Stress hyperglycemia is associated with futile recanalization in patients with anterior large vessel occlusion undergoing mechanical thrombectomy.

Stress hyperglycemia predicts FR in patients with successful recanalization after MT. Further studies should explore if managing stress hyperglycemia may reduce futile recanalization. Additionally, we recommend paying close attention to AIS patients with a GAR index greater than 24.8 who exhibit a high risk of FR.
