Area of Science:

  • Plastic Surgery
  • Biomedical Engineering
  • Medical Devices

Background:

  • Two-stage breast reconstruction commonly uses temporary tissue expanders (TEs) requiring serial saline infusions.
  • Subcutaneous ports for TEs are traditionally located using magnets, which are limited by distance and tissue thickness.
  • Inaccurate port localization can lead to complications during infusions.

Purpose of the Study:

  • To develop and evaluate a novel electronic device, the PortFindr, for precise localization of subcutaneous tissue expander ports.
  • To improve the accuracy and confidence in identifying the center of TE ports compared to traditional methods.
  • To reduce the incidence of complications associated with TE port access during breast reconstruction.

Main Methods:

  • Development of a prototype handheld electronic device (PortFindr) designed for accurate port localization.
  • Evaluation of the PortFindr's performance in locating subcutaneous ports for temporary tissue expanders.
  • Comparison of the device's precision and accuracy against historical magnetic localization methods.

Main Results:

  • The PortFindr prototype demonstrated more accurate and precise localization of subcutaneous ports.
  • The electronic device offers a potential improvement over traditional magnetic methods for port identification.
  • Enhanced localization may lead to fewer inadvertent punctures of tissue expanders.

Conclusions:

  • The PortFindr represents a significant advancement in locating tissue expander ports for breast reconstruction.
  • This device has the potential to minimize complications during saline infusions, improving patient outcomes.
  • Further clinical validation is warranted to establish the PortFindr's efficacy in routine practice.
