the most frequent occlusion site (73.5%). The rate of complete recanalization (mTICI 3) was 59.0%, while the overall rate of successful recanalization (mTICI 2b–3) reached 87.9%. Favorable functional outcomes (mRS 0–2) were observed in 42.2% of patients at discharge and increased to 61.5% at 90 days. The most common complication was distal embolization (25.3%). Conclusion: Mechanical thrombectomy for acute ischemic stroke due to middle cerebral artery occlusion achieved a high rate of clinically significant recanalization (87.9%) and favorable functional outcomes at 90 days (61.5%), with a low complication rate, primarily distal embolization (25.3%).
