Description
The authors image the remaining lung after pneumonectomy in a 2025 study. Removing a whole lung rewrites airflow and blood flow balance. Gravity normally skews the ventilation-perfusion ratio by height. Complications like chest infection further distort the picture.
Thirty patients with post-surgical empyema were scanned. Most were assessed within five years of surgery. Flow shares were measured across upper, middle, and lower fields. The middle field carried nearly half of both measures. Right lungs perfused their lower field more than left lungs did. Ventilation shares tracked perfusion shares closely overall. The ratio sat below one up top and above one below. Gravity's usual pattern was partly inverted after surgery. Sex and time since surgery entered the analysis. The authors chart adaptation of the single lung. Follow-up imaging gains reference values. Surgical outcome assessment can use these distributions.
