Abstract
Anastomotic dehiscence is one of the most serious complications following lung transplantation characterized by necrosis leading to full-thickness anastomotic separation of the bronchial wall. While some of the major risk factors associated with anastomotic dehiscence include surgical technique, perioperative steroids, acute rejection, infection, inadequate organ preservation, and immunosuppression, the primary cause is thought to be anastomotic ischemia. The severity of anastomotic dehiscence determines if bronchoscopic treatments will be successful. The use of self-expanding metallic stents (SEMS) is the cornerstone of the bronchoscopic treatment of severe anastomotic dehiscence without complete anastomotic breakdown. Various surgical techniques have been developed and refined to reduce the incidence of anastomotic dehiscence and airway complications. Regardless of classification schemes, most cases of anastomotic dehiscence are incomplete. There are no published guidelines on absolute indicators for failure of conservative management as an indication for operative intervention for anastomotic dehiscence. Airway reanastomosis in these circumstances is challenging due to the re-operative nature of the field, the poor tissue quality, relative ischemia, and, in many cases, the presence of infection. Allograft pneumonectomy remains an option of last resort with the possibility of re-transplantation depending upon patient status and organ availability.
