Summary

Thoracic surgeons can now visualize individual pulmonary artery and vein branching patterns preoperatively using free software. This 3D imaging tool aids in planning minimally invasive surgeries, reducing risks associated with lung hilum dissections.

Area of Science:

  • Thoracic surgery
  • Medical imaging
  • 3D reconstruction

Context:

  • Pulmonary artery and vein branching patterns in the lung hilum are complex and difficult to discern preoperatively.
  • Current methods lack detailed anatomical visualization, increasing surgical risks.
  • Video-assisted thoracoscopic surgery (VATS) necessitates precise understanding of hilar structures for minimally invasive approaches.

Purpose:

  • To develop and evaluate free application software for creating 3D models of pulmonary vasculature and bronchi from CT images.
  • To provide thoracic surgeons with a tool for preoperative planning and simulation of surgical procedures.
  • To enhance the understanding of individual anatomical variations in the lung hilum.

Summary:

  • Free software allows marking of pulmonary arteries, veins, bronchi, and tumors on sequential computed tomography (CT) images.

  • 3D images are generated within an hour from DICOM-formatted CT slices using readily available software (Metasequoia LE).
  • The software enables 3D simulation of vessel cutting and manipulation, offering a platform for surgical practice.

    • Impact:

    • Reduces the invasiveness of thoracic surgeries by enabling better preoperative planning.
    • Minimizes risks associated with exposing pulmonary vessels in the lung hilum.
    • Offers a valuable, cost-free training tool for surgical residents to simulate operations and improve anatomical understanding.
