In a retrospective study, the intra- and early postoperative data of 39 children with 46 operations for craniopharyngioma were analyzed. Diabetes insipidus (DI) occurred in 30 out of 32 cases without preoperative evidence of DI. We observed that all children who did not have a pituitary stalk preserved and 5 out of 7 patients with preserved pituitary stalk developed DI within 18 h of surgery. Short-term inappropriate secretion of antidiuretic hormone (SIADH) occurred in 2 children, but was quickly followed by DI. The time of onset of DI and SIADH did not correlate with sex, age, body weight, location of tumor, or duration or extent of surgery. Parenteral desmopressin was an effective treatment for intra- and postoperative DI. The duration of the clinical effect of desmopressin administration varied in different patients between 4 and 23 h. An approach to the immediate intra- and postoperative management of children with craniopharyngioma is presented.

We report on a 31-year old pregnant patient with von-Hippel-Lindau syndrome who presented to the emergency room with symptoms of increased intracranial pressure. She was found in premature labour with a normal foetus of 29 weeks' gestational age in breech presentation. We discuss an anaesthetic and neurosurgical management during emergent craniotomy and Caesarean section. Caesarean section and posterior fossa craniotomy with resection of an angioblastoma are performed in one setting. Following rapid sequence induction with thiopentone and succinylcholine, anaesthesia is maintained with fentanyl, flunitrazepam and pancuronium; nitrous oxide and volatile anaesthetics are avoided. The advantages of this technique include haemodynamic stability and maintenance of intracranial pressure. Neonatal depression is likely with this technique and requires resuscitative measures. The indications for rapid sequence induction in pregnant patients with raised intracranial pressure at risk for aspiration are discussed. Different options for monitoring during this procedure are described.
