Brain bleed breakthrough? new drug could stop fluid buildup without surgery

This early study tests whether a drug called sirolimus (rapamycin), given directly into the brain's fluid spaces, can prevent hydrocephalus after a severe brain hemorrhage. Hydrocephalus is a dangerous buildup of fluid that often requires a permanent surgical shunt. The trial will enroll 15 adults with bleeding from a ruptured aneurysm and will check safety, inflammation, and whether patients ultimately need a shunt.
