BACKGROUND: Following successful lung transplantation, most of the lung perfusion, as well as ventilation, is shifted towards the transplanted lung. We investigated the changes in perfusion during exercise in lung transplant recipients. PATIENTS AND METHODS: Twelve patients were included in the study. Six patients had emphysema and 6 patients had idiopathic pulmonary fibrosis (IPF). Patients underwent two upright lung perfusion scans: the first at rest and the second during a maximal cardiopulmonary exercise test. Lung perfusion was assessed in each lung and regionally. RESULTS: At rest, patients with emphysema had 83.3 +/- 8 % of total perfusion to the transplanted side and 16.7 +/- 8 % to the native lung, while in the IPF patients, it was 68.7 +/- 12 and 32.7 +/- 10 %, respectively ( P = 0.028). At peak exercise, perfusion shifted from the transplanted lung to the native lung ( P = 0.0095) both in emphysema and IPF patients. CONCLUSIONS: Following successful lung transplantation, most of the perfusion is directed towards the transplanted lung. During exercise, there was a small but significant shift towards the native lung. These findings highlighted the important role of the native lung during maximal exercise. 相似文献

The aim of this study was to investigate the effect on lung function of lung biopsy used in the diagnosis of diffuse lung disease carried out by an open procedure or by video-assisted thoracoscopy. One hundred and sixteen patients with diffuse lung disease who attended the Royal Brompton Hospital were studied retrospectively. Thirty five patients underwent open lung biopsy, and 33 video-assisted thoracoscopic biopsy and 48 had their diagnosis made without biopsy. All patients underwent lung function tests before and after surgery, or at an interval of 3-6 months in those who did not undergo biopsy. No significant differences were found in changes in lung function between those who had and had not undergone biopsy, and the proportions of patients whose lung function improved or deteriorated were similar. Lung biopsy by an open procedure or by video-assisted thoracoscopy did not differ in its effects on lung function. The results for older patients, those with severe disease and those with fibrosing alveolitis were the same as for the whole group. Open lung biopsy for the diagnosis of diffuse lung disease does not deleteriously affect lung function whether carried out by an open or a minimally invasive procedure. 相似文献

BACKGROUND: Lung volume reduction surgery (LVRS) is an accepted treatment modality for patients with advanced emphysema. Recently, successful lung transplantation (LTX) has been reported following LVRS. We assess the pulmonary functions in lung transplant recipients after LVRS. METHODS: 8 patients - 5 males and 3 women--aged 53-66 years with advanced emphysema underwent LVRS. Following clinical deterioration and decline of pulmonary function, patients underwent single LTX. Post transplantation follow-up included pulmonary function, 6 minute walk distance (6 MWD) and recording perioperative complications. RESULTS: Median forced expiratory in one second (FEV 1) before and after LVRS were 24 % with 31 % predicted, respectively. All but one showed improvement in lung function and 6 MWD following LVRS. Median maximal 6 MWD before and after LVRS was 222 and 316 meters, respectively. Median time from LVRS to LTX was 46 months (range 10-83). All patients survived and were discharged after LTX. Median FEV1 before and after LTX was 23 % with 57 % predicted, respectively. Median 6MWD before and after LTX was 240 and 462 meters, respectively. NYHA classes improved from 3-4 to 1-2 in 7 surviving patients. At transplantation, bleeding due to pleural adhesions was observed in 4 patients; two required blood transfusions. One patient developed acute respiratory distress syndrome and one had unilateral vocal cord paralysis. At nine-month follow-up, 7 patients are doing remarkably well, while one patient died 6 months after LTX due to bronchiolitis obliterans syndrome (BOS). CONCLUSIONS: LVRS is a therapeutic option in patients with end-stage emphysema. When emphysema deteriorates, LTX can be successfully performed with significant improvement of quality of life without significant additional risk. 相似文献
