External ventricular drainage and cerebrospinal fluid shunt are two separate surgeries. Whether or not cerebrospinal fluid shunt surgery is practiced depends on whether or not there are indications for the surgery, and if there is obstruction of cerebrospinal fluid circulation, the surgery is feasible after removing contraindications.
External ventricular drainage is mainly used for the treatment of hypertensive cerebral hemorrhage and aneurysm rupture. Cerebrospinal fluid shunt surgery is mainly used for the treatment of cerebrospinal fluid circulation obstruction and hydrocephalus.
After cerebral hemorrhage is treated with external ventricular drainage, if there is a combination of obstructive hydrocephalus caused by an abnormal blood clot blocking the cerebrospinal fluid circulation pathway, it may be necessary to continue cerebrospinal fluid shunt surgery in order to relieve the increased intracranial pressure.
There are many types of cerebrospinal fluid shunt surgeries, and the most commonly used are ventriculoperitoneal shunt and ventriculoatrial shunt. However, it is important to note that shunt surgery is contraindicated in the presence of systemic or intracranial infections, or severe cardiopulmonary impairment that prevents the patient from tolerating surgery.
Whether or not to perform this surgery needs to be determined by the clinician based on the condition of the patient, and it is not mandatory to perform this surgery.
