Bilateral bronchial anastomosis in double lung and heart-lung transplantations.
|
| Abstract |
During heart-lung or double lung transplantation, the airway anastomosis is usually made at the tracheal level. Healing of this anastomosis is one source of postoperative complications especially after double lung transplantation (DLT). In this series of 10 patients with cystic fibrosis undergoing DLT, the tracheas of donor and recipient were anastomosed with omental wrapping in 2 cases while the two main stem bronchi were joined without omental wrapping in 8. Endoscopy disclosed no sign of ischaemia in the patients with bilateral bronchial anastomoses. Three patients died on day 20, 21 and 35, respectively, after DLT. Two of these patients (one with a tracheal and the other with bronchial anastomoses) showed no complication at the level of the suture line. The third patient (with bronchial suture) suffered dehiscence of both anastomoses which was attributed to a misdosage of corticosteroids. Of the 6 patients alive after bronchial anastomosis, 3 recovered uneventfully and 3 who had required prolonged postoperative mechanical ventilation developed bronchomalacia. Bronchomalacia was treated by laser resection and stenting. Dehiscence did not occur in any of these six cases. This technique was based on the findings of 12 fresh cadaver dissections showing that collaterals between the bronchial arteries and the pulmonary arteries and veins extend up to the origin of the main stem bronchus. Bronchial suture without omental wrap may be used for double lung and heart-lung transplantation instead of tracheal suture.
