Short-Term Deployment of Self-Expanding Metallic Stents Facilitates Healing of Bronchial Dehiscence

Bronchial dehiscence after lung transplantation is difficult to treat and associated with high mortality. We describe our experience using self-expanding metallic stents to treat post–lung transplant bronchial dehiscence. From January 1995 to June 2004, 189 single and 118 double lung transplants were performed in our institution, totaling 425 at-risk bronchial anastomoses. Seven (1.6%) incidents of life-threatening bronchial dehiscence were treated with self-expanding metallic stents. The interval between transplant and diagnosis of dehiscence was 29.1 ± 18.5 days. All patients presented with respiratory distress, and three required mechanical ventilation. Self-expanding metallic stent placement resulted in complete bronchial healing. All three patients with respiratory failure requiring mechanical ventilation were successfully weaned after stent placement. In two later cases, the stents were electively removed after adequate healing of the dehiscence. Complications included stent migration (one patient) ...
