Abstract
Objective: Acute ischemic stroke (AIS) is a leading cause of death, but isolated middle cerebral artery dissection (MCAD) is rarely reported. The aim of this article is to sum up the current information on this pathology and to explore the technical aspects of its endovascular treatment with emphasis on novel coated, antithrombogenic stents and antiplatelet management. Another part of this article offers our experience with the problematics represented by a small sample group of patients with an MCAD diagnosis who were treated in our center. Methods: We conducted literature research and a retrospective review of patients treated for anterior circulation AIS at our comprehensive stroke center from January 2022 to March 2024. The cohort included 16 patients diagnosed with isolated MCAD, 9 received antithrombogenic coated stents, while 7 received bare metal stents. Pharmacological management of coated stents involved the use of Cangrelor for acute antiplatelet therapy, transitioning to oral Ticagrelor. Results: Among the 16 patients treated, those with antithrombogenic coated stents showed no major complications and had a lower incidence of intracranial hemorrhage compared to the bare metal stent group. The average National Institutes of Health Stroke Scale (NIHSS) score at discharge improved in both groups. Functional outcomes and mortality rates were slightly better in the coated stent group, but no statistical significance was proven. Conclusions: Antithrombogenic coated stents, in conjunction with MAPT, demonstrated a safe and effective option for treating isolated MCAD. These stents offer promising potential for improved outcomes and reduced complications compared to traditional treatments. Further multicentric studies with larger cohorts are recommended to validate these findings.
