Segmentectomy of the smallest lung segment (S7) is complex due to its branching variations. This study presents a novel technique for performing S7 segmentectomy, addressing challenges in rare anatomical variants.

Area of Science:

  • Thoracic Surgery
  • Pulmonary Anatomy
  • Surgical Techniques

Background:

  • The medial-basal segment (S7) is the smallest pulmonary segment.
  • S7 exhibits significant anatomical complexities and variable bronchial branching patterns (3 types).
  • Anatomical S7 segmentectomy is challenging, with limited reported thoracoscopic procedures for its variants.

Purpose of the Study:

  • To present a unique surgical technique for anatomical S7 segmentectomy.
  • To address the complexities associated with rare S7 anatomical variants.
  • To provide a novel approach for thoracoscopic S7 segmentectomy.

Main Methods:

  • Description of a novel segmentectomy technique specifically for S7.
  • Focus on managing different branching patterns of the B7 bronchus.
