Validation and modification of a predictive model of postresection hydrocephalus in pediatric patients with posterior fossa tumors

Abstract: Object Postresection hydrocephalus is observed in approximately 30% of pediatric patients with posterior fossa tumors. However, which patients will develop postresection hydrocephalus is not known. The Canadian Preoperative Prediction Rule for Hydrocephalus (CPPRH) was developed in an attempt to identify this subset of patients, allowing for the optimization of their care. The authors sought to validate and critically appraise the CPPRH. Show more

“…The percentage of children who undergo tumor resection especially of infratentorially located tumors and who subsequently require cerebrospinal shunt systems ranges from 10 to 35 %. Several authors have designed models of predicting factors for postresection hydrocephalus in children [7,8,10,19,26]. Even though endoscopic third ventriculostomy before tumor resection is a possible alternative for treatment of elevated ICP due to obstructive hydrocephalus and to prevent shunt placement with its further complications (shunt dysfunction and infection, repeat surgeries, x-ray exposure, life-long shunt dependence, etc.…”

“…Наши данные подтверждают существование персистирующей гидроцефалии в раннем послеоперационном периоде после удаления опухолей ЗЧЯ, несмотря на разрешение окклюзии ликворных путей. Однако необходимость имплантации постоянного ликворного шунта после удаления опухоли ЗЧЯ существенно ниже, чем в представленных литературных данных (18-40%) [3][4][5][6][7][8][9], в нашей работе она составила 8,4%. Мы не обнаружили значимой взаимосвязи между возрастом пациента и риском развития персистирующей гидроцефалии.…”

“…Некоторые исследователи предлагают в целях уменьшения количества шунтированных пациентов всегда использовать эндоскопическую тривентрикулостомию (ЭТВС) в качестве профилактической меры до удаления опухоли ЗЧЯ или одномоментно с этой операцией [2,9,[11][12][13][14][15] ным. Мы считаем, что выполнение «профилактической» ЭТВС детям с опухолями ЗЧЯ до удаления опухоли является неоправданным, а если рассматривать причину гидроцефалии как неокклюзионную, то, вероятно, и малоэффективным.…”

“…The management of hydrocephalus with posterior fossa tumors remains controversial. In recent studies, permanent postoperative cerebrospinal fluid (CSF) diversion was required in 30% -38.7% of the patients [4] [5] [6]. However, awareness regarding factors that predict the need for CSF diversion following posterior fossa tumor surgery are essential for the surgeons during counseling, surgical planning, postoperative course and radiological monitoring [7].…”
