- Abstract
Objectives: Minimally invasive lung transplantation (MILT) via bilateral anterior thoracotomies has emerged as a novel surgical strategy with potential patient benefits when compared with transverse thoracosternotomy (clamshell incision, CS). The aim of this study is to compare MILT with CS by focusing on operative characteristics, postoperative organ function and support and mid-term clinical outcomes at Harefield Hospital., Methods: It was a retrospective observational study evaluating all bilateral sequential lung transplants between April 2010 and November 2013., Results: CS was performed in 124 patients and MILT in 70 patients. Skin-to-skin surgical time was less in the MILT group [285 (265, 339) min] compared with CS [380 (306, 565) min] and MILT-cardiopulmonary bypass [426 (360, 478) min]. Ischaemic time was significantly longer (502 ± 116 vs 395 ± 145 min) in the MILT group compared with CS (P < 0.01). Early postoperative physiological variables were similar between groups. Patients in the MILT group required less blood [2 (0, 4) vs 3 (1, 5) units, P = 0.16] and platelet transfusion [0 (0, 1) vs 1 (0, 2) units, P < 0.01]. The median duration of mechanical ventilation was shorter (26 vs 44 h, P < 0.01) and intensive therapy unit stay was 2 days shorter (5 vs 7) in the MILT group. While overall survival was similar, fraction of expired volume in 1 s (FEV1) and forced vital capacity (FVC) were consistently higher in the MILT group compared with CS during mid-term follow-up after transplantation. Specifically, FEV1 and FVC were, respectively, 86 ± 21 and 88 ± 18% predicted in the MILT group compared with 74 ± 21 and 74 ± 19% predicted in the CS group (P < 0.01) at the 6-month follow-up., Conclusions: MILT was successfully introduced at our centre as a novel operative strategy. Despite longer ischaemic times and a more complex operation and management, MILT appears to offer early postoperative and mid-term clinical benefits compared with our traditional approach of clamshell operations. These observations warrant larger definite studies to further evaluate the impact of MILT on physiological, clinical and patient-reported outcomes., (© The Author 2016.

- Abstract
Background: Limited data are available about lung transplantation (LTx) from donors suffering cardiac arrest (CA) prior to actual donation., Methods: A retrospective analysis of LTx performed between January 2007 and September 2012 was done with the focus on CA in donors. The recipients were grouped depending on the history of donor CA and CA duration (downtime) as: No cardiac arrest ("NoCA"), CA downtime less than 20 min ("CA < 20"), and CA downtime equal to or more than 20 min ("CA > 20"). Early and mid-term outcomes after LTx were compared among the three groups., Results: A total of 237 LTx were performed during the study period. One hundred eighty-eight patients received organs from "NoCA" donors, 25 from "CA < 20" donors, and 24 patients from "CA > 20" donors. There was a trend toward better overall cumulative survival in both CA groups (log rank p = 0.076) whereas the survival in the "CA > 20" group was significantly better than in the "NoCA" group in the subgroup analysis (log rank p = 0.045). Freedom from bronchiolitis obliterans syndrome (BOS) also increased with increase in CA duration, although it did not reach statistical significance., Conclusions: Transplantation of lungs from donors with a history of CA is safe and feasible. Longer duration of cardiac arrest may improve the outcomes after the LTx in terms of survival and freedom from BOS., (© 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

