Area of Science:

  • Thoracic Surgery
  • Pulmonary Medicine
  • Surgical Anatomy

Background:

  • Accurate identification of pulmonary vein branches is crucial for safe and effective S9+10 segmentectomy.
  • Deeply located common basal pulmonary vein branches pose a challenge in lung parenchyma exposure.

Purpose of the Study:

  • To evaluate the utility of the intersegmental tunnelling method for precise identification of S9+10 segment pulmonary veins.
  • To assess the feasibility of applying this technique in thoracoscopic S9+10 segmentectomy.

Main Methods:

  • Application of the intersegmental tunnelling method during thoracoscopic S9+10 segmentectomy.
  • Surgical procedure performed on five patients between April 2014 and December 2015.

Main Results:

  • The intersegmental tunnelling technique facilitated accurate recognition of dominant pulmonary vein branches supplying the S9+10 segment.
  • Successful execution of thoracoscopic S9+10 segmentectomy using the described method.

Conclusions:

  • The intersegmental tunnelling method is effective for precise identification of pulmonary veins during S9+10 segmentectomy.
  • This technique enables accurate performance of lateral and posterior basal segmentectomies.
