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.

AbstractLeft aortic arch with right descending aorta is a rare congenital anomaly. We describe the clinical presentation of this unusual anomaly associated with cardiorespiratory compromise from severe aortic obstruction and left main bronchus compression. The anatomical peculiarities, embryological basis, and surgical solutions are presented.

The use of mediastinal surgery for minimally invasive esophagectomy (MIE) has been proposed; however, this method is not performed as radical surgery because it has been thought to be impossible to perform complete upper mediastinal dissection, including the left tracheobronchial lymph nodes (106tbL). We herein describe a new method for performing complete dissection of the upper mediastinum. We developed a method for performing complete mediastinoscopic esophagectomy as radical surgery via the bilateral transcervical and transhiatal approach in 6 Thiel-embalmed human cadavers. The lower and middle mediastinal lymph nodes are dissected via the transhiatal approach. The dorsal side of the left recurrent nerve is dissected up to the aortic arch and left recurrent nerve lymph nodes (106recL) are dissected under pneumomediastinum. Next, the right recurrent nerve lymph nodes (106recR) are dissected. The cartilage of the left main bronchus is dissected and pushed downward, thereby obtaining a good view between the aortic arch and left main bronchus via the transhiatal approach. The 106tbL lymph nodes are dissected until the aortic arch is reached. Simultaneously, the lymph nodes are dissected via a right cervical incision. This method is termed the “cross-over technique.” We herein demonstrated that the upper mediastinal lymph nodes, including the 106tbL nodes, can be dissected using the bilateral transcervical and transhiatal approach under pneumomediastinum and named this method “mediastinoscopic esophagectomy with lymph node dissection” (MELD). MELD is therefore considered to be a useful modality based on our experience with Thiel-embalmed human cadavers.
