Early surgical excision provides effective treatment of huge encephaloceles. Overall, 21% of cases require cerebrospinal fluid (CSF) diversion afterward depending on associated anomalies. Despite their size, giant encephaloceles can have an excellent prognosis with no need for further treatment or CSF diversion.
Aim:In this study, we were assessing the outcome of Endoscopic Third Ventriculostomy (ETV) in infants below six months of age in cases of congenital obstructive hydrocephalus.Materials and Methods:The study was done prospectively on eight cases of obstructive hydrocephalus in infants younger than six months of age to assess the success rate of ETV as a primary treatment for hydrocephalus in this age group; in cases of evident failure, a ventriculo-peritoneal (VP) shunt was applied.Results:Despite eliminating the factors suggested as causes of ETV failure in infants below six months; the type, as with the communicating hydrocephalus, the thickness of the third ventricular floor, history of previous intracranial hemorrhage or central nervous system infection, still the success rate did not exceed 12.5%.Conclusions:The complication rate following ETV was low in comparison to the high frequency (20–80%) and seriousness of the possible postoperative complications following VP shunt with a significant decrease in the quality of patients’ lives. Hence the decision-making as well as the parental counselling were in a trial to estimate the ETV success or the need to perform a shunt in the treatment of obstructive hydrocephalus.
Endoscopic third ventriculostomy (ETV) allows the cerebrospinal fluid (CSF) to flow directly from the third ventricle through the fashioned ventriculostoma to the interpeduncular cistern, by passing the site of obstruction. In spite of the wide variety of indications where ETV is implemented, its success rate is still debatable especially in certain age groups, where it is most successful in adult patients with obstructive hydrocephalus and it has an identifiable failure rate in children less than 6 months of age. Several factors would affect the success rate of ETV, which are related to the patient's age, pathology, and intraoperative findings. This chapter covers most of the current debates considering ETV.
Objectives Ventriculoperitoneal (VP) shunting is commonly used to treat pediatric hydrocephalus, but failure rates are high. VP shunt failure in children is mostly caused by infection and/or proximal/distal shunt obstruction. However, to our knowledge, no previous reviews have discussed this topic using only clinical studies when age-related data could be obtained. This systematic review aimed at reevaluating what is already known as the most common causes of shunt failure and to determine the incidence and causes of VP shunt failure during the first 2 years of life as a step to establish solid evidence-based guidelines to avoid VP shunt failure in infants.
Methods We performed a search using the search terms “Cerebrospinal Fluid Shunts” (Medical Subject Headings [MeSH]) AND failure [All Fields] AND (“humans” [MeSH] AND English [lang] AND “infant” [MeSH]). Only articles that specifically discussed VP shunt complications in children < 2 years were included.
Results We found that the most common causes of VP shunt failure in children < 2 years were shunt obstruction and infection, both observed in a range.
Conclusion VP shunt failure is very common in infants, mostly resulting from obstruction and infection. Future studies should focus on methods designed to avoid these complications or on alternative treatments for hydrocephalus.
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.
