Computed tomography is a useful tool in older children, with completely closed anterior fontanels, and it is also very useful in determining the cause of hydrocephalus and assessing the valve effectiveness. The follow\-up included the period between the original ventriculo\-peritoneal valve implantation and the ultimate outpatient follow\-up visit and ranged between 12 months to 2.5 years in the experimental group and up to 4 years in the controls. Children from the experimental group were admitted two days prior to the scheduled surgery to minimize the risk of nosocomial infections. The experimental group patients received a single antibiotic dose prior to surgery. In my observations, it is difficult to analyze and compare the effectiveness of perioperative antibiotic prophylaxis, since it was routinely employed in the experimental group, but irregular in the controls\; besides, both groups were too small to allow for such an analysis. It should be undoubtedly stated here that the complication rate understood as the percentage of valve system infections was high in the controls and it constituted the baseline level prior to the commencement of the present investigations. 81 Pobrano z https\:\/\/portalwiedzy.cm\-uj.krakow.pl \/ Downloaded from Repository of Jagiellonian University Medical Coll"]
