RESUMO

Introducción: El trasplante cardiopulmonar (TCP) ha presentado una disminución progresiva en el número de procedimientos. En nuestro país existe poca información al respecto, siendo el objetivo de este estudio analizar la experiencia de un hospital de referencia. Métodos: Estudio observacional unicéntrico de una cohorte histórica en el periodo entre 1990 y 2021. Las asociaciones entre categorías se evaluaron mediante la prueba de X2 o la f de Fisher. La supervivencia se analizó a través del método de Kaplan-Meier. Las diferencias se evaluaron con el estudio de log-rank y el análisis multivariante con el método de Cox. Resultados: Se observó una reducción del número de procedimientos realizados en el último decenio (2000-2009: 19 [44,2%]; 2010-2021: 15 [34,8%]). La mortalidad posoperatoria precoz fue de 23,3%, reduciéndose a 13,3% a partir del 2010. La intrahospitalaria fue de 41%, disminuyendo a 33% en 2010. Los factores asociados a la mortalidad fueron cirugía torácica previa, corticoterapia, circulación extracorpórea (CEC) mayor a 200 min, tiempo de isquemia mayor a 300 min y dehiscencia traqueal (p < 0,005). La supervivencia global a uno, cinco y 10 años fue de 58, 44,7 y 36,1%, respectivamente. Los factores asociados a menores tasas de supervivencia fueron cirugía torácica previa, donante masculino, CEC mayor 200 min, tiempo de isquemia mayor a 300 min, dehiscencia traqueal y diferencia de pesos (p < 0,005). Conclusiones: Existe una disminución en el número de procedimientos, siendo más evidente en la última década, pero evidenciando una mejora tanto de la mortalidad posoperatoria y supervivencia.(AU)


Introduction: Heart–lung transplantation has shown a progressive decrease in the number of procedures. There is a lack of information about this field in Spain. The main goal of this study is to analyze the experience of a national reference hospital. Methods: We performed a retrospective study of a historical cohort of heart–lung transplanted patients in a single center, during a 30 years period (from 1990 to 2021). The associations between variables were evaluated using the χ2 test or Fisher's exact test. Survival was analyzed using the Kaplan–Meier method. Differences were evaluated using the log-rank test and multivariate analysis with the Cox method. Results: A decrease in the number of procedures performed in the last decade was observed [2000–2009: 19 procedures (44.2%); 2010–2021: 15 procedures (34.8%)]. Early postoperative mortality was 23.3%, falling to 13.3% from 2010. In-hospital mortality was 41%, falling to 33% from 2010. Main factors related to higher mortality: previous thoracic surgery, corticosteroid therapy, extracorporeal circulation (ECLS) greater than 200 min, ischemia time greater than 300 min, and tracheal dehiscence (p < 0.005). Overall survival at one, five, and ten years was 58%, 44.7%, and 36.1%, respectively. Factors associated with lower survival rates: previous thoracic surgery, male donor, extracorporeal circulation greater than 200 min, ischemia time greater than 300 min, tracheal dehiscence and weight difference (p < 0.005). Conclusions: There has been a progressive decrease in the number of heart–lung transplantations, being more evident in the last decade, but showing an improvement in both mortality and survival.(AU)

RESUMO

ANTECEDENTES Y OBJETIVOS: El retrasplante pulmonar (RTP) es un tratamiento válido en pacientes con disfunción pulmonar, pero con una elevada morbimortalidad. Nuestro objetivo es analizar nuestra experiencia en RTP en supervivencia y función pulmonar. PACIENTES Y MÉTODOS: Estudio retrospectivo de pacientes con RTP (1990-2019). VARIABLES: receptores y procedimiento, mortalidad precoz, supervivencia y función pulmonar en pacientes CLAD. Variables cuantitativas (media±DE); cualitativas (%). Se utilizó el test t de Student o χ2. La supervivencia se estimó mediante Kaplan-Meier, comparándose con Log Rank. Se estableció como significativa p < 0,05. RESULTADOS: De 784 pacientes trasplantados, 25 pacientes (edad media 38,41 ± 16,3 años, 12 hombres y 13 mujeres) fueron RTP; CLAD (n = 19), infarto pulmonar (n = 2), complicaciones de vía aérea (n = 2), disfunción del injerto (n = 1), rechazo hiperagudo (n = 1). Tiempo medio hasta el retrasplante: 5,41 ± 3,87 años en CLAD y 21,2 ± 21,4 días en no CLAD. La mortalidad a 90 días fue del 52% y 36,8% en el segundo periodo (p = 0,007), siendo mayor en pacientes que precisaron ECMO preoperatorio (80 vs. 20%, p = 0,04). La supervivencia a 1 y 5 años fue del 53,9% y 37,7%, respectivamente (p = 0,016). La supervivencia del grupo CLAD fue mayor (p = 0,08). El ECMO pre RTP disminuyó la supervivencia (p = 0,032). FEV1 mejoró una media de 0,98 ± 0,13L (25,6 ± 18,8%) (p = 0,001). CONCLUSIONES: El RTP es un procedimiento de elevada mortalidad que obliga a una cuidadosa selección de los pacientes, con mejores resultados en aquellos con CLAD. La función pulmonar de los pacientes con CLAD mejoró significativamente


BACKGROUND: Lung retransplantation (LR) is a valid choice with a significant risk of perioperative morbidity and mortality in selected patients with graft dysfunction after lung transplantation. Our goal is to analyse our experience in LR in terms of survival and lung function. METHODS: Retrospective study of patients undergoing LR (1990-2019). VARIABLES: recipients and procedure, early mortality, survival and lung function in patients with CLAD. Quantitative variables (mean±SD); qualitative (%). Student's t test or χ2 was used. Survival was estimated using Kaplan-Meier, compared with Log Rank. A p < 0.05 was established as significant. RESULTS: Of 784 transplanted patients, 25 patients (mean age 38.41-16.3 years, 12 men and 13 women) were LR; (CLAD (n = 19), pulmonary infarction (n = 2), airway complications (n = 2), graft dysfunction (n = 1), hyperacute rejection (n = 1), mean time to retransplantation: 5.41 ± 3.87 years in CLAD and 21.2 ± 21.4 days in non-CLAD. The 90-day mortality was 52% and 36.8% in the second period (p = 0.007), being higher in patients who required preoperative ECMO (80 vs. 20%, p = 0.04). The 1- and 5-year survival was 53.9% and 37.7%, respectively (p = 0.016). Survival of the CLAD group was greater (p = 0.08). Pre LR ECMO decreased survival (p = 0.032). After LR, FEV1 improved an average of 0.98 ± 0.13L (25.6 ± 18.8%) (p = 0.001). CONCLUSIONS: LR is a high mortality procedure that requires careful selection of patients with better results in patients with CLAD. The lung function of patients with CLAD improved significantly
