Ventriculoperitoneal Versus Lumboperitoneal Shunt for Post-Hemorrhagic Hydrocephalus: A Multicenter Analysis

Area of Science:

• Neurosurgery
• Neurology
• Medical device research

Background:

• Post-hemorrhagic hydrocephalus (PHH) management often involves shunts.
• The long-term efficacy of ventriculoperitoneal shunt (VPS) versus lumboperitoneal shunt (LPS) for PHH is not definitively established.
• Identifying risk factors for shunt failure is crucial for optimizing treatment strategies.

Purpose of the Study:

• To compare the long-term efficacy and safety of VPS versus LPS in adult patients with PHH.
• To identify specific risk factors associated with shunt failure for both VPS and LPS.

Main Methods:

• Retrospective cohort study of 273 adult PHH patients (2014-2018) across four tertiary centers.
• Primary outcome: 3-year shunt failure rate. Secondary outcomes: complications, Evans index, modified Rankin Scale (mRS).
• Univariate and multivariate logistic regression analyses were used to identify risk factors for shunt failure, stratified by shunt type.

Main Results:

• VPS demonstrated a significantly lower 3-year shunt failure rate (15.3%) compared to LPS (27.1%) (p=0.018).
• Favorable outcomes (mRS ≤ 3) were more frequent with VPS (86.4%) than LPS (72.9%) (p=0.006).
• Overdrainage was more common with LPS (12.5% vs. 5.1%, p=0.028). Independent risk factors for VPS failure included time from hemorrhage to surgery, elevated CSF protein, and low CSF glucose. For LPS, CSF red blood cells predicted failure.

Conclusions:

• VPS appears to offer superior long-term efficacy and a lower risk of overdrainage for PHH compared to LPS.
• Distinct risk factor profiles for shunt failure exist for VPS and LPS, necessitating tailored pre-operative considerations.
• Further research may refine shunt selection criteria based on individual patient risk factors.
