The pure distal left main bronchial sleeve resection with total lung parenchymal preservation: report of two cases and literature review.

Pure bronchial sleeve resection and reconstruction is a type of rare thoracic surgery, especially for the second carina reconstruction on the left side, needs more exquisite surgical techniques, and patient selection to such surgery often requires rigorous screening. We present two cases of left main bronchial adenoid cystic carcinoma with the second carina reconstruction. The purpose of this paper is to recommend a useful supplement to conventional surgery for some very selected patients.
