High-resolution CT in Long-term Follow-up After Lung Transplantation (Discussion End)

Central bronchial dilatation, the finding that correlated with bronchiolitis obliterans in other studies, was an intermediate finding in our material, usually appearing after reduction of the peripheral bronchovascular markings. A possible mechanism for the development of bronchial dilatation might be increased resistance in peripheral airways caused by obliteration of the small bronchi. In some patients […]

High-resolution CT in Long-term Follow-up After Lung Transplantation (Discussion Beginning)

The value of CT in detecting chronic changes after lung transplantation has been considered controversial.’’’ Although most authors who have investigated HRCT in parenchymal lung diseases regard the method as valuable,’ it has been suggested that bronchiolitis obliterans was not reliably identifiable on HRCT from two lungs that were fixed for pathologic-radiologic correlation. Similarly, Medina […]

High-resolution CT in Long-term Follow-up After Lung Transplantation (Results)

During the mean follow-up period of 26 months (range, 6 to 42 months), eight patients developed BOS. Histologic verification of bronchiolitis obliterans was available in five cases. The average postoperative time interval until the onset of BOS was 11.6±5.0 months (range 6 to 15 months). Another two patients showed a decline in FEY, of more […]

High-resolution CT in Long-term Follow-up After Lung Transplantation (Materials and Methods)

Patients Thirteen consecutive lung transplant recipients who were operated on from 1990 through February 1994 with a follow-up period of at least 6 months (range, 6 to 42 months) were included in this analysis. Single lung transplantation was performed on seven patients, double lung transplantation on five, and heart-lung transplantation on one patient. The indications […]

High-resolution CT in Long-term Follow-up After Lung Transplantation (Introduction)

Objective: Our aim was to evaluate the development of changes on high-resolution CT (HRCT) associated with chronic pulmonary rejection. Materials and Methods: Repeated HRCT examinations were performed 140 times on 13 consecutive lung transplant recipients during a mean observation period of 26 months. The postoperative time interval to the first detection of each chronic change […]
