Unilateral thoracoscopic view of the left pneumonectomy. In sequence it is possible to appreciate the isolation and division, by means of a mechanical stapler, of the left main pulmonary artery and of the superior and inferior left pulmonary veins. Finally, the stump of the left main bronchus, previously divided, is extracted from the mediastinum

The effects of ventilation-to-perfusion (VA/Qc) maldistribution within the lungs on measured multiple gas rebreathing variables were studied in 14 dogs. The rebreathing method (using He, C18O, and C2H2) allows for measurements of pulmonary capillary blood flow (Qc), diffusing capacity (DLco), lung gas volume, and the combined pulmonary tissue and capillary blood volume (VTPC). VA/Qc imbalance was created by reversibly occluding the right main pulmonary artery or by reversibly obstructing the left main bronchus in eight dogs. Six additional dogs were ventilated with 10 cmH2O positive end-expiratory pressure (PEEP) to create a bimodal distribution of VA/Qc within the lungs. No significant alterations in computed rebreathing variables, except for a small (14%) decrease in DLco, occurred during right main pulmonary artery occlusion, whereas obstruction of the left main bronchus caused parallel decreases (mean of 46%) in all rebreathing variables. Ventilation with 10 cmH2O PEEP for 3 h caused no alterations in VTPC when compared with postmortem determinations of total lung water. Thus marked alterations in distribution of Qc or creation of VA/Qc maldistributions with PEEP caused no significant changes in rebreathing parameters, whereas obstruction of the left main bronchus resulted in decreases in all rebreathing values consistent with the presumed size of the ventilation defect. Thus it appears that rebreathing estimates of VTPC and other rebreathing parameters are accurate in states of moderate VA/Qc maldistribution within the lung.

Left Pneumonectomy

Abstract Bronchoscopic extraction is the most common treatment of foreign body aspiration. However, surgical interventions are required in cases wherein bronchoscopic extraction is difficult, with the most frequent surgical strategy being bronchotomy or lobectomy. Herein, we report a case of foreign body aspiration wherein left pneumonectomy was inevitable because of a molar incarcerated in the left main bronchus. The large diameter of the foreign body and delayed diagnosis that causes granulomatous hyperplasia are considered to be major factors of requiring high invasive surgery.
