Eligibility
Inclusion criteria
Inclusion criteria: Patients of both sexes; under 18 years old; with a diagnosis of hydrocephalus secondary to a primary central nervous system tumor; located in the posterior fossa, characterized by clinical findings and radiological imaging (CT scan or MRI); Hydrocephalus secondary to a posterior fossa tumor will be characterized when the patient presents a tumor in the posterior fossa, causing obstruction of cerebrospinal fluid circulation; enlargement of the lateral ventricles and third ventricle, with this enlargement documented through imaging exams such as cranial CT or MRI; identification, in addition to the ventricular enlargement, of an increase in the temporal horns of the lateral ventricles (>2mm); and transependymal edema in the frontal and/or occipital horns of the lateral ventricles; Additionally, the patient must present signs and symptoms related to increased intracranial pressure, such as: headache; irritability; vomiting; strabismus and/or paresis of the 6th cranial nerve unilaterally or bilaterally; papilledema; bradycardia; hypertension; and altered level of consciousness (drowsiness, stupor, or coma); Participating centers will be those that offer, both through the public health system and/or the private healthcare system, surgical treatment for patients under 18 years old with posterior fossa tumors; Patients who have initially been treated for hydrocephalus at an external center may also be included, provided that all necessary information for study inclusion is available
Exclusion criteria
Exclusion criteria: Patients over 18 years old; patients with lesions in other sites that do not focus primarily on the posterior fossa; patients who have previously undergone surgical resection of posterior fossa tumors; patients without hydrocephalus associated with a posterior fossa tumor; patients with posterior fossa tumors and hydrocephalus but who will not undergo surgical resection of the lesion (for example, diffuse midline pontine gliomas); or cases considered only for biopsy of the lesion; patients who refuse to participate in the study; and patients whose data regarding hydrocephalus and its characterization cannot be retrieved with the necessary details for the study will be excluded from the study
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome of this study will be the number of re-intervention surgeries for hydrocephalus treatment following the index surgery | — |
Secondary
| Measure | Time frame |
|---|---|
| The mortality rate will be assessed by recording the date of death and its relation to hydrocephalus or tumor progression;The infection rate will be evaluated by the number of patients presenting with surgical site infections or other complications | — |
