Description
Nicole Khezri and colleagues identify who bleeds into damaged brain tissue after a clot-removal procedure for stroke, in a 2026 global registry study. Hemorrhagic transformation worsens outcomes after thrombectomy, and its subtypes behave differently. The team analyzed 1,453 patients with blocked front-brain arteries treated in a first-pass device registry, comparing scans a day after treatment and modeling risk factors for each bleeding pattern.
Four in ten patients showed some bleeding on imaging, though only a small share, just over three percent, had symptoms from it. Diabetes, severe stroke scores, and high blood sugar at arrival raised the overall risk, while a healthy early scan score and having atrial fibrillation lowered it. Specific scan and sugar patterns predicted particular subtypes. The authors urge trials to report bleeding by subtype, since lumping them hides who is truly at risk.
