OBJECTIVES Historically, the perfusion-guided sequence suggests to first transplant the side with lowest lung perfusion. This sequence is thought to limit right ventricular afterload and prevent acute heart failure after first pneumonectomy. As a paradigm shift, we adopted the right-first implantation sequence, irrespective of lung perfusion. The right donor lung generally accommodates a larger proportion of the cardiac output. We hypothesized that the right-first sequence reduces the likelihood of oedema formation in the firstly transplanted graft during second-lung implantation. Our objective was to compare the perfusion-guided and right-first sequence for intraoperative extracorporeal membrane oxygenation (ECMO) need and primary graft dysfunction (PGD). METHODS A retrospective single-centre cohort study (2008–2021) including double-lung transplant cases (N  = 696) started without ECMO was performed. Primary end-points were intraoperative ECMO cannulation and PGD grade 3 (PGD3) at 72 h. Secondary end-points were patient and chronic lung allograft dysfunction-free survival. In cases with native left lung perfusion ≤50% propensity score adjusted comparison of the perfusion-guided and right-first sequence was performed. RESULTS When left lung perfusion was ≤50%, right-first implantation was done in 219 and left-first in 189 cases. Intraoperative escalation to ECMO support was observed in 10.96% of right-first versus 19.05% of left-first cases (odds ratio 0.448; 95% confidence interval 0.229–0.0.878; P  = 0.0193). PGD3 at 72 h was observed in 8.02% of right-first versus 15.64% of left-first cases (0.566; 0.263–1.217; P  = 0.1452). Right-first implantation did not affect patient or chronic lung allograft dysfunction-free survival. CONCLUSIONS The right-first implantation sequence in off-pump double-lung transplantation reduces need for intraoperative ECMO cannulation with a trend towards less PGD grade 3.

Objective To analyze the influencing factors of survival of patients with airway stenosis requiring clinical interventions after lung transplantation. Methods Clinical data of 66 patients with airway stenosis requiring clinical interventions after lung transplantation were retrospectively analyzed. Univariate and multivariate Cox’s regression models were adopted to analyze the influencing factors of survival of all patients with airway stenosis and those with early airway stenosis. Kaplan-Meier method was used to calculate the overall survival and delineate the survival curve. Results For 66 patients with airway stenosis, the median airway stenosis-free time was 72 (52,102) d, 27% (18/66) for central airway stenosis and 73% (48/66) for distal airway stenosis. Postoperative mechanical ventilation time [hazard ratio (HR) 1.037, 95% confidence interval (CI) 1.005-1.070, P=0.024] and type of surgery (HR 0.400, 95%CI 0.177-0.903, P=0.027) were correlated with the survival of patients with airway stenosis after lung transplantation. The longer the postoperative mechanical ventilation time, the higher the risk of mortality of the recipients. The overall survival of airway stenosis recipients undergoing bilateral lung transplantation was better than that of their counterparts after single lung transplantation. Subgroup analysis showed that grade 3 primary graft dysfunction (PGD) (HR 4.577, 95%CI 1.439-14.555, P=0.010) and immunosuppressive drugs (HR 0.079, 95%CI 0.022-0.287, P<0.001) were associated with the survival of patients with early airway stenosis after lung transplantation. The overall survival of patients with early airway stenosis after lung transplantation without grade 3 PGD was better compared with that of those with grade 3 PGD. The overall survival of patients with early airway stenosis after lung transplantation treated with tacrolimus was superior to that of their counterparts treated with cyclosporine. Conclusions Long postoperative mechanical ventilation time, single lung transplantation, grade 3 PGD and use of cyclosporine may affect the survival of patients with airway stenosis after lung transplantation.

