Augmented Reality Microsurgical Planning with a Smartphone (ARM-PS): A dissection route map in your pocket

摘要： SUMMARY INTRODUCTION: Perioperative microsurgical planning increases the likelihood of successful results. Augmented reality is the addition of artificial information allowing the user to perform tasks more efficiently. The aim of our study is to report the use of augmented reality for microsurgical planning with a smartphone (ARM-PS) as a dissection route map. PATIENTS AND METHODS: Augmented reality was used for superficial circumflex iliac artery perforator flap planning. Three-dimensional reconstruction images of the inguinal and lower abdomen vascular anatomy were performed from computed tomography angiography. Three-dimensional images were imported to a smartphone and an augmented reality app was used to superimpose them with the camera. The drawings performed with ARM-PS were correlated with handheld doppler and intraoperative findings. RESULTS: Correlation of ARM-PS drawings with handheld doppler was 100% for superficial inferior epigastric artery, superficial and deep branch of superficial circumflex iliac artery perforator in sixty inguinal areas studied. Intraoperative findings matched perfectly in all thirty cases with ARM-PS drawings for the mentioned vessels and lymph nodes location. Flap harvest time decreased in 20% compared with our traditional timing. CONCLUSIONS: ARM-PS is an easy, non-invasive and accurate method that provides a dissection route map, standardizing flaps harvesting and has a perfect correlation with intraoperative findings. It reduces operating time and may improve operative results, decreasing donor site morbidity.