- Abstract
Background: The risk-benefit for utilizing cardio-pulmonary bypass (CPB) in lung transplantation (LTx) remains debatable. This study compares outcomes after LTx utilizing different CPB strategies - elective CPB vs. off-pump vs. off-pump with unplanned conversion to CPB., Methods: A total of 302 LTx performed over seven yr were divided into three groups: "off-pump" group (n = 86), "elective on-pump" group (n = 162), and "conversion" group (n = 54). The preoperative donor and recipient demographics and baseline characteristics and the postoperative outcomes were analyzed; 1:1 propensity score matching was used to identify patients operated upon using elective CPB who had risk profiles similar to those operated upon off-pump (propensity-matching 1) as well as those emergently converted from off-pump to CPB (propensity-matching 2)., Results: Preoperative group demographic characteristics were comparable; however, the "off-pump" patient group was significantly older. The "conversion" group had a significantly greater number of patients with primary pulmonary hypertension, pulmonary fibrosis, preoperative mechanical ventilation, and preoperative extracorporeal life support (ECLS). Postoperatively, patients from the "conversion" group had significantly poorer PaO2 /FiO2 ratios upon arrival in intensive care unit (ICU) and at 24, 48, and 72 h postoperatively, and they required more prolonged ventilation, longer ICU admission, and they experienced an increased need for ECLS than the other groups. Overall, cumulative survival at one, two, and three yr was significantly worse in patients from the "conversion" group compared to the "off-pump" and "elective on-pump" groups - 61.9% vs. 94.4% vs. 86.9%, 54.4% vs. 90.6% vs. 79.5% and 39.8% vs. 78.1% vs. 74.3%, respectively (p < 0.001). The "off-pump" group had significantly better PaO2 /FiO2 ratios, and a significantly shorter duration of ventilation, ICU stay, and hospital length of stay when compared to the propensity-matched "elective on-pump" group. There were no statistically significant differences in postoperative outcomes and overall survival between the "converted" group and the propensity-matched "elective on-pump" group., Conclusions: Despite segregation of unplanned CPB conversion cases from elective on-pump cases, patients with comparable preoperative demographic/risk profiles demonstrated better early postoperative outcomes and, possibly, an improved early survival with an off-pump strategy. A considerable proportion of high-risk patients require intraoperative conversion from off-pump to CPB, and this seems associated with suboptimal outcomes; however, there is no significant benefit to employing an elective on-pump strategy over emergent conversion in the high-risk group., (© 2015 John Wiley & Sons A/S.

- Abstract
Objectives: Due to organ shortage in lung transplantation (LTx), donation after circulatory death (DCD) has been implemented in several countries, contributing to an increasing number of organs transplanted. We sought to assess long-term outcomes after LTx with organs procured following circulatory death in comparison with those obtained from donors after brain death (DBD)., Methods: Between January 2007 and November 2013, 302 LTxs were performed in our institution, whereby 60 (19.9%) organs were retrieved from DCD donors. We performed propensity score matching (DCD:DBD = 1:2) based on preoperative donor and recipient factors that were significantly different in univariate analysis., Results: After propensity matching, there were no statistically significant differences between the groups in terms of demographics and preoperative donor and recipient characteristics. There were no significant differences regarding intraoperative variables and total ischaemic time. Patients from the DCD group had significantly higher incidence of primary graft dysfunction grade 3 at the end of the procedure (P = 0.014), and significantly lower pO2/FiO2 ratio during the first 24 h after the procedure (P = 0.018). There was a trend towards higher incidence of the need for postoperative extracorporeal life support in the DCD group. Other postoperative characteristics were comparable. While the overall cumulative survival was not significantly different, the DCD group had significantly poorer results in terms of bronchiolitis obliterans syndrome (BOS)-free survival in the long-term follow-up., Conclusions: Long-term results after LTx with organs procured following DCD are in general comparable with those obtained after DBD LTx. However, patients transplanted using organs from DCD donors have a predisposition for development of BOS in the longer follow-up., (© The Author 2015.

