P < 0.001). This was not accompanied by any abnormalities on chest roentgenography. The histology was consistent, with marked
perivascular lymphocytic infiltration with little alveolar or interstitial changes. During rejection, the increased pulmonary
vascular resistance in the graft was probably the result of perivascular inflammatory cell infiltration, which was seen prior
to changes on chest roentgenography. Changes in the left pulmonary artery flow and histology thus appear to be closely correlated
in the early stages of acute rejection.

Lung transplantation have significantly improved quality of life in patients with end stage respiratory failure, however use of lifelong immunosuppressive therapy and development of bronchiolitis obliterans reflects in a 5-year survival is less the 60%. Ophthalmic complications following lung transplantation are uncommon. Some cases of infectious and malignant ophthalmic complications have been described previously. Here we describe a case of Horner's syndrome following single lung transplantation. 相似文献

Abstract Acute haemodynamic change after single lung transplantation for primary pulmonary hypertension was evaluated using a rat transplantation model. Inbred Fisher 344 rats were administered with 40 mg/kg monocrotaline in order to induce pulmonary hypertension. The rats whose mean pulmonary arterial pressure (PAP) was over 30.0 mmHg received a left lung isograft from a normal donor after right heart catheterization. In the control group, PAP increased after single lung transplantation. On the other hand, in the pulmonary hypertensive group, PAP was significantly decreased 60 min after the transplantation, but 3 and 6 h after the transplantation, the PAP significantly increased again. On the day after the operation, it again decreased significantly. Left-to-right lung blood flow ratio was significantly increased in rats with pulmonary hypertension compared to rats with normal pulmonary pressure on both the 1st and 3rd postoperative days. The oedema of the grafted lung was more severe in the pulmonary hypertensive group than in the control group in the acute phase. In conclusion, single lung transplantation for pulmonary hypertension shifted pulmonary blood perfusion to the grafted lung and this shift made pulmonary oedema of the grafts more severe in the acute phase. These oedematous changes, which were more pronounced in the grafts in the pulmonary hypertensive rats, might have contributed to the transient rise in PAP in those rats after single lung transplanation. 相似文献

The hemodynamic effect and degree of damage in grafts of single lung transplants for pulmonary hypertension were studied in rats with monocrotaline-induced pulmonary hypertension. Inbred male Lewis rats (weight 200–230 g) were divided into two groups. Group 1 (control group,n = 16) underwent isogenic left lung transplantation, while group 2 (n = 15) received an intravenous administration of monocrotaline (80 mg/kg i.v.) and underwent isogenic left single lung transplantation 3 weeks later. Hemodynamic evaluations were performed prior to transplantation, at 1h postoperatively, and on days 3 and 7 after transplantation. Mean pulmonary arterial pressure (mPAP) rapidly declined after transplantation in group 2, from 39.3 ± 8.7 mmHg to 18.5 ±3.0 mmHg 1h after transplantation, and remained stable on day 7 after tranaplantation. No significant difference in the mPAP between the two groups was observed after tranaplantation. The extravascular lung water volume (ELWV: dry/wet ratio) in the right lung of group 2 significantly increased on day 3 (0.86 ± 0.02) (P < 0.01), and subsequently decreased to control levels on day 7 (0.83 ± 0.02). There was no significant difference in the ELWV in the grafted lungs between the two groups (0.84 ± 0.03 vs 0.86 ± 0.04), but there was tendency toward an increase in ELWV in group 2 on days 3 and 7. These data thus demonstrated that a hemodynamic improvement was obtained by single lung transplantation; however the degree of graft damage was remarkable in the pulmonary hypertension group. 相似文献

