Distension of the operation site after posterior fossa surgery.
In 130 posterior fossa operations 6 cases of progressive distension of the operation site have been recorded and documented. The possible causes of this complication and the surgical management are discussed. Isotope studies after injection of Ytterbium 169DTPA into the underlying cyst have shown abnormal patterns in CSF circulation and absorption. All the cases have resolved after ventriculo-peritoneal shunts.
