Research Article: Efficacy and safety of successful mechanical thrombectomy in elderly patients with anterior circulation large vessel occlusion acute ischemic stroke

Date Published: 2025-09-10

Abstract:
To explore the efficacy and safety of successful mechanical thrombectomy (MT) in elderly patients with anterior circulation large vessel occlusion acute ischemic stroke (AIS). A retrospective analysis was conducted on 437 patients admitted to our hospital from January 2019 to November 2023 who received successful MT because of anterior circulation large vessel occlusion AIS. They were divided into an elderly group (age ? 80?years old) and a young group (age<80?years old). Their clinical data were analyzed. There were 61 cases in the elderly group and 376 cases in the young group. Before and after propensity score matching analysis, there was no significant difference in any type of cerebral hemorrhage, cerebral hernia, futile recanalization and all-cause mortality between two groups of patients with a p value greater than 0.05. The incidence of any type of cerebral hemorrhage, cerebral hernia, futile recanalization and all-cause mortality in elderly patients with anterior circulation large vessel occlusion AIS was similar to that in young patients. Compared to young patients, MT is also effective and safe in elderly patients.

Introduction:
AIS with large vessel occlusion has a high rate of mortality and disability ( 1 ). MT had been proved to be one of the most effective methods for treating large vessel occlusion AIS ( 2 ). With the increasing aging of the population, about 30% of patients with AIS with anterior circulation large vessel occlusion were older than or equal to 80?years old ( 3 ). As the time window for MT treatment was further extended ( 4 , 5 ), more elderly patients with AIS with large vessel occlusion will receive MT treatment ( 6…