Idiopathic pulmonary fibrosis (IPF) is a frequent indication for lung transplantation (LTX) with pulmonary hypertension (PH) negatively affecting outcome. The optimal procedure type remains a debated topic. The aim of this study was to evaluate the impact of pretransplant PH in IPF patients. Single LTX (SLTX, n = 46) was the standard procedure type. Double LTX (DLTX, n = 30) was only performed in cases of relevant PH or additional suppurative lung disease. There was no significant difference for pretransplant clinical parameters. Preoperative mean pulmonary arterial pressure was significantly higher in DLTX recipients (22.7 ± 0.8 mmHg vs. 35.9 ± 1.8 mmHg, P < 0.001). After transplantation, 6‐min‐walk distance and BEST‐FEV1 were significantly higher for DLTX patients (6‐MWD: 410 ± 25 m vs. 498 ± 23 m, P = 0.02; BEST‐FEV1: 71.2 ± 3.0 (% pred) vs. 86.2 ± 4.2 (% pred), P = 0.004). Double LTX recipients demonstrated a significantly better 1‐year‐, overall‐ and Bronchiolitis obliterans Syndrome (BOS)‐free survival (P < 0.05). Cox regression analysis confirmed SLTX to be a significant predictor for death and BOS. Single LTX offers acceptable survival rates for IPF patients. Double LTX provides a significant benefit in selected recipients. Our data warrant further trials of SLTX versus DLTX stratifying for potential confounders including PH. 相似文献

We reviewed the impact of the presence of the native diseased contralateral lung on the outcome after single lung transplantation
for emphysema. Twenty consecutive recipients of single lung transplants for emphysema were reviewed for complications related
to the native lung. Five patients (25 %) suffered major complications arising in the native lung and resulting in serious
morbidity and mortality. The timing of onset varied from 1 day to 43 months after transplantation. We conclude that the susceptibility
of the native lung to complications such as those described in this report is an additional fact to be considered in choosing
the ideal transplant procedure for patients with obstructive lung disease.

Bronchiolitis obliterans following lung transplantation: early detection using computed tomographic scanning 总被引:1,自引:0,他引:1
BACKGROUND: Computed tomographic (CT) scanning may enable earlier diagnosis of chronic lung allograft dysfunction than forced expiratory volume in 1 second (FEV1). A study was undertaken to determine intra-observer and inter-observer agreement of composite and air trapping CT scores, to examine the association of FEV1 with the composite and air trapping CT score, and to relate the baseline composite CT score to changes in FEV1 and changes in the composite CT score over 1 year. METHODS: Lung function and baseline CT scans following transplantation and at subsequent annual follow ups were analysed in 38 lung transplant recipients. Scans were randomly scored by two observers for bronchiectasis, mucus plugging, airway wall thickening, consolidation, mosaic pattern, and air trapping, and re-scored after 1 month. CT scores were expressed on a scale of 0-100 and correlated with FEV1 as a percentage of the post-transplant baseline value. RESULTS: The mean (SD) interval between baseline and follow up CT scans was 11.2 (4.7) months. Inter-observer and intra-observer agreement was good for both the composite and air trapping CT scores. There was a significant association between FEV1 and the composite CT score, with each unit of worsening in the baseline composite CT score predicting a 1.55% and 1.37% worsening in FEV1 over the following year (p<0.0001) and a 1.25 and 1.12 unit worsening in the composite CT score (p<0.0001) for observers 1 and 2, respectively. CONCLUSION: These findings indicate a potential role for a composite CT scoring system in the early detection of bronchiolitis obliterans. 相似文献

Open in a separate windowOBJECTIVESDebate continues on whether a bilateral (BLT) or a single lung transplantation (SLT) is preferred for patients with end-stage chronic obstructive pulmonary disease (COPD). The purpose of this study is to examine the interplay between patient age and transplant type on survival outcomes. METHODSWe performed a retrospective study of lung transplants for COPD at our centre from February 2012 to March 2020 (n = 186). Demographics and clinical parameters were compared between patients based on their age (≤65 vs >65 years old) and type of transplant (single vs bilateral). Cox proportional hazards regression was also performed. P-values <0.05 were considered significant.RESULTSOf the 186 patients with COPD who received lung transplants, 71 (38.2%) received BLTs and 115 (61.8%) received SLTs. There was no significant difference in survival outcomes when looking at patients with single versus BLTs (P = 0.870). There was also no difference in survival between the 2 age groups ≤65 versus > 65 years (P = 0.723). The Cox model itself also did not show a statistically significant improvement in survival outcomes (P = 0.126).CONCLUSIONSLung transplant outcomes in patients with end-stage COPD demonstrated non-inferior results in patients with an SLT compared to patients with a BLT. When we compared the age groups, neither transplant type showed superior survival benefits, suggesting there may be some utility in an SLT in younger recipients. 相似文献
