Highlights

• Among 349 ischemic stroke patients treated by MT, 103 (30%) patients had ICH (20 symptomatic and 83 asymptomatic).
• A high NIHSS score and low ASPECTS were independent risk factors for ICH.
• Asymptomatic ICH was associated with poor clinical outcome at 90 days after stroke onset.

Whether asymptomatic intracranial hemorrhage (ICH) affects the clinical outcomes in patients with acute large vessel occlusion treated with mechanical thrombectomy (MT) remains unclear. This study aimed to address this uncertainty.

Asymptomatic ICH was defined as ICH without symptomatic ICH defined by the SITS-MOST criteria. A favorable outcome was defined as an mRS score ≤ 2 at 90 days after stroke onset.
