Early diagnosis of the failure of endoscopic third ventricolostomy Aim of the study: The aim of the study is to determine the risk of ETV failure based on the presence or absence of radiological indications of third chamber deformation (bowing of the third chamber) on preoperative MR brain scans in patients with obstructive hydrocephalus. Additionally evaluating extend of the bowing, patients age, regression of bowing following successful ETV, etiology, degree of prematurity of newborns, persistence and character of clinical symptoms and other factors. Type of the study: Prospective clinical study. The data set and methodology: Data set comprised 157 patients with obstructive hydrocephalus operated on Neurosurgical clinic of University Hospital Ostrava between January 2008 and December 2016. The follow up duration was at least 3 months. From this cohort we were able to determine effect of bowing on ETV outcome in 135 patients. Of these patients, 70 were adults, 27 were children between 7 months and 16 years of age and 38 were infants under 6 months. From 38 infants under 6 months were 22 severe premature newborns, 9 moderately premature newborns and 7 mildly premature newborns. The extend of the bowing was determine in the range 3 - 14 mm. Results: ETV was noted as successful in 84 cases (62%). Statistical...
