Ventriculoperitoneal shunt outcomes among infants

Area of Science:

• Pediatric Neurosurgery
• Medical Device Outcomes
• Hydrocephalus Management

Background:

• Ventriculoperitoneal shunts (VPSs) are a primary treatment for hydrocephalus in infants.
• Shunt failure and infection are significant complications impacting patient outcomes.
• Identifying risk factors for VPS failure is critical for improving treatment efficacy.

Purpose of the Study:

• To analyze the outcomes of VPS placements in infants.
• To determine the specific risk factors associated with shunt failure in this population.
• To identify early indicators for potential VPS complications.

Main Methods:

• Retrospective analysis of 24 infants undergoing initial VPS placement between March 2005 and January 2014.
• Kaplan-Meier curves were used to assess shunt survival rates.
• Multivariate Cox regression analysis was performed to identify independent risk factors for shunt failure.

Main Results:

• The study included 24 infants with a total of 45 shunt procedures.
• Shunt failure occurred at a rate of 0.51 per shunt, with infection rates at 0.13 per shunt.
• Infants younger than one month at the time of VPS placement showed a significantly increased risk of shunt failure (adjusted HR 17.56, p=0.001).

Conclusions:

• Age less than one month at the time of initial VPS placement is a significant risk factor for shunt failure in infants.
• Head circumference above the 90th percentile was also identified as a potential risk factor, though less significant in multivariate analysis.
• These findings underscore the importance of considering patient age in the management of pediatric hydrocephalus and VPS implantation.
