Comparison of MLBS in nonshunted, shunted with higher VOP, and shunted with lower VOP patients posthemispheric surgery and at last follow-up. No statistical difference was observed between nonshunted and shunted with higher VOP patients at last follow-up, whereas shunted with lower VOP patients had significantly greater MLBS than nonshunted patients according to analysis of covariance. **P < .01. MLBS, midline brain shift; NS, no significance; OP, opening pressure; VOP, valve opening pressure.
