Complications associated with an implantable vascular access device.

Area of Science:

• Pediatric Surgery
• Vascular Access Devices
• Medical Device Complications

Background:

• Implantable ports are crucial for managing pediatric conditions, with modifications enhancing function and patient experience.
• This study focuses on a specific port system, evaluating its mechanical complication profile in a pediatric population.

Purpose of the Study:

• To review the experience with a specific implantable port system in pediatric patients.
• To identify and characterize unique mechanical complications associated with this port system.

Main Methods:

• Retrospective review of 296 port insertions and 175 removals in pediatric patients (1998-present).
• Assessment of medical records, radiographs, and operative findings for complications.
• Focus on the 6.6F MRI Low-Profile Implanted Port, assembled by the operating surgeon.

Main Results:

• 15 complications (5.1%) occurred in 13 patients, including 11 leaks (3.7%) and 4 catheter dislodgments (1.4%).
• Leaks were primarily due to needle perforation of the port base; dislodgments often occurred at the catheter-port connection, with some leading to embolization.
• Average complication onset was 425 days for leaks and 1075 days for dislodgments.

Conclusions:

• Mechanical port complications are not uncommon (5.1%) in this pediatric device.
• The port's thin base may pose a perforation risk, and complications may relate to device wear over extended use.
• Complications, including embolized catheters, were successfully managed, with new port systems implanted in most cases.