Abstract Background Millions of people throughout the world suffer from the common and fatal respiratory disorder known as chronic obstructive pulmonary disease (COPD). Lung transplantation gives hope to individuals with end-stage COPD, with both bilateral lung transplantation and single lung transplantation being effective procedures. The complexity of chronic obstructive pulmonary disease is underscored by various factors influencing transplant outcomes, including patient characteristics, donor features, and complications post-transplantation. Methodology This narrative review explores recent studies on bilateral and single lung transplantation in chronic obstructive pulmonary disease patients, focusing on research published after 2020. Databases like PubMed and Google Scholar were used with keywords such as “COPD,” “lung transplantation,” “bilateral lung transplantation,” and “single lung transplantation” guided the research, emphasizing survival rates, quality of life, and post-transplant complications. Five selected articles encompassing 63,426 patients were examined, evaluating methodological variations among the studies. Results The selected studies showed no unanimous agreement on whether bilateral or single lung transplantation is superior for chronic obstructive pulmonary disease patients. Bilateral lung transplantation exhibited higher mid- and long-term survival rates, influenced significantly by age, comorbidities, and disease profiles. Improved quality of life was observed with bilateral transplantation, but this outcome depended on external circumstances. Post-transplant complications emphasized the need for rigorous post-transplant care. Conclusions Individualized assessments are crucial when choosing between bilateral and single lung transplantation for chronic obstructive pulmonary disease patients. Despite varying research results, bilateral transplantation generally offers better survival and quality of life. Informed decisions require personalized post-transplant care, standardized reporting, and consistent research methods. Emphasizing donor management, preventing chronic lung allograft dysfunction, and prioritizing patient-centered care is vital. Collaborative efforts and patient-focused strategies are essential for improving long-term outcomes in these patients undergoing lung transplantation.

• Vasoplegia is a common phenomenon during and after cardiac surgery. • There are few studies on the occurrence of intraoperative vasoplegia in lung transplant. • In this study, vasoplegia incidence in lung transplant is comparable to cardiac surgery. • Male sex and cystic fibrosis are risk factors for vasoplegia in lung transplant. Severe hypotension and low systemic vascular resistance in the setting of adequate cardiac output, known as "vasoplegic syndrome" (VS), is a physiologic disturbance reported in 9% to 44% of cardiac surgery patients. Although this phenomenon is well-documented in cardiac surgery, there are few studies on its occurrence in lung transplantation. The goal of this study was to characterize the incidence of VS in lung transplantation, as well as identify associated risk factors and outcomes. Retrospective study of single and bilateral lung transplants from April 2013 to September 2021. The study was conducted at an academic hospital. Patients ≥18 years of age who underwent lung transplantation. None. The authors defined VS as mean arterial pressure <65 mmHg, cardiac index ≥2.2 L/min/m2, and ≥30 minutes of vasopressor administration after organ reperfusion. The association between VS and risk factors or outcomes was assessed using t tests, Mann-Whitney U, and chi-square tests. The authors ran multivariate logistic regression models to determine factors independently associated with VS. The incidence of VS was 13.9% (CI 10.4%-18.4%). In the multivariate model, male sex (odds ratio 2.85, CI 1.07-7.58, p = 0. 04) and cystic fibrosis (odds ratio 5.76, CI 1.43-23.09, p = 0. 01) were associated with VS. The incidence of VS in lung transplantation is comparable to that of cardiac surgery. Interestingly, male sex and cystic fibrosis are strong risk factors. Identifying lung transplant recipients at increased risk of VS may be crucial to anticipating intraoperative complications. [ABSTRACT FROM AUTHOR]

Pulmonary arterial hypertension (PAH) is a rare heterogeneous disorder in the paediatric population which is mostly associated with congenital heart disease. The management of paediatric idiopathic PAH (IPAH) is difficult due to insufficient comparative data and depends on the results of evidence-based adult studies with several pulmonary vasodilators, as well as the clinical experiences of paediatric experts. Our aim was to present the case of a 9-year-old girl who underwent several methods of treatment, including pharmacotherapy with a significant reaction to treprostinil, as well as bilateral lung transplantation. The patient's treatment was distinguished by the fact that the dose escalation was as rapid as that observed in the adult population. Due to the limited current evidence and knowledge, the initiation of treatment for these patients remains an individual choice. On the grounds of the number of non-specific symptoms, the diagnosis of this patient was a long process and based mainly on the differential diagnosis. The purpose of this paper is to study this example in order to highlight the importance of early symptoms and the quick implementation of intensive treatment. The applied methods may be useful in doubtful diagnosis processes and treatment procedures in the paediatric population. [ABSTRACT FROM AUTHOR]

