Abstract: The restoration of the bronchial artery after bronchoplasty combined with pulmonary angioplasty was studied in relation to the degree of stenosis of the pulmonary artery by means of the microangiographic technique. Thirty-three dogs were used in this study. They were divided into Group A (15 dogs) with sleeve lobectomy alone, Group B (10 dogs) with sleeve lobectomy and a 50% stenosis of the left main pulmonary artery and Group C (8 dogs) with sleeve lobectomy and a 75% stenosis of the left main pulmonary artery. The restoration of the bronchial artery was assessed by microangiography. 1) The restoration of th bronchial artery after bronchoplasty was completed on day 14. The trend toward a ready regeneration of the bronchial artery becomes apparent if some degree of stenosis of the pulmonary artery exists after a duration of seven days. 2) The interrupted bronchial artery starts to restore at the adventitial face and extends throughout the whole wall of the bronchus after the 7th day. 3) From these results, an operative procedure of sleeve lobectomy with pulmonary angioplasty is applicable even though stenosis of the pulmonary artery remains to some degree.
