After a large ischemic stroke, swelling inside the skull can dangerously raise pressure and damage brain tissue. Decompressive hemicraniectomy helps by removing a section of the skull, giving the swollen brain room to expand, reducing pressure, and preventing further injury. This timely intervention can save lives and significantly lower the risk of severe, long-term disability. 🧠 Hear Dr. Symeon Missios explain how this procedure transforms stroke outcomes at the 3rd Annual Conference of Advances in Comprehensive Stroke Care — click the link to listen!
