Preoperative radiological linear indices and ratios do not predict the likelihood of subsequent shunt malfunction. However, patients who required early shunt revision (< 90 days) tended to have greater reductions in ventricular volumes (as measured by a reduction in FOHR) on postoperative images than those who required late revisions. This finding indicates that a greater reduction in ventricular volume is not actually desirable and that a ventricular volume high enough to reduce ICP should be the goal to achieve better long-term shunt compliance.
