Area of Science:

  • Thoracic Surgery
  • Surgical Oncology
  • Medical Imaging

Background:

  • Pulmonary segmentectomy presents greater technical challenges compared to lobectomy.
  • Accurate surgical planning is crucial for achieving adequate margins in lung cancer surgery.

Purpose of the Study:

  • To highlight the utility of three-dimensional computed tomography (3D CT) angiography in pulmonary segmentectomy.
  • To emphasize the importance of understanding vascular anatomy and segmental borders for surgical success.

Main Methods:

  • Utilizing 3D CT angiography for detailed visualization of pulmonary arterial and venous branching.
  • Employing inflation-deflation techniques to create a clear segmental demarcation line.
  • Analyzing intersegmental and intrasegmental veins to facilitate parenchymal dissection.

Main Results:

  • 3D CT angiography aids in understanding complex pulmonary vasculature for surgical planning.
  • Clear visualization of segmental borders improves the accuracy of segmentectomy.
  • Comprehension of venous structures simplifies parenchymal dissection during the procedure.

Conclusions:

  • Three-dimensional computed tomography (3D CT) angiography is a valuable tool for planning pulmonary segmentectomy.
  • Standardized methods for creating segmental demarcation lines enhance the precision of segmentectomy, particularly for small lung cancers.
