Abstract

Objective: To determine whether pulmonary function decreases as a function of severity of pectus excavatum, and whether reduced function is restrictive or obstructive in nature in a large multicenter study. Study design: We evaluated preoperative spirometry data in 310 patients and lung volumes in 218 patients aged 6 to 21 years at 11 North American centers. We modeled the impact of the severity of deformity (based on the Haller index) on pulmonary function. Results: The percentages of patients with abnormal forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), forced expiratory flow from 25% exhalation to 75% exhalation, and total lung capacity findings increased with increasing Haller index score. Less than 2% of patients demonstrated an obstructive pattern (FEV1/FVC <67%), and 14.5% demonstrated a restrictive pattern (FVC and FEV1 <80% predicted; FEV1/FVC >80%). Patients with a Haller index of 7 are >4 times more likely to have an FVC of ≤80% than those with a Haller index of 4, and are also 4 times more likely to exhibit a restrictive pulmonary pattern. Conclusions: Among patients presenting for surgical repair of pectus excavatum, those with more severe deformities have a much higher likelihood of decreased pulmonary function with a restrictive pulmonary pattern.
