intraventricular injection

Intraventricular injection involves delivering medication directly into the brain's ventricles, which are fluid-filled spaces that help cushion and protect the brain. This method allows targeted treatment of neurological conditions, such as infections or cancer, by bypassing the blood-brain barrier—a protective layer that can prevent drugs from reaching the brain when given through the bloodstream. A healthcare professional typically inserts a thin catheter or needle into one of the ventricles, often through a small hole in the skull, to administer the medication safely and precisely.
