Resection of the tracheal bifurcation through a left thoracotomy.

The surgical management of tumors of the left main bronchus with involvement of the lower trachea is one of the most difficult problems of tracheobronchial surgery. Two cases of adenocystic carcinoma in this location are presented, where resection of the tumor and reconstruction of the airway were performed through a left thoracotomy. In one case reconstruction of the tracheobronchial tree could be accomplished without loss of lung parenchyma; in the second case the left lung had to be removed since the lobar bronchi were infiltrated by the tumor. Such extensive left tracheobronchial resections have so far not been reported in the literature.
