Edward PY - 2024 T2 - External Ventricular and Lumbar Drains: Indications, Procedures, and Patient Care AB - CHAPTER SUMMARYTo understand the use of external ventricular drains (EVDs) and lumbar drains (LDs), one must be comfortable with the ventricular anatomy and cerebrospinal fluid (CSF) flow. Obstructive hydrocephalus is a state in which CSF flow is blocked within the ventricular system, whereas communicating hydrocephalus occurs when a blockage develops outside of the ventricular system. The indications for EVDs and LDs have expanded over the years beyond treating hydrocephalus. These drains are now used to monitor intracranial pressure and to treat CSF leak, delayed cerebral ischemia, intraventricular hemorrhage, central nervous system infection, and spinal cord reperfusion.
