Management of Chiari I Deformity in Children and Adolescents: A Report from the Consensus Taskforce of the Brazilian Society of Pediatric Neurosurgery

Much controversy remains on the current management of Chiari I deformity (CID) in children, with many clinical, surgical and ethic-legal implications. The Brazilian Society of Pediatric Neurosurgery (SBNPed, in the Portuguese acronym) has put together a panel of experts to analyze updated published data on the medical literature about this matter and come up with several recommendations for pediatric neurosurgeons and allied health professionals when dealing with CID. Their conclusions are reported herein, along with the respective scientific background.

Neuroendoscopic surgery in children: an analysis of 200 consecutive procedures / Neuroendoscopia em crianças: uma análise de 200 procedimentos consecutivos

Neuroendoscopic surgery in children has particular features and is associated with different success rates (SR). The aim of this study was to identify putative factors that could influence the outcome in pediatric patients.

Clinical data of 177 patients under 18 years of age submitted to 200 consecutive neuroendoscopic procedures from January 2000 to January 2010 were reviewed. The overall success rate was 77%. Out of the patients with successful outcomes, 46% were under six months, 68% were between six months and one year of age, and 85% older than one year. Neuroendoscopic techniques provide very good results for a wide number of indications in children. Tumor-related cerebrospinal fluid (CSF) circulation problems and aqueductal stenosis seem to be particularly well suited to neuroendoscopic treatment regardless of the patient's age. Patients' age and etiology of hydrocephalus were associated with a different outcome. In all cases, surgical experience is extremely important to reduce complications. .

A cirurgia neuroendoscópica em crianças apresenta particularidades e está associada a diferentes taxas de sucesso (TS). O objetivo deste estudo consistiu em identificar fatores que pudessem influir no resultado do tratamento em pacientes pediátricos. Dados clínicos de 177 pacientes com idade inferior a 18 anos submetidos a 200 procedimentos neuroendoscópicos consecutivos entre janeiro de 2000 e janeiro de 2010 foram revisados. A taxa de sucesso global foi de 77%. Os pacientes com idade inferior a seis meses apresentaram taxa de sucesso de 46%; pacientes entre seis meses e um ano de vida obtiveram êxito em 68% dos casos; dentre os maiores de um ano, 85% dos procedimentos foram bem-sucedidos. Técnicas neuroendoscópicas proporcionam muito bons resultados para uma grande variedade de indicações em crianças. Independentemente da faixa etária, o tratamento endoscópico apresenta-se particularmente adequado para problemas da circulação liquórica relacionados a tumores e à estenose aquedutal. A faixa etária dos pacientes e a etiologia da hidrocefalia estão associadas a diferentes resultados. Em todos os casos, experiência neurocirúrgica é extremamente importante para a redução das complicações. .
