Summary
Endoscopic third ventriculostomy is generally safe for hydrocephalus, but rare, fatal complications like subarachnoid hemorrhage can occur. Careful surgical technique is crucial to prevent vascular injury during this neurosurgical procedure.
Area of Science:
- Neurosurgery
- Neurology
- Medical Devices
Background:
- Endoscopic third ventriculostomy (ETV) is a standard treatment for noncommunicating hydrocephalus.
- ETV is typically considered a low-risk neurosurgical intervention.
- Rare complications associated with ETV necessitate continued vigilance and procedural refinement.
Purpose of the Study:
- To report a rare case of fatal subarachnoid hemorrhage (SAH) following ETV.
- To highlight the potential for severe complications despite the perceived safety of ETV.
- To emphasize the importance of precise anatomical landmarks during ETV to prevent vascular injury.
Main Methods:
- Case report of a 63-year-old male patient with obstructive hydrocephalus.
- Procedure involved endoscopic third ventriculostomy using a Fogarty balloon catheter.
- Postoperative assessment included computerized tomography (CT) scans and clinical evaluation.
Main Results:
- The patient developed severe perimesencephalic-peripontine subarachnoid hemorrhage (SAH) and progressive hydrocephalus post-ETV.
- Despite emergency intervention with external ventricular drainage, the patient experienced a fatal outcome.
- CT scans confirmed the presence of SAH and worsening hydrocephalus.
Conclusions:
- While ETV is generally safe, severe and fatal complications, such as SAH, can occur.
- Meticulous technique, including midline perforation of the third ventricle floor between specific anatomical landmarks, is essential to minimize vascular injury.
- Awareness of potential ETV complications is critical for neurosurgical practitioners.
