Abstract BACKGROUND Neonatal intraventricular hemorrhage remains a significant source of morbidity in premature and low-weight patients. Approximately 15% of patients who require cerebrospinal fluid shunting develop trapped fourth ventricle (TFV). Surgical treatment presents challenges with short- and long-term complications. OBJECTIVE To describe a technique that applies the Seldinger technique with image-guided endoscopy for direct visualization of catheter placement. METHODS A guidewire is passed down the endoscope while it is positioned in the fourth ventricle. The endoscope is removed while the guidewire is held in place. The catheter is slid down the guidewire. The guidewire is removed and placement is confirmed with image guidance. RESULTS Three patients, all less than 14 mo old, with history of prematurity and intraventricular hemorrhage with ventriculoperitoneal shunts, presented with loculated hydrocephalus with TFV. They each underwent image-guided endoscopic fenestration of the fourth ventricle with placement of a fourth ventricular catheter performed by our described technique. All 3 patients recovered well and were discharged on postoperative day 1. Follow-up imaging showed decompression of the fourth ventricle and good placement of the fourth ventricular catheter. None have had complications from catheter placement, and one revision of a fourth ventricular catheter was needed, which was completed with the same described technique. CONCLUSION This technique is well suited for cases in which a fourth ventricular catheter or a difficult trajectory catheter is needed during endoscopic fenestration or when distorted anatomy is present that would make a straight trajectory with a pen endoscope more difficult or higher risk.

ABSTRACT:Objective:Ventricular catheter placement is a common neurosurgical procedure often resulting in inaccurate intraventricular positioning. We conducted a comparison of the accuracy of endoscopic and conventional ventricular catheter placement in adults.Methods:A retrospective analysis of data was performed on 37 consecutive patients undergoing ventriculo-peritoneal shunt (VPS) insertion with endoscopy and 40 randomly selected, unmatched patients undergoing VPS insertion without endoscopy, for the treatment of hydrocephalus of varied etiology. A grading system for catheter tip position was developed consisting of five intraventricular zones, V1-V5, and three intraparenchymal zones, A, B, C. Zones V1 for the frontal approaches and V1 or V2 for the occipital approaches were the optimal catheter tip locations. Postoperative scans of each patient were used to grade the accuracy of ventricular catheter placement.Results:Seventy-six percent of all endoscopic ventricular catheters were in zone V1 and 100% were within zones V1-V3. No endoscopically inserted catheters were observed in zones V4, V5 or intraparenchymally. Thirty-eight percent of the conventionally placed catheters were in zone V1, 53% in zones V1-3 and 15% intraparenchymally. There was a statistically significant difference in the percentage of catheters in optimal location versus in any other location, favoring endoscopic guidance (p<0.001).Conclusion:We conclude that endoscopic ventricular catheter placement provides improved positioning accuracy than conventional techniques.

The Relationship

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.

Abstract BACKGROUND Freehand ventricular catheter placement may represent limited accuracy for the surgeon's intent to achieve primary optimal catheter position. OBJECTIVE To 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). METHODS In 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. RESULTS The 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. CONCLUSION The 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.
