Summary
Endoscopic third ventriculostomy (ETV) offers a 69% success rate for treating obstructive hydrocephalus in pediatric patients previously shunted. This neurosurgical procedure is a viable alternative to shunt revision, even in complex cases.
Area of Science:
- Neurosurgery
- Pediatric Neurology
Background:
- Obstructive hydrocephalus requires timely intervention.
- Ventriculoperitoneal (V-P) shunts are a common treatment but can fail.
- Endoscopic third ventriculostomy (ETV) is an alternative therapeutic option.
Purpose of the Study:
- To evaluate the success rate of ETV in pediatric patients with obstructive hydrocephalus who had prior V-P shunt implantation.
- To assess the feasibility of V-P shunt removal after successful ETV.
Main Methods:
- A retrospective study of 42 pediatric patients who underwent ETV between 2001 and 2011 after V-P shunt implantation.
- V-P shunts were temporarily clipped during ETV; removal was considered if clinical status and stoma function were favorable at 3 months.
- Magnetic resonance imaging (MRI) was used to confirm ventricular system obstruction.
Main Results:
- ETV was successful in 29 out of 42 patients (69%).
- V-P shunt removal was possible in successful cases.
- Two serious complications (4.7%) occurred, including delayed ETV failure leading to mortality in two patients.
Conclusions:
- ETV is a successful treatment for obstructive hydrocephalus, even in patients with a history of V-P shunt placement.
- ETV should be considered the primary endoscopic approach for obstructive hydrocephalus, offering a potential alternative to shunt revision.
- MRI can identify candidates for ETV during V-P shunt evaluation.