- Abstract
Background: Traditionally, patients on extracorporeal membrane oxygenation (ECMO) are sedated and mechanically ventilated, which increases risk of complications related to immobility and mechanical ventilation. The purpose of this study was to assess the feasibility and highlight the benefits of a bridge to lung transplant (LTx) using "awake ECMO" support., Methods: The peripheral venovenous or venoarterial ECMO was implanted at a bedside. A retrospective study of patients undergoing LTx between January 2007 and March 2013 was performed. Outcomes in patients supported on ECMO as a bridge to LTx and kept "awake" (Group 1) were compared with the rest of the LTx patients (Group 2)., Results: In this period, 249 LTx were performed and in them 7 patients were bridged to LTx using "awake ECMO" strategy. Two patients were awake at ECMO implantation and throughout the therapy, and two patients were on ventilator support at the time of ECMO implantation who were extubated later and maintained awake until LTx. The remaining three patients were awake for some time during the ECMO. There was no statistically significant difference in most donor characteristics and recipient baseline characteristics as well as post-LTx parameters between the two groups. One-year survival estimate was not different between the groups: Group 1, 85.7% vs. Group 2, 86.3% (log rank p = 0.99)., Conclusion: In end-stage lung disease, the ECMO can be commenced in "awake" patients and patients can be awakened on ECMO. The "awake ECMO" strategy may avoid complications related to mechanical ventilation, sedation, and immobilization and provide comparable outcomes in the high-risk LTx patients., (Georg Thieme Verlag KG Stuttgart · New York.)

- Abstract
Objectives: Lung transplantation (LTx) is a life-saving therapy for patients with end-stage lung disease. However, there remains a significant postoperative complication rate and mortality in this extreme patient group. The aim of the present study was to identify donor, recipient and perioperative risk factors for one-year mortality after LTx., Methods: A total of 252 LTxs were performed in our institution between 2007 and 2013. Donor and recipient demographics and clinical characteristics of 1-year survivors and non-survivors were collected and compared retrospectively. Multivariate logistic regression analysis was performed on univariate predictors for 1-year mortality with an entry criterion of P < 0.05., Results: Multivariate analysis revealed female-to-male transplantation (95% CI: 0.088-0.767; P = 0.015), lower pO2/FiO2-ratio at 72 h postoperatively (95% CI: 0.988-0.999; P = 0.024), need for postoperative extracorporeal membrane oxygenation (ECMO) support (95% CI: 0.035-0.658; P = 0.012) and on-pump technique (95% CI: 0.007-0.944; P = 0.045) as the only independent predictors for 1-year mortality. Mainly unplanned intraoperative conversion to cardiopulmonary bypass contributed to poorer survival in patients who underwent LTx using cardiopulmonary bypass (P < 0.001)., Conclusions: Our results show that the unplanned use of CPB (conversion from off- to on-pump) might adversely affect outcome after LTx. Also, the negative impact of female-to-male transplantation should not be underestimated during recipient selection. Furthermore, poor early postoperative oxygenation, particularly with the need for extracorporeal oxygenation, might be a very strong negative prognostic factor after LTx., (© The Author 2014.

- Abstract
Lung transplantation (LTx) from "extended donor criteria" donors may reduce significantly organ shortage. However, its influence on results remains unclear. In this study, we evaluate retrospectively the results of LTx from donors outside standard criteria: PaO2/FiO2 ratio < 300 mmHg, age over 55 years, and history of smoking > 20 pack-years. Two hundred and forty-eight patients underwent first time LTx in our institution between January 2007 and January 2013. Seventy-nine patients (Group I) received organs from "extended donor criteria" and 169 patients (Group II) from "standard donor criteria." Recipients' and donors' demographics, perioperative variables, and outcome were compared. Donors from Group I were significantly older [median (interquartile range)]: 52.5 (44;58) vs. 42 (28.5;48.5) years (P < 0.001) with lower PaO2/FiO2 ratio: 366 ± 116.1 455 ± 80.5 mmHg (P < 0.001), higher incidence of smoking history: 57.7% vs. 41.8% (P = 0.013), and more extensive smoking history: 24(15;30) vs. 10(3.75;14) pack-years (P < 0.001). Other parameters were comparable. Recipients' gender, diagnosis, percentage of patients operated on pump and receiving double LTx were also comparable. Recipients from Group I were significantly older: 50 (42;57) vs. 44 (29.5;53.5) years (P = 001). There were no differences observed in recipients' prevalence of primary graft dysfunction (PGD) grade 3 over first three postoperative days, duration of mechanical ventilation, intensive care and hospital length of stay, prevalence of rejection, and bronchiolitis obliterans syndrome (BOS). 90-day, 1-year, and 5-year survival (Group I vs. II) were also similar: 88.6% vs. 91.7%, 83.2% vs. 84.6%, and 59% vs. 68.2% (log rank P = 0.367). Carefully selected donor lungs from outside the standard acceptability criteria may expand existing donor pool with no detrimental effect on LTx outcome., (© 2014 Steunstichting ESOT.)

