Decompression of the spinal canal in pediatric patients with achondroplasia can be accomplished safely with significant clinical benefit. Patients with a history of cervicomedullary compression may be at an increased risk of developing symptomatic stenosis prior to adolescence. Fusion procedures are recommended in patients with a large decompression overlying a thoracolumbar kyphosis to avoid progressive postoperative deformity.
Modern surgical devices and techniques have developed dramatically with the availability of new technologies. As a result, continual advancements have been achieved in intramedullary spinal cord tumor surgery, thus increasing the safety and effectiveness of tumor resection, and progressively improving the overall outcomes in patients undergoing such procedures.
Introduction: Antibiotic-impregnated shunt (AIS) components decrease shunt infections by preventing bacterial colonization that occurs during implantation. Despite studies showing improved efficacy in preventing infection however, concern still exists regarding using AIS components in infants, especially premature ones. In this study, clinical outcomes were assessed in infants with hydrocephalus (<1 year) following AIS placement. Methods: A prospective observational study was conducted involving pediatric patients <1 year of gestational age with hydrocephalus who underwent placement of AIS components (ventriculoperitoneal, ventriculoatrial, and cystoperitoneal) as initial treatments, shunt revision surgery, or following previous placement of a ventricular access device (VAD, Rickman reservoir). Measured outcomes included: infection, shunt revision surgery, and complications. Results: Seventy-four infants underwent 108 AIS procedures, and all were followed for over 9 months. Twenty-seven patients (36.5%) possessed previous VADs. Average weight and gestational age at birth were 1,976 g (range: 560–3,500 g) and 32.8 weeks (range: 23–41 weeks), respectively. The average age at the time of surgery was 14.6 weeks (range: 1 day to 50 weeks). Five infections occurred in 5 patients (4.6% of procedures, 6.75% of patients), 60% of which were very premature (<32 weeks). Thirty-three patients (44.6%) required shunt revision surgery, 5 (15%) for infection and 28 (85%) for malfunction. Three cerebrospinal fluid leaks occurred perioperatively without significant sequelae, and no mortalities occurred from the procedures. Conclusion: AIS systems can safely be used to treat hydrocephalus in pediatric patients <1 year old, even for those with a history of prematurity. One possible therapeutic application for such premature patients may be the incorporation of antibiotic impregnation into VADs or ventriculosubgaleal components to treat infants with hydrocephalus prior to definitive CSF shunt placement.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
