Outcomes of Fenestration of Lamina Terminalis for Hydrocephalus following Clipping of Ruptured Aneurysms of Anterior Circulation

Reducing the likelihood of shunt-dependent hydrocephalus after ruptured aneurysm clipping can be achieved using lamina terminalis fenestration, regardless of fisher grade. It assists in preventing excessive brain retraction, decreasing intracranial pressure, raising brain perfusion, cisternal blood cleansing, and lowering the need for a ventriculoperitoneal shunt in cases of persistent hydrocephalus. Consequently, to reduce the incidence of shunt-dependent hydrocephalus, we recommend routine lamina terminalis fenestration following anterior circulation aneurysm clipping.
