Post-Thrombectomy Mild Hypercapnia State Prevents Poor Outcome by Reducing Infarct Progression.

Objective: In endovascular therapy (EVT) for stroke, futile recanalization contributes to poor prognosis. Mild hypercapnia may enhance cerebral blood flow and prevent ischemia, but its impact on prognosis in successfully recanalized EVT patients is unclear.

Methods: We retrospectively analyzed 237 patients from the INSPIRE database who underwent successful recanalization at our center (October 2018-March 2022).
