Abstract
Introduction: Hydrocephalus is characterized by the accumulation of cerebrospinal fluid (CSF) in the cerebral ventricular system, leading to increased intracranial pressure and dilatation of the ventricles. In children, it is manifested by irritability, accelerated growth of the head circumference, and signs of intracranial hypertension. Ventriculoperitoneal shunt (PVD) is a common surgical technique for CSF drainage. Objective: To analyze the complications associated with PVD in pediatric patients, identifying risk factors, patterns of occurrence, and clinical outcomes, to improve care and clinical outcomes. Methodology: An integrative review was carried out in consultation with PubMed and SciELO. Descriptors such as "ventriculoperitoneal shunt," "complications," "hydrocephalus," "infection," and "malfunction" were used. Articles from the last five years, in Portuguese and English, addressing complications of PVD were included. Out-of-scope, full-text, and duplicate studies were excluded. A total of 11 articles were selected for analysis. Results: We included 11 articles that highlighted complications such as infections, device malfunctions, obstructions, and abdominal complications. Shunt infections occur in up to 15% of pediatric cases, often within the first 6 to 12 months postoperatively. Distal catheter malfunction is common and requires frequent surgical revisions. Rare complications include abdominal pseudocysts, distal catheter extrusion, and gram-negative bacterial infections, with high rates in the first few days after shunt insertion. Frequent revisions increase the risk of complications. Conclusions: PVD, although effective, has several complications that impact the quality of life of pediatric patients. Infections and system malfunctions are the most common complications. Multidisciplinary management and preventive strategies are essential to optimize clinical outcomes and quality of life for patients.
