Key result
Unilateral pulmonary artery occlusion testing achieves ~97% technical success with minimal complications during pneumonectomy evaluation.
Why the study?
The technical feasibility and safety of the unilateral pulmonary artery occlusion test in pre-operative evaluation before pneumonectomy or pleuropneumonectomy for lung or pleural tumours were not established.
Is the unilateral pulmonary artery occlusion test technically feasible and safe prior to pneumonectomy or pleuropneumonectomy for malignancy?
Population
91 patients scheduled for pneumonectomy or pleuropneumonectomy for lung or pleural tumours
Comparison

Design
Observational cohort study

Is the unilateral pulmonary artery occlusion test technically feasible and safe prior to pneumonectomy or pleuropneumonectomy for malignancy?
The unilateral pulmonary artery occlusion test is technically feasible and generally safe for pre-operative evaluation prior to pneumonectomy, though severe complications like balloon migration can occur.
Shimohira et al. (2017) conducted an observational in Lung or pleural tumours (n=91). Unilateral pulmonary artery occlusion (UPAO) test was evaluated on Technical success rate (completion of the UPAO test). The unilateral pulmonary artery occlusion test was technically successful in 97% of patients evaluated for pneumonectomy or pleuropneumonectomy, with a complication rate of 1.1%.
