Purpose: Breast reconstruction using free-tissue transfer yields improved long-term aesthetic results as reported by patients, but requires increased resources of practitioners and hospital systems. Much of the complexity of microvascular reconstruction can be attributed to flap harvest, as dissection must account for anatomic variability, and is guided at best by ancillary imaging modalities which must be extrapolated to the patient on the table. Augmented reality affords the opportunity to superimpose relevant imaging on a surgeon’s native field of view. This potentially allows integration of imaging in real-time to better guide flap selection and facilitate dissection. We aimed to assess the spatial fidelity of key anatomic landmarks on augmented-reality projections compared to 3D printed anatomic simulacrum models formatted from CT-Angiography (CTA) imaging in patients undergoing autologous breast reconstruction.
