Ventricular volume changes after successful shunting in hydrocephalic infants

Abstract

Abstract Objectives Due to increased number of patients suffering from hydrocephalus (HCP) and lack of data concerning volumetric changes after shunting operations, this study aims to assess the volumetric changes in brain ventricles after successful ventriculoperitoneal (VP) shunt surgery in correlation with clinical improvement. Patient and methods This study included 20 patients; all of them are below the age of 2 years. All the patients had hydrocephalus, were treated surgically with VP shunts, and have clinically improved over the period of study. We measured the volumetric changes radiologically using the fronto-occipital horn ratio (FOHR) over a period of 6 months postoperatively. Results The frontal and occipital horn ratio was calculated in all these patients both pre and postoperatively. There was a significant radiological improvement in the majority of children after the shunt operation. One month postoperatively, the FOHR decreased to about 85% of its preoperative value in average. The FOHR was found to be significantly improving with time over a period of 6 months reaching 63% of its preoperative value. Conclusion Successful treatment of HCP in infants via VPS seems to be of benefit in decreasing the ventricular size gradually to a near normal FOHR with clinical improvement.
