title: [A case of ruptured aneurysm in a patient over 90 years of age, successfully treated by clipping with the use of a one-way ball valve for cisternal drainage].
abstract: The authors report a case of ruptured aneurysm in a patient in her 90's who was treated by clipping and returned to her independent life after discharge. A 91-year-old woman with a diagnosis of SAH of Hunt & Kosnik Grade III was treated using a conventional clipping operation with cisternal drainage. The cisternal drainage was assembled as a closed system using a newly developed one-way ball valve to regulate the CSF outflow. With this system the patient was able to take any posture and do any movement she wished, not being obligned to stay in bed. Early postoperative rehabilitation was able to be started to prevent pneumonia and muscular atrophy. The drainage was stopped on the 27th postoperative day when the CSF became clear. During the period of drainage, neither valve obstruction nor meningitis was noted. This valve system allows patients under cisternal drainage to move freely. It would be useful, especially when dealing with the elderly, to prevent unwanted complications often caused by postoperative restraint imposed by confinement to bed.
