Postoperative changes in low attenuation volume according to the number of resected subsegments: a retrospective cohort study

Key Points

• An increase in low attenuation volume percentage correlates positively with the number of resected subsegments, indicating lung changes post-surgery.
• Patients with six or more subsegments removed show significant increases in low attenuation volume percentage, which relates to hyperinflation.
• Retrospective cohort analysis assessed the impact of extensive lung resection on lung parenchyma preservation and postoperative changes.
• Findings suggest careful consideration of subsegment resection to preserve normal lung function postoperatively.
