Ventricular catheter tack-down screw

Area of Science:

• Neurosurgery
• Biomedical Engineering

Background:

• Ventriculoperitoneal shunts are frequently revised, especially in pediatric patients.
• Catheter dislodgement, particularly in posterior fossa shunts, is a common reason for revision.
• Current practice involves suturing the shunt to the periosteum.

Purpose of the Study:

• To introduce and evaluate a novel technique for securing ventriculoperitoneal shunts.
• To reduce shunt revisions caused by proximal end displacement in pediatric patients.

Main Methods:

• A new method of fastening the shunt reservoir directly to the skull using titanium screws is described.
• This technique aims to provide a more secure attachment compared to traditional methods.

Main Results:

• The described technique offers a potentially more secure fixation of the shunt reservoir.
• This enhanced security may lead to a reduction in shunt revisions related to proximal end displacement.

Conclusions:

• The novel technique of using titanium screws for direct skull fixation of ventriculoperitoneal shunts shows promise.
• This method has the potential to decrease the rate of shunt revisions in pediatric neurosurgery.
