- Abstract
Background: Shunt failure is an undesirable but common occurrence following neurosurgical shunting for pediatric hydrocephalus. Little is known about the occurrence of failure in lower-middle income country (LMIC) settings in South America. The objective of this study was to evaluate shunt failure in the sole publicly funded pediatric hospital in La Paz, Bolivia, with limited resources., Methods: A retrospective review of all patients at the Children's Hospital of La Paz, Bolivia (Hospital del Niño "Dr. Ovidio Aliaga Uria"), was conducted to identify all patients whose index surgical shunting for hydrocephalus was performed between 2019 and 2023. Categorical, continuous, and shunt failure data were statistically summarized., Results: A total of 147 unique pediatric patients underwent index ventriculoperitoneal shunting for hydrocephalus in the study period. There were 90 (61%) male and 57 (39%) female patients, with a median age of 2.2 months at index shunting procedure. The most common surgical indications were congenital hydrocephalus (n = 95, 65%), followed by hydrocephalus secondary to congenital defect (n = 25, 17%) and tumor (n = 18, 12%). A total of 18 (12%) of patients experienced inpatient failure during index admission requiring surgical revision at a median time of 12.5 days after index shunting. Postoperative imaging (OR 2.97, P = 0.037) and postoperative infection (OR 3.26, P = 0.032) during index admission both independently and statistically predicted inpatient failure. Of the 96 patients (65%) with postoperative follow-up, 16 (n = 16/96, 17%) patients experienced outpatient failure requiring readmission to hospital and surgical revision at a median time of 3.7 months after discharge. Kaplan-Meier estimations of overall inpatient and outpatient failure in this cohort were 23% (95% CI 14-37) and 28% (95% CI 15-49), respectively., Conclusions: Both inpatient and outpatient shunt failures are significant complications in the management of pediatric hydrocephalus in La Paz, Bolivia. We identify multiple avenues to improve these outcomes which are institution-specific based on the review of these failures. Lessons learnt may be applicable to other similarly resourced institutions across South American LMICs., (© 2024.