- Abstract
Background: Lung transplantation (LTx) is a complex surgical procedure conventionally performed with clamps on the recipient pulmonary artery (PA) and left atrial (LA) cuff, with or without cardiopulmonary bypass (CPB). The clamps may be awkward to apply and maintain on these structures, potentially causing injury and possibly compromising the quality of anastomosis. We describe a no-clamp technique for performing these types of anastomoses., Methods: A total of 184 LTx procedures performed under CPB were grouped depending on clamping of recipient PA and LA during anastomosis using either the "no-clamp" technique (Group 1, n = 41) or the conventional technique (Group 2, n = 143). Pre-operative donor and recipient demographics and baseline characteristics as well as post-operative outcomes were compared., Results: The demographics and pre-operative baseline characteristics of donors and recipients in both the groups were similar. Patients in Group 1 had a significantly shorter total ischemic time (p < 0.001), CPB time (p < 0.001), decreased incidence of post-LTx atrial fibrillation (p = 0.048), less need for blood and blood products transfusion, and fewer post-LTx pulmonary infections (p = 0.038). No patient in any group had post-LTx stroke. Although the incidence of post-operative bronchiolitis obliterans syndrome (BOS) did not differ between the two groups (p = 0.638), patients in Group 1 had significantly better mid- and long-term survival (p = 0.013): 89.7% vs 80%, 89.7% vs 66.5% and 89.7% vs 62.2% at 1, 3 and 6 years after LTx, respectively., Conclusions: The no-clamp technique for anastomosis of PA and LA in LTx is feasible and safe. It may reduce warm ischemia time as well as CPB time, with improvement in post-LTx outcomes. It may also reduce the incidence of post-LTx atrial arrhythmias., (Copyright © 2014 International Society for Heart and Lung Transplantation. Published by Elsevier Inc. All rights reserved.)

- Abstract
Background: Lung transplantation (LTx) is significantly limited by donor organ shortage. Donor smoking history of more than 20 pack-years is considered an extended donor criterion. In this study, we retrospectively evaluated impact of donor smoking history and extent of smoking on midterm outcome after LTx., Methods: In all, 237 LTx were performed in our institution between 2007 and 2012. Patients were divided into three groups, receiving lungs from 53% nonsmoking donors, 29% smoking donors with fewer than 20 pack-years, and 18% heavy smokers with more than 20 pack-years., Results: Preoperative donor and recipient characteristics among the groups were comparable. However, donors from the heavy smokers group were significantly older (p < 0.001). The overall presence of abnormal histology (inflammation or metaplasia) in donor main bronchi samples increased with the extent of smoking but did not reach statistical significance (p = 0.211). Although metaplasia was found in significantly more donors from the heavy smokers group (p = 0.037), this did not translate into inferior outcomes for the recipients. There were no statistically significant differences in PaO2/FiO2 ratio after LTx, duration of mechanical ventilation (p = 0.136), intensive care unit stay (p = 0.133), and total postoperative hospital stay (p = 0.322). One-year and three-year survival were comparable across all three groups (log rank p = 0.151). Prevalence of bronchiolitis obliterans syndrome (p = 0.616), as well as bronchiolitis obliterans syndrome free survival (p = 0.898) after LTx were also comparable., Conclusions: In our experience, history and extent of donor smoking do not significantly affect early and midterm outcomes after LTx. Although this finding does not obviate the need for longer-term observation, donor lungs from even heavy smokers may not per se contraindicate LTx and may provide a valuable avenue for expanding donor organ availability., (Copyright © 2014 The Society of Thoracic Surgeons.

