Evaluation of Evan’s Index by Computed Tomography in Hydrocephalic Children in Tertiary Hospital of Telangana
Journal Title: International Journal of Anatomy Radiology and Surgery - Year 2018, Vol 7, Issue 1
Abstract
ABSTRACT Introduction: Hydrocephalus is one of the important clinical scenario seen in pediatric age group, which, if left untreated can lead to many complications. Mortality caused by hydrocephalus is between 0-3%. Obstruction in the circulation of CSF leads to accumulation of fluid within the ventricular system which causes compression of brain. Ventricular size can be studied by linear or volumetric measurements, out of which linear ratios of the width of the ventricles to the width of skull or brain is the easiest reproducible method; Evan’s index is one such Ventriculographic index. Aim: To evaluate Evan’s Index in hydrocephalic children by Computed Tomography (CT) attending tertiary hospital Telangana. Materials and Methods: CT-scans of 50 normal and 50 hydrocephalic children between 0-12 years attending the Department of Radiology, Niloufer Hospital Hyderabad Telangana, India, between November 2013 to August 2014 were analyzed retrospectively. Maximum frontal horn width and maximum inner diameter of skull were measured and Evan’s index was calculated. The data was analyzed by using Z-test. Results: Out of 50 hydrocephalic cases 24 (48%) were males and 26 (52%) were females, 31 were below 3 years and 19 were above three years. Mean Evan’s index in cases (0.44±0.12) is more than in controls (0.16±0.05) with Z=15.23; p<0.0001. The mean Evan’s index of males (0.45±0.12) was higher than of females (0.43±0.12) which shows no significant results (Z=0.58; p=0.556). The mean Evan’s Index in children below three years (0.47±0.13) was found to be higher than in children above three years (0.38±0.08) where Z=3.03; p=0.002. Conclusion: The mean Evan’s Index was found to be more in males (0.45) than in females (0.43). The mean Evan’s Index was found to be more in hydrocephalic children below three years (0.47) than in above three years (0.38).