Open in new tab Download slide OBJECTIVES Total ischaemic time (IT) is considered a limiting factor in lung transplantation. In this retrospective study, we investigate effects of IT and disease burden on outcomes after bilateral lung transplantation. METHODS A total of 1298 patients undergoing bilateral lung transplantation between January 2010 and May 2022 (follow-up 100%, median 54 months) were included. Pre-transplant diseases' severity (recipient body mass index, recipient age, previous lung transplantation, Tacrolimus immunosuppression, preoperative recipient extracorporeal membrane oxygenation support, lung volume reduction) for graft failure was individually calculated and—as IT—categorized. Vice versa adjusted Cox models were calculated. Considering competing risks, we assessed cumulative incidences of airway obstructive complications and chronic lung allograft dysfunction with death as competing risk factors for primary graft dysfunction were assessed by binary logistic regression. RESULTS Higher disease burden significantly accelerated chronic lung allograft dysfunction and death occurrence (P  < 0.001); IT did not. IT-adjusted disease burden strata showed 50% graft survival differences at 11 years after transplantation (range 24–74%), disease burden-adjusted IT strata 18% for all and 6% (54–60%) among those above 7 h. All significant primary graft dysfunction risk factors were diagnoses related, IT was not significantly important and odds ratios did not increase with IT. CONCLUSIONS The eventual graft survival disadvantage that results from an IT between 7 and at least 11 h is negligible in contrast to frequent recipients' disease-based risk levels.

Background: In recent decades, the incidence of multidrug-resistant (MDR) and extended-spectrum β-lactamase (ESBL) gram-negative (GN) bacteria has increased progressively among lung transplantation (LT) recipients. A prompt diagnosis, prevention, and management of these pathogens remain the cornerstone for successful organ transplantation.Research Question: What are the incidence of MDR and ESBL GN bacteria within the first 30 days after LT and related risk of in-hospital mortality? What are the potential clinical predictors of isolation of MDR and ESBL GN bacteria?Study Design and Methods: All consecutive LT recipients admitted to the ICU of the University Hospital of Padua (February 2016-December 2021) were screened retrospectively. Only adult patients undergoing the first bilateral LT and not requiring invasive mechanical ventilation, extracorporeal membrane oxygenation, or both before surgery were included. MDR and ESBL GN bacteria were identified using in vitro susceptibility tests and were isolated from the respiratory tract, blood, urine, rectal swab, or surgical wound or drainage according to a routine protocol.Results: One hundred fifty-three LT recipients were screened, and 132 were considered for analysis. Median age was 52 years (interquartile range, 41-60 years) and 46 patients (35%) were women. MDR and ESBL GN bacteria were identified in 45 patients (34%), and 60% of patients demonstrated clinically relevant infection. Pseudomonas aeruginosa (n = 22 [49%]) and Klebsiella pneumoniae (n = 17 [38%]) were frequently isolated after LT from the respiratory tract (n = 21 [47%]) and multiple sites (n = 18 [40%]). Previous recipient-related colonization (hazard ratio [HR], 2.48 [95% CI, 1.04-5.90]; P = .04) and empirical exposure to broad-spectrum antibiotics (HR, 6.94 [95% CI, 2.93-16.46]; P < .01) were independent predictors of isolation of MDR and ESBL GN bacteria. In-hospital mortality of the MDR and ESBL group was 27% (HR, 6.38 [95% CI, 1.98-20.63]; P < .01).Interpretation: The incidence of MDR and ESBL GN bacteria after LT was 34%, and in-hospital mortality was six times greater. Previous recipient-related colonization and empirical exposure to broad-spectrum antibiotics were clinical predictors of isolation of MDR and ESBL GN bacteria. [ABSTRACT FROM AUTHOR]

