Progress in three-dimensional computed tomography reconstruction in anatomic pulmonary segmentectomy.

Area of Science:

• Thoracic Surgery
• Medical Imaging
• Oncology

Background:

• Minimally invasive surgeries like video-assisted thoracoscopic surgery and robot-assisted thoracoscopic surgery are increasingly common.
• Anatomic pulmonary segmentectomy is as effective as lobectomy for early-stage non-small cell lung cancer (NSCLC) < 2.0 cm.
• Segmentectomy demands detailed knowledge of pulmonary anatomy, nodule location, and segmental structures.

Purpose of the Study:

• To review the advancements in three-dimensional computed tomography (3D-CT) reconstruction for anatomic pulmonary segmentectomy.
• To highlight the role of 3D-CT in enhancing surgical precision for lung cancer treatment.

Main Methods:

• Review of current literature on 3D-CT reconstruction techniques in thoracic surgery.
• Analysis of how 3D-CT aids in understanding complex pulmonary vasculature and bronchial anatomy.
• Evaluation of 3D-CT applications in preoperative planning and intraoperative guidance for segmentectomy.

Main Results:

• 3D-CT reconstruction effectively visualizes vascular branching patterns and identifies anatomic variations.
• It accurately determines lesion location and clarifies segmental divisions, crucial for precise surgery.
• 3D-CT facilitates preoperative simulation, individualized surgical planning, and intraoperative navigation.

Conclusions:

• 3D-CT reconstruction is a valuable tool for anatomic pulmonary segmentectomy.
• It enhances the safety and efficacy of minimally invasive lung cancer surgery.
• This technology supports the growing trend towards segmentectomy over lobectomy for early-stage NSCLC.
