Lumbo-omental shunt for drainage of cerebrospinal fluid in hydrocephalus.

A new cerebrospinal fluid (CSF) shunting procedure is presented. By transposing a pedicle graft of the greater omentum to the lumbar CSF compartment, the CSF absorption capacity of the omentum is utilized. The operation is applicable to the treatment of communicating hydrocephalus. The technical problems and physiological effects of the operation have been studied earlier in dogs. This paper presents the first case of an intended clinical series. The patient was studied for 18 months postoperatively by different examinations, including psychometric tests, cisternography, computer tomography, echo-ventriculography, and carotid angiography with measurement of the cerebral blood flow. A gradual improvement in his clinical state was registered after the operation.
