Background: Endoscopic third ventriculostomy (ETV) is considered a safe procedure although it carries its rate of risks and complications that may occasionally be life-threatening.
Case report: This is a report about a 48-year-old woman presenting with progressive gait unsteadiness, weakness of the lower extremities and cognitive impairment due to tri-ventricular hydrocephalus. This was treated with standard ETV. In the immediate post-operative period the patient developed a severe and uncontrollable tachypnea requiring sedation, intubation and mechanical ventilation.
Conclusion: Tachypnea may be an early complication after standard ETV and although its mechanism remains yet unclear, we speculate that it may be related to excessive traction and/or surgical manipulation of the floor of the third ventricle. Supportive care with mechanical ventilation is the mainstay of treatment until spontaneous normalization of the respiratory mechanism occurs.
