Objective: Most large-vessel occlusions (LVOs) amenable to acute recanalization occur in the internal carotid or middle cerebral artery. However, few LVOs with a multivessel disease can be difficult to treat. This study aimed to determine the outcomes of mechanical thrombectomy in patients with both anterior and middle cerebral artery occlusions.Methods: We retrospectively collected data for patients who had undergone mechanical thrombectomy since January 2016 at Fukushima Medical University and its affiliated institutions (10 institutions). Patients with occluded vessels in the anterior and middle cerebral arteries were selected, and patient background, treatment course, and outcomes were reviewed.Results: A total of 341 mechanical thrombectomies were performed during the study period. Seven patients had occlusions involving both anterior and middle cerebral arteries. In these seven patients, the median time from onset to imaging, imaging to puncture, and puncture to recanalization was 106, 60, and 74 min, respectively. Only one patient (14%) had a modified Rankin Scale of 0–2 at 90 days.Conclusion: Comorbid anterior cerebral artery occlusion may worsen the outcome of patients with middle cerebral artery occlusion.
