Ninety-four patients with hydrocephalus following subarachnoid haemorrhage were investigated. Fourteen of these patients had temporary ventricular drains inserted, 19 had drains that were later converted to ventricular-peritoneal shunts, and 61 patients had shunts only. All patients were analysed with respect to their grade on admission, the distribution of blood on CT scan, their Glasgow Coma Score, their intracranial pressure, and the presence or absence of vasospasm on angiography. ⋯ Vasospasm was not more common in patients requiring a ventriculo-peritoneal shunt, nor did early shunting in patients with hydrocephalus affect the incidence of vasospasm. The majority of patients were either shunted in the first three days or after 30 days post-SAH. The outcome was better in those patients shunted at a later date.

Retrogasserian glycerol injection or percutaneous stimulation in the treatment of typical and atypical trigeminal pain.
Of 164 patients with trigeminal neuralgia treated by percutaneous retrogasserian glycerol injections, we have studied the long-term outcome (one to four years) of 72 patients. 51 patients suffered from idiopathic trigeminal neuralgia, and of these 92% were freed from pain by the operation. 21 patients suffered from symptomatic trigeminal neuralgia due to multiple sclerosis or of traumatic or infectious origin. Of these, only 38% became free of pain. A further 8 patients with facial deafferentation pain who underwent treatment by retrogasserian neurostimulation with a permanently implanted electrode were included in this study. 4 of these patients were rendered free of pain by this procedure.
