Ventriculocavostomy (from Latin ventriculus - ventricle and vena cava - vena cava + ancient Greek stoma - hole) is an operation consisting of creating a communication between the cerebral ventricle and the vena cava in order to drain cerebrospinal fluid and reduce intracranial pressure.
This operation is performed for occlusive hydrocephalus, when there is an obstruction to the outflow of cerebrospinal fluid from the ventricles of the brain. Creating a communication between the ventricle and the vena cava allows the cerebrospinal fluid to flow into the venous bed, bypassing the site of obstruction.
Ventriculocavostomy may be performed as a temporary or permanent measure to reduce intracranial pressure and prevent brain damage. This is a palliative operation that can be used until the true cause of the disturbance in the outflow of cerebrospinal fluid is eliminated.
Ventriculomastostomy is a procedure in which the cavity of the ventricle of the brain and the pericardial space are connected. Often patients have impaired heart function and are registered with a cardiologist. Due to the connection of the ventricle and atria, the heart rhythm is fixed,
