During a deep inferior epigastric perforator (DIEP) flap harvest, the identification and localization of the epigastric arteries and its perforators are crucial. Holographic augmented reality is an innovative technique that can be used to visualize this patient-specific anatomy extracted from a computed tomographic scan directly on the patient. This study describes an innovative workflow to achieve this.
A software application for the Microsoft HoloLens was developed to visualize the anatomy as a hologram. By using abdominal nevi as natural landmarks, the anatomy hologram is registered to the patient. To ensure that the anatomy hologram remains correctly positioned when the patient or the user moves, real-time patient tracking is obtained with a quick response marker attached to the patient.
Holographic augmented reality can be used to visualize the epigastric arteries and its perforators in preparation for a deep inferior epigastric perforator flap harvest.
Potentially, this workflow can be used visualize the vessels intraoperatively. Furthermore, this workflow is intuitive to use and could be applied for other flaps or other types of surgery.
在腹壁下动脉穿支皮瓣（DIEP）游离过程中，识别和定位腹壁下动脉及其穿支至关重要。全息增强现实技术是一种创新技术，可用于直接在患者身上可视化从 CT 扫描中提取的特定于患者的解剖结构。本研究描述了实现这一目标的创新工作流程。
开发了一个适用于 Microsoft HoloLens 的软件应用程序，将解剖结构可视化作为全息图。通过使用腹部痣作为天然标志，将解剖全息图注册到患者身上。为了确保当患者或用户移动时，解剖全息图保持正确的位置，使用附在患者身上的快速响应标记来获取实时患者跟踪。
全息增强现实技术可用于在准备腹壁下动脉穿支皮瓣游离时可视化腹壁下动脉及其穿支。
该工作流程有可能用于术中可视化血管。此外，该工作流程易于使用，可应用于其他皮瓣或其他类型的手术。
