    Abstract:
    OBJECTIVES: This study aims to establish the preoperative risk factors in the development of acute respiratory distress syndrome (ARDS) and early mortality after pneumonectomy for lung cancer and to examine the influence of reduced pulmonary perfusion on outcomes. METHODS: Between 1994 and 2009, of 425 patients who underwent simple pneumonectomy for primary lung cancer, 164 who were preoperatively evaluated with lung perfusion scanning formed the population of this study. RESULTS: Of 30 (18.3%) patients who had major pulmonary complications, 17 (10.4%) progressed to ARDS, 15 of whom subsequently died. On multivariable logistic regression analyses, lower predicted postoperative forced expiratory volume in 1 second (ppo-FEV(1); relative risk of 0.93 [P = .020] for ARDS and 0.94 [P = .027] for mortality) and greater perfusion fraction of resected lung (relative risk of 1.10 [P = .003] for ARDS and 1.09 [P = .002] for mortality) were found to be independent factors associated with ARDS and early mortality. With a cut-off value of 35% for perfusion fraction of resected lung, patients with a perfusion fraction of greater than 35% had a greater incidence of ARDS (17.3% vs 3.3%, P = .005) and early mortality (19.8% vs 6.0%, P = .010) than those with a perfusion fraction of 35% or less. CONCLUSIONS: Patients with a low ppo-FEV(1), a high perfusion fraction of resected lung, or both had a higher incidence of ARDS and early mortality after pneumonectomy. Therefore, although the ppo-FEV(1) appears to be within an acceptable limit for pneumonectomy, much attention should be given to patients with a high perfusion fraction of resected lung.
