Clinical and ultrasonographic criteria for using ventriculoperitoneal shunts in newborns with myelomeningocele.

Objective Hydrocephalus is one of the main complications associated with myelomeningocele (MM). This study aimed to identify clinical and ultrasonographic criteria for using ventriculoperitoneal (VP) shunts in this group of patients.Method A retrospective cohort study, based on established protocol for VP shunt implant in hydrocephalic children with MM. Parameters used to guide the indication of VP shunts included measurement of head circumference (HC), evaluation of fontanels, and measurement of lateral ventricular atrium (LVA) width by transcranial ultrasonography.Results 43 children were included in the analysis, of which 74% had hydrocephalus and required a VP shunt. These children had LVA width ≥ 15 mm, showed increased HC, or had bulging fontanels.Conclusion VP shunt is required in children with increased HC (≥ 2 standard deviation regarding age group), bulging fontanels, or LVA width of ≥ 15 mm after the closure of MM.

Objetivo Identificar os critérios clínicos e ultrassonográficos para a recomendação do implante de derivações ventrículo peritoneais (DVP) em neonatos portadores de mielomeningocele (MM).Método Estudo de coorte retrospectivo, com base no protocolo estabelecido para o implante de DVP em crianças com hidrocefalia associada a MM. Parâmetros utilizados para orientar a indicação de DVP incluíram a medida da circunferência craniana (CC), a avaliação das fontanelas e a medida da largura lateral do átrio ventricular (LAV), avaliado por ultrassonografia transcraniana.Resultados 43 crianças foram incluídas na análise, dos quais 74% tinham hidrocefalia com recomendações para uso de DVP.Conclusão O aumento da CC e o abaulamento de fontanelas foram os principais critérios para a indicação de DVP. A DVP é necessária em crianças com aumento da CC (≥ 2 desvios padrões para a idade), fontanelas abauladas, ou LAV ≥ 15 mm após o fechamento cirúrgico da MM.

Unusual spinal dysraphic lesions.

Human tail and multiple spinal dysraphism are unusual congenital malformations. Human tail appeared as a prominent lesion from the lumbosacrococcygeal region, generally without connection between the tail and the neurospinal axis. Spinal dysraphisms are usually isolated, reaching 0.038% of incidence of multiple spinal dysraphisms in the same child. There were three cases described of unusual spinal dysraphic lesions: two cases of human tail and a case of a multiple thoracic myelomeningocele. The literature about diagnosis and treatment was reviewed. Microsurgical technique was performed to provide better exploration of the lesions, and resection could be done in those congenital malformations, without morbidity.

Congenital hydrocephalus in the northeast of Brazil: epidemiological aspects, prenatal diagnosis, and treatment.

PURPOSE: Congenital hydrocephalus (CH) has higher proportions in developing countries such as Brazil, reaching rates of 3.16:1,000 newborns. Early diagnosis is essential and can be done during the second trimester of pregnancy, highlighting the importance of regular prenatal care. Our objective is to describe the epidemiological profile of children with CH in the state of Bahia. METHODS: Consecutive medical records of patients with CH, aged less than 2 years and operated at a pediatric reference hospital between September 2009 and September 2012, were reviewed. RESULTS: One hundred twenty-one children underwent ventricular peritoneal shunt (VP shunt) due to CH. As for prenatal care, 38% of pregnant women did it regularly. Males predominated with 56% of cases with a median age of 3 months, and 68% were from the countryside area. The most frequent clinical manifestations were bulging fontanelle (37%) and increased head circumference (30%). There were 13 (11%) reports of complications associated with VP shunts. There were nine deaths (7%), and respiratory complications were the main cause. CONCLUSIONS: Public health measures are the key to increase mothers' knowledge about the importance of regular prenatal monitoring. There was a predominance of male children, with a median age of 3 months, with the majority coming from the countryside.
