Ommaya reservoir, also known as Ommaya shunt, is a device consisting of an intraventricular catheter connected to a reservoir (port) implanted beneath the scalp. It is used for intrathecal administration of medication such as chemotherapy (mainly in the treatment of meningeal lymphomas, but also for other meningeal pathology) and palliative analgesics, as well as for CSF aspiration.
It can also be used for aspirating large cystic brain tumours as part of combination therapy. 1
- subdural haematoma or hygroma 2
- perforation of ventricular wall 3
- leucoencephalopathy secondary to administered medication 4
- a case of cavum septi pellucidi development due to shunt placement was reported 5
History and etymology
