Main bronchial sleeve resection with pulmonary conservation.

This article aims to present the experience of our clinic regarding 4 cases of primitive bronchial disease for which a main bronchial sleeve resection with pulmonary conservation were performed between 2005 and 2006. The reduced number of cases allows us express the opinion that in well evaluated cases where bronchoscopic exam is essential the main bronchial sleeve resection and full lung preservation is a procedure that can be made with excellent results for the patient. Life quality is superior to that of cases with pneumonectomy which can be a disease by itself.
