Abstract: on the basis of the findings in relation to restoration and recanalization of the bronchial arteries. Restoration of the bronchial artery in the bronchial anastomotic sites was experimentally tested in regard to wrapping with pedicled omentum (Group II) and pedicled pericardium (GroupIII) in comparison with non-wrapping (Group I) on mongrel dogs. The grades of recanalization of the bronchial artery, which had been interrupted by bronchial sleeve resection, were assessed by means of postmortem bronchial angiography and healing process in anastomotic sites were evaluated by bronchoscopic and histologic examinations during a period from the 3rd day to 7th month following sleeve anastomosis between the left main and the lower bronchus on dogs. The results were as follows 1) Regeneration and recanalization of the bronchial artery are achieved on Day 7 after operation by using omentopexy procedure, whereas there are evidenced on Day 14 or later in either non-wrapping or pedicled pericardial covering. 2) Arterial blood supply to the bronchial wall distal to the anastomotic site is observed on Day 3 of the earliest time period following surgery by using omentopexy procedure, showing an arterial connection with the celiac artery, which becomes manifest within at least 3 or 4 days after performing bronchoplasty. 3) There is no difference in development of the bronchial arterial circulation in the bronchus at periphery between the procedures of non covering in bronchial anastomotic site and covering with the pedicled pericardium. The new growing arterial blood flow increased on Day 7 in the both procedures following bronchoplasty. 4) A new growing bronchial artery throughout the bronchial wall is completed on Day 14, demonstrating no differences in time periods between non-covering and wrapping groups.
