Acute, life-threatening complications of lung transplantation

Acute, life-threatening complications of lung transplantation are common in all reported series. The clinical courses and images of 70 patients who underwent heart-lung (n = 5), bilateral sequential lung (n = 31), or single-lung (n = 38) transplantation were retrospectively reviewed. Sixty-five acute, life-threatening complications occurred in 26 patients (37%) within 3 months after transplantation. Nine deaths occurred as a result of these complications for a mortality rate due to acute complications of 13%. The deaths were a result of bleeding (n = 4), sepsis (n = 2), severe acute rejection and adult respiratory distress syndrome (n = 1), multiorgan failure (n = 1), and diffuse alveolar damage and respiratory failure (n = 1), a distribution of causes similar to those in other reported series. Specific diagnoses that can be made with imaging include hemothorax, lung torsion, pneumomediastinum, pulmonary embolism, pneumothorax, bronchial anastomotic dehiscence, lung collapse, paralysis of the diaphragm, and sternal dehiscence.