Background: Single lung transplantation (SLT) is associated with worse long-term outcomes than bilateral lung transplantation (BLT), but often is performed in older adults at risk of not tolerating BLT., Research Question: How do the outcomes of SLT and BLT compare among older adult recipients?, Study Design and Methods: The Scientific Registry of Transplant Recipients database (2005-2022) was queried for lung transplant recipients 65 years of age or older. Patients were stratified by whether they underwent BLT or SLT and were propensity matched. Baseline characteristics and morbidity were compared with frequentist statistics. Survival was analyzed via Kaplan-Meier estimation. Risk factors for mortality were identified with Cox regression., Results: Of 9,904 included patients, 4,829 patients (48.8%) underwent SLT. Patients who underwent SLT had lower lung allocation scores (39.6 vs 40.6; P < .001), more interstitial lung disease (74.4% vs 64.6%; P < .001), and lower rates of bridging (0.7% vs 2.4%; P < .001). Groups did not differ significantly by sex, BMI, or donor characteristics. Propensity matching resulted in 2,539 patients in each group. On matched analysis, patients undergoing SLT had shorter lengths of stay (14 days vs 18 day), lower reintubation rates (14.7% vs 19.8%), and less postoperative dialysis use (4.2% vs 6.4%; P < .001 for all). Patients who underwent SLT had comparable survival at 30 days (97.6% vs 97.3%; P = .414) and 1 year (85.5% vs 86.3%; P = .496), but lower survival at 5 years (45.4% vs 53.4%; P < .001) on matched analysis. SLT was a risk factor for 5-year mortality (adjusted hazard ratio, 1.19; P < .001)., Interpretation: In older adults, SLT is associated with less morbidity and comparable early survival relative to BLT, but lower 5-year survival. SLT is reasonable to perform in older adults at high risk of not tolerating BLT., Competing Interests: Financial/Nonfinancial Disclosures None declared., (Copyright © 2024 The Author(s).

Pulmonary arteriovenous fistula (PAVF) is a rare pulmonary vascular lesion, more than 80% of which is caused by congenital abnormal development of pulmonary capillaries. The incidence of PAVF ranges from 2/100,000 to 3/100,000, with no difference in the male and female ratio. Congenital PAVF is often associated with hereditary hemorrhagic telangiectasia (HHT). In this article, we report a patient with only congenital PAVF that was successfully treated by bilateral lung transplantation (BLT) with intraoperative venovenous extracorporeal membrane oxygenation (ECMO) support because both lungs have been affected by PAVF and secondary pulmonary hypertension. To the best of our knowledge, this is the first report of BLT for PAVF in China and the second report that explains the clinical course of a patient to receive BLT for congenital PAVF without HHT. Some investigators have proposed lung transplantation as a definitive treatment, but the results are controversial. On the basis of the current condition of this patient, we believe lung transplantation is a viable option for certain patients, but the long-term effect remains to be studied.

We investigated whether RV function recovers in children with pulmonary arterial hypertension (PAH) and RV failure undergoing lung transplantation (LuTx). Prospective observational study of 15 consecutive children, 1.9 to 17.6 years old, with PAH undergoing bilateral LuTx. We performed advanced echocardiography (Echo) and cardiac magnetic resonance imaging (MRI), followed by conventional and strain analysis, pre- and ∼6 weeks post-LuTx. After LuTx, RV/LV end-systolic diameter ratio (Echo), RV volumes and systolic RV function (RVEF 63 vs 30 %; p < 0.05) by MRI completely normalized, even in children with severe RV failure (RVEF < 40%). The echocardiographic end-systolic LV eccentricity index nearly normalized post-LuTx (1.0 vs 2.0, p < 0.0001) while RV hypertrophy regressed more slowly and was still evident. We found especially the end-systolic RV/LV ratios by Echo (diameter: 0.6 vs 2.6) or MRI (volumes: 0.8 vs 3.4) excellent diagnostic tools (p < 0.05): Together with RVEF by MRI, these ratios were superior to tricuspid annular plane systolic excursion (TAPSE; p = 0.4551) in assessing global systolic RV dysfunction. Moreover, children with severe PAH had reduced RV 2D longitudinal strain (Echo, MRI; p = 0.0450) and decreased RV 2D radial and circumferential strain (MRI; p = 0.0026 and p = 0.0036 respectively), all of which greatly improved following LuTx. We demonstrate full recovery of RV systolic function in children within two months after LuTx for severe PAH, independently of the patients' age, weight, and hemodynamic compromise preceding the LuTx. Even in end-stage pediatric PAH with poor RV function and low cardiac output, LuTx should be preferred over heart-lung transplantation. [ABSTRACT FROM AUTHOR]

