“…Yamada et al reported that the incidence of shunt malfunction was very low when the ventricular catheter tip was placed in ipsilateral frontal horn. 1 Previous data suggest that almost one third of adult patients undergoing CSF shunting will require revision. 12 Optimal catheter placement may help reduce the risk of shunt failure.…”

Introduction:Ventriculoperitoneal shunt placement is one of the most commonly performed neurosurgical procedures and it is a standard surgical procedure for hydrocephalus.Despite advances in shunt catheter materials and the valves used, there remains a high rate of shunt failure. Approximately 30% to 50% of shunt surgeries for hydrocephalus require shunt revision within the first Abstract Object: The objective of this study was to determine the relationship of the location of the ventricular catheter tip and function of the ventriculoperitoneal shunt.Methods: This prospective observational study included 140 patients from a single institution who underwent a ventriculoperitoneal shunt procedure in which a new ventricular catheter was placed between September, 2013 and September 2016. Data abstracted for each patient included age, sex, diagnosis, site and side of ventricular catheter placement. Postoperative CT scan images were reviewed for accuracy of ventricular catheter placement. Patients were followed up over 2 ½ to 4 ½ years.63 patients were available for follow up. We lost communication with rest of the patients. The relationship of the location of the ventricular catheter tip and function of the ventriculoperitoneal shunt was analyzed in 63 patients.Results: There were 140 patients included in the study; accuracy ventricular catheter tip placement were 55 (39.28%) using freehand technique. VP shunt functioned well in 43 (68.25%) of 63 patients. Among the 43 patients with well functioning shunt ,19 were in accurate group ,7 were in suboptimal group and 17 were in inaccurate group.26 patients (41.27%) had good outcome with normal development and normal IQ Conclusions: Mechanical malfunction and infection are the most significant problems associated with shunts for the treatment of hydrocephalus. Above all, a significant proportion of shunt failure was due to obstruction of the ventricular catheter, and accurate placement of the shunt catheter is highly important to reduce the incidence of shunt malfunction.

BACKGROUNDFreehand ventricular catheter placement may represent limited accuracy for the surgeon's intent to achieve primary optimal catheter position.OBJECTIVETo investigate the accuracy of a ventricular catheter guide assisted by a simple mobile health application (mhealth app) in a multicenter, randomized, controlled, simple blinded study (GAVCA study).METHODSIn total, 139 eligible patients were enrolled in 9 centers. Catheter placement was evaluated by 3 different components: number of ventricular cannulation attempts, a grading scale, and the anatomical position of the catheter tip. The primary endpoint was the rate of primary cannulation of grade I catheter position in the ipsilateral ventricle. The secondary endpoints were rate of intraventricular position of the catheter's perforations, early ventricular catheter failure, and complications.RESULTSThe primary endpoint was reached in 70% of the guided group vs 56.5% (freehand group; odds ratio 1.79, 95% confidence interval 0.89-3.61). The primary successful puncture rate was 100% vs 91.3% (P = .012). Catheter perforations were located completely inside the ventricle in 81.4% (guided group) and 65.2% (freehand group; odds ratio 2.34, 95% confidence interval 1.07-5.1). No differences occurred in early ventricular catheter failure, complication rate, duration of surgery, or hospital stay.CONCLUSIONThe guided ventricular catheter application proved to be a safe and simple method. The primary endpoint revealed a nonsignificant improvement of optimal catheter placement among the groups. Long-term follow-up is necessary in order to evaluate differences in catheter survival among shunted patients.