Age-related native pathologic conditions are an inevitable sequela in long-term survivors of solid organ transplantation. A sexagenarian presented with severe aortic valve stenosis 10 years after lung transplantation (LTx). Despite overwhelming concerns of infection because of long-term immunosuppression and the risk of postoperative deterioration of function in transplanted lungs, an open heart surgical procedure with appropriate perioperative management was undertaken, and a successful aortic valve replacement (AVR) was performed., (Copyright © 2014 The Society of Thoracic Surgeons.

- Abstract
Objectives: Donor organ shortage remains to be the major limitation in lung transplantation, and donation after circulatory death (DCD) might represent one way to alleviate this problem. DCD was introduced to our institution in 2007 and has been a part of our clinical routine since then. Here, we present the mid-term results of lung transplantation from DCD in a single institution and compare the outcomes with the lung recipient cohort receiving lungs from donation after brain death (DBD)., Methods: Since initiation of the DCD programme in March 2007, of the 157 lung transplantations performed, 26 (16.5%) were retrieved from DCD donors, with 25 double- and 1 single-lung transplants being performed. Results were compared with standard DBD transplantations. Analyses included, amongst others, donor characteristics, survival, prevalence of primary graft dysfunction, acute rejection, lung function tests during follow-up, onset of bronchiolitis obliterans syndrome (BOS) as well as duration of mechanical ventilation, hospital and intensive care unit length of stay., Results: While there was no significant difference between lung function, BOS and survival between the two groups, lungs from DCD donors had a higher PaO(2) (median; interquartile range) 498.3 (451.5; 525) vs. DBD 442.5 (371.25; 502) kPa before retrieval (P = 0.009). There was also a longer total ischaemic time in the DCD vs. DBD group: 320 min (298.75; 393.25) vs. 285.5 min (240; 373) (P = 0.025). All other parameters were comparable., Conclusions: Medium-term results after lung transplantation with organs procured after circulatory death are comparable with those obtained after standard lung transplantation. Therefore, DCD could be used to significantly increase the donor pool.

- Abstract
Background: Ex vivo lung perfusion (EVLP) is a novel approach for extended evaluation and/or reconditioning of donor lungs not meeting standard International Society for Heart and Lung Transplantation criteria for transplantation., Methods: We retrospectively evaluated 13 consecutive EVLP runs between January 2009 and December 2010. Lungs rejected for routine transplantation were implanted to the EVLP circuit and reperfused using acellular supplemented Steen Solution (Vitrolife, Göteborg, Sweden) up to a target flow rate of 40% of the donor's calculated flow at a cardiac index of 3.0 liters/min/m(2); target left atrial pressure < 5 mm Hg; and pulmonary artery pressure < 15 mm Hg. Mechanical ventilation was introduced after rewarming to 32°C: tidal volume, 6 to 8 ml/kg; respiratory rate, 7 to 8 breaths/min; duration of inspiration/expiration (I/E) ratio, 1:2; and positive end-expiratory pressure, 5 to 10 cm H(2)O. Hemodynamic and respiratory data monitoring with hourly clinical assessment were performed. Donor data, conversion rate to transplantation, and recipient outcome were analyzed., Results: Donor data (n = 13) were: age, 44.23 ± 8.33 years; female/male, 8:5; cause of death: intracranial hemorrhage, 11 (85%), stroke, 1 (7.5%), hypoxic brain injury, 1 (7.5%); smoking history, 9 (69%), 17.44 ± 8.92 pack-years; mechanical ventilation, 102.6 ± 91.92 hours; chest x-ray imaging: abnormal, 12 (92.5%); normal, 1 (7.5%). EVLP: mean 141 ± 28.83 minutes. Arterial partial pressure of oxygen/fraction of inspired oxygen 100% before termination of the circuit vs pre-retrieval value: 57.32 ± 9.1 vs 42.36 ± 14.13 kPa (p < 0.05). Six (46%) pairs of donor lungs were transplanted. Median follow-up was 297.5 days (range, 100-390 days), with 100% survival at 3 months., Conclusions: EVLP may facilitate assessment and/or reconditioning of borderline lungs, with a conversion rate of 46 % and good short-term survival., (Copyright © 2012 International Society for Heart and Lung Transplantation.