Bronchiolitis obliterans (BO) is a severe complication of Castleman disease (CD), a rare lymphoproliferative disease with unclear pathogenesis. Currently, there are no reports on the safety or outcomes of bilateral lung transplantation in patients with BO due to CD. This study aimed to characterize the clinical manifestations and features of BO and CD. We retrospectively analyzed the medical records of six consecutive patients with BO and CD who underwent bilateral lung transplantation between December 2012 and December 2020. The average age of patients at lung transplantation was 33 ± 15 years, and the age range of patients at diagnosis of CD was about 9–56 years. The body mass index was 15.2 ± 1.9 kg/m2. The average time from diagnosis to lung transplantation was 4.1 ± 2.7 years. All the patients had unicentric CD (UCD); five had concomitant paraneoplastic pemphigus, and four received extracorporeal membrane oxygenation during surgery. The average hospital stay was 51 ± 53 days. Infection was the most common postoperative complication. CD did not recur in any of the patients. Thus, bilateral lung transplantation is a viable and safe treatment for selected patients with CD and BO, which can improve the quality of life and prolong survival. [ABSTRACT FROM AUTHOR]

Background: Destroyed lung can cause mediastinal displacement and asymmetric chest deformity. Reports on bilateral lung transplantation (LT) to treat destroyed lung and asymmetric chest deformity are rare. This study presents our surgical experience of bilateral LT among patients with destroyed lung and asymmetric chest deformity.Methods: Six patients with destroyed lung and asymmetric chest deformity who underwent bilateral LT at our center from 2005 to 2020 were included in the study. Demographic data, technical data, perioperative details, and short-term follow-up data were reviewed.Results: Three patients underwent bilateral LT via anterolateral incisions in the lateral position without sternal transection, while three patients underwent bilateral LT via clam-shell incisions in the supine position with sternal transection. Only one patient required intraoperative extracorporeal membrane oxygenation. Four patients underwent size-reduced LT. In the other two patients, we restored the mediastinum by releasing mediastinal adhesions to ensure maximal preservation of the donor lung function. Patients in the lateral position group had a higher volume of blood loss, longer operation time, and longer postoperative in-hospital stay than those in the supine position group. However, these differences were not statistically significant. Postoperative computed tomography in the supine position group revealed that the donor lungs were well expanded and the mediastina were in their original positions.Conclusions: Although bilateral LT in patients with destroyed lung and asymmetric chest deformity is high risk, with sufficient preoperative preparation and evaluation, it is safe and feasible to perform bilateral LT for selected patients. For patients without severe chest adhesions, releasing the mediastinal adhesions and restoring the mediastinum through a clam-shell incision in the supine position is a simple and effective method to maximally preserve the donor lung function without pneumonectomy or lobectomy.

Objective To improve the surgical efficacy of bilateral lung transplantation for pediatric cystic fibrosis through multi-disciplinary team (MDT). Methods Preoperative MDT consultation was delivered for a 10-year-old child with rare end-stage cystic fibrosis to establish the corresponding treatment protocol. Results The child was diagnosed with cystic fibrosis for 5 years, and the indication of lung transplantation were confirmed. After preoperative MDT consultation, bilateral lung transplantation via a Clam-shell incision was determined. The vital signs were maintained stable during operation. Postoperatively, ventilator-assisted ventilation, anti-infection, immunosuppression, acid suppression, prevention of stress ulceration and other treatments were delivered. Individualized treatment was given according to the characteristics of the child, and the child was well recovered. Conclusions Through preoperative MDT consultation, lung transplantation yields satisfactory surgical efficacy in treating pediatric cystic fibrosis and lowers the risk of postoperative complications, which deserves application in clinical practice.

