HoloLens in Breast Reconstruction: What Is the Future?

Area of Science:

• Surgical Innovation
• Medical Imaging
• Reconstructive Surgery

Background:

• Deep inferior epigastric perforator (DIEP) flap is standard for autologous breast reconstruction.
• Accurate identification of abdominal vasculature is crucial for DIEP flap dissection, surgical outcomes, and minimizing morbidity.

Purpose of the Study:

• To describe a novel technique using augmented reality (AR) with HoloLens technology for surgical planning in DIEP flap breast reconstruction.
• To assess the accuracy and usability of AR for identifying epigastric arteries and perforators.

Main Methods:

• Preoperative computed tomography angiography (CTA) was used to visualize abdominal vasculature.
• HoloLens AR technology was employed to superimpose CTA images onto the patient, creating a real-time, in vivo anatomical map.
• The accuracy of AR visualization was evaluated against actual anatomy.

Main Results:

• The HoloLens technology accurately identified epigastric arteries and perforators.
• The AR system provided an intuitive, in vivo appreciation of the underlying anatomy.
• The technology demonstrated ease of use and potential for real-time surgical planning.

Conclusions:

• Augmented reality with HoloLens offers a valuable tool for preoperative planning in DIEP flap breast reconstruction.
• This technology has the potential to enhance the accuracy and efficiency of free-flap surgery.
• Further application of AR in reconstructive surgery is encouraged.
