3D-CT anatomy for VATS segmentectomy.

Segmentectomy has become a widely adopted surgical procedure, with recent reports describing the use of video-assisted thoracoscopic surgery (VATS) and robotic surgery. A major feature of segmentectomy is that it requires a three-dimensional (3D) understanding of the patient's pulmonary structure and a thorough preoperative analysis of the patient's individual anatomy. Here, we present our method for VATS segmentectomy based on 3D-computed tomography (3D-CT), with a review of the literature. We focus on techniques for 3D-CT reconstruction, analyses of the individual anatomy and anomalies, preoperative simulations of the procedure and surgical margin, and intraoperative navigation with 3D-CT images. We also reference the roles of members of our multi-disciplinary surgical team.
