Identifying the intersegmental line using a concave portion during upper lobe apical segmentectomies.

ABSTRACT:

Objectives

The hilum approach of intersegmental division along the intersegmental vein is difficult in the case with central vein type during upper lobe apical segmentectomy. We aimed to explore the possibilities of the simple intersegmental division used the concave portion of the apical pleura with computed tomography images.

Methods

We evaluated computed tomography images of patients who underwent anatomical lung resection between June 2020 and April 2024. The upper pulmonary vein branching pattern was categorized into apical, apico-central and central vein types. We evaluated whether the peripheral points of intersegmental veins (left V1 + 2a or right V1b) could be identified, on which portions (anterior-convex, concave and apical-convex) within the apical pleura in each
