STUDY OF TRACHEOBRONCHIAL HEALING AFTER L UNG AND HEART-LUNG TRANSPLANTATIONS BASED ON A SERIES OF 64 ANASTOMOSES

The authors report an analysis concerning the healing of tracheo-bronc hial anastomoses after lung- and heart-lung transplantation. The prese nt study includes 64 anastomoses selected from a total of 80 cases. Si xteen had to be excluded because of early post-operative death; none o f these deaths was related to an air-way complication. Bronchial heali ng was assessed by bronchoscopic follow-up; the appearance of the sutu re-line was classified according to Couraud's grades. The initial refe rence was the examination at 2 weeks, which was compared to subsequent follow-up. At the initial assessment, 42 anastomoses were grade 1, 4 were grade II, and 18 were grade III. The subsequent anatomic result w as satisfactory for 52 sutures (81 %). The complications were malacia in 2 cases, stenoses treated with a stenting device in 4 cases, dehisc ence in 6 cases. The duration of ischemia and postoperative mechanical respiratory support, as well as the proximal or distal site of the an astomosis appeared to be of significant prognostic value.
