The contribution of bronchial and pulmonary arteries to local bronchial circulation was serially examined by color-coded silicone rubber injection in dogs to investigate the process of bronchial healing following bronchoplastic reconstruction. Tissue PO_2 of the anastomotic site was also observed using an intravascular PO_2 sensor. In group I, bronchoplasty was performed with the bronchial arteries preserved. In group II, bronchial arteries were ligated or dissected, and the effects of bronchial wrapping by a silicon film or with a free pleural flap on the anastomosis were studied. Restoration of bronchial circulation following bronchoplastic procedure was studied in terms of recovery in microcirculation and oxygenation at the site of anastomosis. Bronchial wrapping did not improve the healing at the site of bronchial anastomosis. Preserving bronchial arteries was very important for local bronchial circulation after bronchoplasty.