Summary: This study evaluated the impact of unilateral diaphragm elevation following bilateral lung transplantation on postoperative course. Patient data for all lung transplantations performed at our institution between 01/2010 and 12/2019 were reviewed. Presence of right or left diaphragm elevation was retrospectively evaluated using serial chest X‐rays performed while patients were standing and breathing spontaneously. Right elevation was defined by a > 40 mm difference between right and left diaphragmatic height. Left elevation was present if the left diaphragm was at the same height or higher than the right diaphragm. In total, 1093/1213 (90%) lung transplant recipients were included. Of these, 255 (23%) patients exhibited radiologic evidence of diaphragm elevation (right, 55%; left 45%; permanent, 62%). Postoperative course did not differ between groups. Forced expiratory volume in 1 second, forced vital capacity and total lung capacity were lower at 1‐year follow‐up in patients with permanent than in patients with transient or absent diaphragmatic elevation (P = 0.038, P < 0.001, P = 0.002, respectively). Graft survival did not differ between these groups (P = 0.597). Radiologic evidence of diaphragm elevation was found in 23% of our lung transplant recipients. While lung function tests were worse in patients with permanent elevation, diaphragm elevation did not have any relevant impact on outcomes. [ABSTRACT FROM AUTHOR]

Background: Thoracic transplantation is considered for patients with Eisenmenger syndrome (ES) who have refractory right ventricular failure despite optimal therapy for pulmonary arterial hypertension. This study compared the outcomes of bilateral lung transplantation (BLT) with cardiac defect repair vs combined heart-lung transplantation (HLT).Research Question: This study presents an updated analysis using a US national registry to evaluate the outcomes of patients diagnosed with ES who underwent HLT or BLT with repair of cardiac defects.Study Design and Methods: This study identified patients with ES who underwent thoracic transplantation from 1987 to 2018 from the United Network for Organ Sharing database. Survival curves were estimated by using the Kaplan-Meier method and were compared by using the log-rank test.Results: During the study period, 442 adults with ES underwent thoracic transplantation (316 HLTs and 126 BLTs). Following BLT, overall survival 1, 5, and 10 years' posttransplant was 63.1%, 38.5%, and 30.2%, respectively. Following HLT, overall survival 1, 5, and 10 years' posttransplant was 68.0%, 47.3%, and 30.5% (P = .6). When survival analysis was stratified according to type of defect, patients with an atrial septal defect had better survival following BLT than following HLT (88.3% vs 63.2% 1 year posttransplant, P < .01; 71.1% vs 49.8% 3 years' posttransplant, P < .01; and 37.4% vs 29.9% 10 years' posttransplant, P = .08). Patients with a ventricular septal defect (VSD) exhibited better survival following HLT than following BLT (78.2% vs 49.6% 1 year posttransplant, P < .01; 55.6% vs 34.3% 5 years' posttransplant, P < .01; and 35.7% vs 26.5% 10 years' posttransplant, P = .03). The most common cause of mortality in patients with VSD undergoing BLT was cardiac ventricular failure.Interpretation: This study suggests that the best transplant option for patients with VSD remains HLT, which prevents subsequent development of ventricular failure. BLT with cardiac defect repair should be considered as the first-line treatment option in patients with ES due to an uncorrected atrial septal defect. These patients can be considered to have isolated and reversible right ventricular failure akin to patients with advanced pulmonary arterial hypertension. [ABSTRACT FROM AUTHOR]

Background: Lung transplantation, either single or bilateral, serves as the only effective treatment for end‐stage idiopathic pulmonary fibrosis (IPF), but their superiority is still being debated, and its application in Chinese patients has not been data analysed. Methods: We reviewed 109 IPF patients who received lung transplantation at our centre between January 1, 2015 and December 31, 2017. The patients were divided into single lung transplantation (SLT) group and bilateral lung transplantation (BLT) group. We compared the two groups' demographic characteristics and clinical indexes (intraoperative conditions, postoperative complications, follow‐ups and life qualities). Results: Patients in BLT group were significantly younger than those in SLT group (P < 0.001), and had more pretransplant infections (P = 0.007). The total ischemic time (P < 0.001) was shorter and intraoperative blood loss was less (P = 0.001) in SLT group. No significant difference was found in the proportion of patients in using anti‐fibrosis drugs, pulmonary artery pressure, extracorporeal membrane oxygenation during the surgery; the length of intensive care unit stay; the incidence of complication; and the overall survival rate between two groups. However, the hierarchical analysis found that patients aged > 60 years showed a better survival in SLT group (P = 0.008). Both groups got normal MOS 36‐item Short Form (SF‐36) scores, and the scores of BLT were higher than those of SLT. The BLT group had better lung function than SLT group 1 year post‐lung transplantation. Conclusions: Both SLT and BLT are effective and SLT is more favourable for the patients of > 60 years.

