Resultados del retrasplante pulmonar por disfunción crónica del injerto pulmonar en un centro trasplantador: Hospital Vall D’Hebron de Barcelona / Lung Retransplantation Due to Chronic Lung Allograph Dysfunction: Results From a Spanish Transplant Unit

Introducción: La supervivencia del trasplante pulmonar (TP) viene condicionada fundamentalmente por el desarrollo de disfunción crónica del injerto (DCI). El retrasplante pulmonar (RP) es una alternativa para una población seleccionada con DCI. El objetivo del estudio fue revisar la experiencia de RP en nuestro centro. Pacientes y métodos: Se ha realizado un estudio retrospectivo de los pacientes sometidos a RP entre agosto de 1990 y julio de 2017. Resultados: Se realizaron 14 RP de un total de 998 (1,4%) TP. Doce RP se dieron por causa de DCI: 10 (71,4%) por síndrome de bronquiolitis obliterante y 2 (14,3%) por síndrome restrictivo del injerto. En 2 pacientes el RP se realizó en los 30 días siguientes al primer TP. En el RP por DCI el tiempo medio entre el TP y el RP fue de 48 meses. Tras el RP el tiempo medio de ventilación mecánica fue de 32 días. El incremento del FEV1 tras el RP fue del 24 ± 18%. Los mejores valores en la espirometría se observaron a los 7,3 meses. La supervivencia media de la serie fue de 43,8 meses, en los pacientes con síndrome de bronquiolitis obliterante fue de 63,4 meses mientras que en los pacientes con síndrome restrictivo del injerto fue de 19,5 meses. Solo un paciente de los 2 RP precoces sobrevivió a este. Conclusión: El RP es una opción terapéutica en pacientes seleccionados con DCI. Sin embargo, estos resultados no son reproducibles si el RP se realiza en los primeros días

Introduction: Long-term survival of lung transplantation (LT) patients is mainly limited by the development of chronic lung allograft dysfunction (CLAD). Lung retransplantation (LR) is an alternative for a selected population. The aim of this study was to review the LR experience in our center. Patients and methods: We conducted a retrospective study of patients undergoing LR between August 1990 and July 2017. Results: Fourteen LR out of a total of 998 (1.4%) LT were performed. Twelve patients (85.7%) underwent LR due to CLAD: 10 (71.4%) because of bronchiolitis obliterans syndrome and 2 (14.3%) due to restrictive allograft syndrome. LR was performed in 2 patients within 30 days of the first LT. In those who underwent LR due to CLAD, mean time between the first LT and LR was 48 months, and mean duration of invasive mechanical ventilation was 32 days. The increase in FEV1 after LR was 24 ± 18%. The best spirometry values were observed after 7.3 months. Mean survival of the cohort was 43.8 months. In patients with bronchiolitis obliterans syndrome, mean survival was 63.4 months, while in those with restrictive allograft syndrome, it was 19.5 months. Only 1 of the 2 early LR patients survived. Conclusion: LR is a therapeutic option in selected patients with CLAD, with acceptable survival. Indication for LR early after LT shows poor outcomes
