Summary

Awake endoscopic third ventriculostomy (ETVS) is a successful neurosurgical procedure for hydrocephalus in cooperative adults. This technique, using a flexible endoscope, offers a valuable alternative with no intraoperative complications.

Area of Science:

  • Neurosurgery
  • Neurology
  • Medical Technology

Background:

  • Hydrocephalus management often requires neurosurgical intervention.
  • Endoscopic third ventriculostomy (ETVS) is a minimally invasive option.
  • Evaluating awake procedures under local anesthesia is crucial for patient selection.

Purpose of the Study:

  • To analyze the experience and efficacy of awake endoscopic third ventriculostomy (ETVS) in hydrocephalic patients.
  • To assess the safety and feasibility of ETVS performed under local anesthesia.
  • To identify optimal techniques and patient profiles for successful awake ETVS.

Main Methods:

  • A retrospective analysis of 24 ETVS procedures performed under local anesthesia (bupivacaine and lidocaine) between September 1994 and December 2001.

  • Utilized a free-hand technique with a flexible endoscope in patients with primitive and secondary hydrocephalus.
  • Analgesics were administered based on patient response, with anesthesiologist assistance.

    • Main Results:

    • Successful ETVS was achieved in all 24 cases without procedure discontinuation due to seizures, bleeding, or agitation.
    • No intraoperative complications occurred; two asymptomatic trajectory hematomas were incidentally found postoperatively.
    • Dural incision/coagulation and Fogarty dilatation were identified as the most painful steps, sometimes requiring additional analgesia.

    Conclusions:

    • Awake ETVS is a safe and effective alternative for adult patients with hydrocephalus who can cooperate.
    • The free-hand technique with a flexible endoscope, performed efficiently with anesthesiologist support, is key to success.
    • Careful patient selection and procedural optimization are essential for this minimally invasive approach.
