[Postoperative respiratory alkalosis as a complication of neuroendoscopy].

Endoscopic neurosurgery is a minimally invasive technique that has been developing rapidly. It is mainly indicated for the treatment of hydrocephaly due to ventriculocisternostomy, biopsies of cerebral ventricular lesions, evacuation of cerebral hematomas and spinal surgery. Hemorrhage, infection and spinal fluid fistula are known complications. We report the appearance of symptomatic postoperative respiratory alkalosis in a patient who underwent ventriculocisternostomy by endoscopic neurosurgery. The underlying disease was obstructive hydrocephaly secondary to partial stenosis of the Silvius aqueduct.