OBJECTIVES We introduced an extubation strategy for emphysema patients after bilateral lung transplantation. Patients who met the extubation criteria were extubated in the operating room (OR) followed by non-invasive ventilation, and the other patients were extubated in the intensive care unit (ICU). The primary objective was to determine the extubation rate. The secondary outcomes were to determine the factors allowing for extubation in the OR and the postoperative course. METHODS This study is a single-centre retrospective database analysis of 96 patients. Anaesthesia was performed using automated titration of total intravenous anaesthesia combined with thoracic epidural analgesia. Extubation criteria included arterial partial pressure oxygen (PaO2)/fraction of inspired oxygen (FiO2) ratio, chest radiograph, oedema and haemodynamic stability. Data were compared using non-parametric tests and expressed as median (interquartile ranges) or number (%). RESULTS Fifty-three (55%) patients were extubated in the OR (the OR group) with 1 requiring reintubation and 43 (45%) patients were extubated in the ICU (the ICU group). Preoperative pulmonary hypertension, the requirement for intraoperative extracorporeal membrane oxygenation (ECMO), bleeding and ex vivo lung reconditioning donors were lower in the OR group. At the end of the procedure, the PaO2/FiO2ratio was better [352 (289–437) vs 206 (144–357), P = 0.004), and the need for postoperative ECMO, mechanical ventilation duration, length of stay in the ICU [5 (4–7) vs 12 (8–20) days, P < 0.0001], Grade 3 primary graft dysfunction at 72 h [1 (2%) vs 10 (24%), P = 0.002] and 1-year mortality [5 (9%) vs 11 (26%) patients, P = 0.014] were lower in the OR group than in the ICU group. CONCLUSIONS Half of patients were extubated in the OR, and this strategy does not require additional ICU resources. [ABSTRACT FROM AUTHOR]

This article examines the existing literature regarding single (SLT) and bilateral lung transplantation (BLT) to help answer the question of which approach is preferable. Specifically, this review highlights the following subjects: disease-specific indications for SLT versus BLT; the impact of procedure type on posttransplantation functional status; the impact of procedure type on posttransplantation quality of life; chronic rejection after lung transplantation; ethical challenges facing the choice between single and bilateral transplants; and, novel strategies in this arena., (Copyright © 2022 Elsevier Inc.

We report on two patients who underwent bilateral lung transplantation (BLTx) combined with cardiac surgery. Patient 1 was a female whose pulmonary hypertension resulted from a congenital atrial septal defect (ASD) and idiopathic pulmonary arterial hypertension. She had a very small left ventricle (LV). We initiated venoarterial extracorporeal membrane oxygenation (ECMO) before induction of general anesthesia. She underwent ASD patch closure, pulmonary artery replacement, and BLTx under cardiopulmonary bypass (CPB). At the weaning from CPB, primary graft dysfunction and pulmonary edema induced by LV diastolic dysfunction was apparent. We gradually decreased the ECMO support and eventually weaned off the ECMO on the 4th postoperative day (POD) and the ventilator on the 29th POD. Patient 2 was a male with Eisenmenger syndrome, which resulted from ASD and ventricular septal defect (VSD). He had a normal LV. General anesthesia was induced smoothly without ECMO. He underwent ASD and VSD patch closure, pulmonary artery replacement, and BLTx under CPB. Weaning from CPB proceeded smoothly. These patients needed different management because of their different LV function. Especially, perioperative management of the BLTx patient with LV diastolic dysfunction was difficult. Assessment of perioperative cardiac function is very important in BLTx combined with cardiac surgery. [ABSTRACT FROM AUTHOR]
