Course: Open Source–Based 3-Dimensional Liver Modeling Serving Accessibility of Liver Surgery Virtual Planning

CME Credits: 1.00

Released: 2023-06-21

An increasing number of hepatic surgeons have incorporated 3-dimensional (3-D) liver modeling into their preoperative planning. In fact, the virtual modeling alleviates the cognitive load of transforming 2-dimensional (2-D) images into a spatial representation that includes the site of the lesion and the relation to the real vascular anatomy of the patient. In minimally invasive surgery, this spatial identification is critical, since direct palpation is impossible and intraoperative ultrasound is challenging. A reliable preoperative anatomical model allows the surgeon to focus on anticipating technical difficulties, evaluate potential scenarios, and calculate the volume of liver parenchyma. The intuitive handling of these models makes it possible to synchronize the mental models of the surgeons, anesthesiologists, and operating room nurses, and to prepare for collaboration in the operating room.
