Pediatric ventriculoperitoneal shunt: a comparative study between anterior fontanel ultrasound-guided versus conventional cranial end insertion

Purpose Ventriculoperitoneal (V-P) shunt is one of the most common neurosurgical procedures in pediatrics for the treat-ment of hydrocephalus. Shunt failure is one of the common mechanical complications which lead to major morbidities. This study aims to compare between cranial part insertions of the V-P shunts guided by trans-anterior fontanel ultrasound versus conventional insertion.Methods A prospective comparative randomized study was conducted on 60 pediatric patients aged <= 2 years who suffered hydrocephalus and allocated into 2 groups. In the first group (n = 30), the cranial parts of the ventriculoperitoneal shunts were inserted guided by trans-anterior fontanel ultrasound, and in the second group (n = 30), the insertions were by the conventional method. The follow-up duration of the patients was 3 months.Results Proximal part obstruction of the V-P shunt was found in 3 cases of the conventional group during follow-up with statistical insignificance (p = 0.237) while adequate proximal part location recorded statistical significance (p = 0.0005) in favor of ultrasound-guided group.Conclusion The use of the anterior fontanel ultrasound guide during ventriculoperitoneal shunt insertion is a feasible, safe, and effective technique for the placement of ventricular catheters in pediatric patients with a patent anterior fontanel.
