Objective: Simultaneous anterior cerebral artery (ACA) and middle cerebral artery (MCA) occlusion is rare. We investigated the clinical and radiological outcomes of patients with simultaneous ACA and MCA occlusion treated with mechanical thrombectomy.
Methods: We analyzed the clinical and radiological outcomes of 12 patients with simultaneous ACA and MCA occlusion treated with mechanical thrombectomy from January 2018 to December 2020. The clinical outcome was assessed using the modified Rankin Score (mRS) after 3 months of thrombectomy. The radiological outcome was assessed using the thrombolysis in cerebral infarction (TICI) score.
Results: The median National Institutes of Health Stroke Scale score at hospital arrival was 18 (interquartile range, 16–20). M1 was the most common occlusion lesion (n=8), and A3 was the most common lesion in the ACA (n=6). Six patients were first treated for MCA occlusion and later for ACA occlusion (MCA group). Other patients were first treated for ACA occlusion and later for MCA occlusion (ACA group). There was no difference in clinical outcomes between the MCA and ACA groups (p=0.180). Successful recanalization (TICI ¡Ã2b) of MCA was achieved in 10 patients (83.3%). Successful recanalization of ACA was achieved in 10 patients (83.3%). Successful recanalization of both ACA and MCA occlusion was observed in eight patients (66.7%). Three patients (25%) had good clinical outcomes (mRS ¡Â2).
Conclusions: In our series, simultaneous ACA and MCA occlusion showed relatively poor successful recanalization rates and poor clinical outcomes despite treatment with mechanical thrombectomy.
