Hemorrhagic infarction of hilar lymph nodes associated with combined heart-lung transplantation.
The histologic changes in lymph nodes transplanted during combined heart-lung transplantation were examined. We studied at autopsy nine patients who had received a total of 10 heart-lung transplants. Hemorrhagic infarction of hilar nodes was found in eight of the 10 transplanted lungs. Pulmonary parenchymal pathologic changes associated with lymph node infarction included acute rejection (two cases), chronic rejection with bronchiolitis obliterans (two cases), and pneumonia (four cases). In one of the transplants without lymph node infarction there was chronic rejection with bronchiolitis obliterans and in another there was evidence of bronchopneumonia. The hemorrhagic lymph node infarction seen in the recipients of combined heart-lung transplant's may be directly attributable to the interruption of bronchial arteries and veins by the surgical procedure. At present the possible contribution of node infarction to postoperative morbidity or mortality is unknown.
