The shortage of “ideal” donors suitable for lung procurement has led to an increasing use of extended criteria organ donors (Extended Criteria Donors, ECD). However, concerns regarding post-transplant outcomes compared with standard donors persist in the literature. This study presents a retrospective analysis of lung transplantations performed at the Padua Transplant Center between January 2021 and December 2024. Recipients were divided into two groups based on donor characteristics: standard donors and extended criteria donors. Donor, recipient, and perioperative variables were analyzed. Primary outcomes included early graft function, incidence of primary graft dysfunction (PGD), the need of extracorporal support (ECMO), postoperative complications, and short- and mid-term survival. During the study period, the use of extended criteria donors progressively increased, contributing to the expansion of the donor pool. Early postoperative outcomes, including PGD rates and length of intensive care unit stay, were comparable between the two groups. No significant differences were observed in short- and mid-term survival. The use of extended criteria donors represents a safe and effective strategy to address organ shortage in lung transplantation. In the experience of the Padua Transplant Center, careful selection of marginal donors allowed outcomes comparable to those achieved with standard donors, supporting their clinical use.
La carenza di donatori "ideali" idonei all'espianto di polmone ha portato a un crescente utilizzo di donatori di organo a criteri estesi (Extended Criteria Donors, ECD). Nella letteratura tuttavia permangono dubbi riguardo agli outcome post-trapianto rispetto ai donatori standard. Questo lavoro presenta un’analisi retrospettiva dei trapianti di polmone eseguiti presso il Centro Trapianti di Padova tra gennaio 2021 e Dicembre 2024. I riceventi sono stati suddivisi in due gruppi in base alle caratteristiche del donatore: donatori standard e donatori a criteri estesi. Sono state analizzate variabili del donatore, del ricevente e perioperatorie. Gli outcome primari hanno incluso la funzione precoce dell’organo trapiantato, l’incidenza di disfunzione primaria del graft (PGD), la necessità di supporto extracorporeo (ECMO), le complicanze postoperatorie e la sopravvivenza a breve e medio termine. Nel periodo di studio, l’utilizzo di donatori a criteri estesi è aumentato progressivamente, contribuendo all’espansione del pool di donatori. Gli outcome postoperatori precoci, inclusi i tassi di PGD e la durata della degenza in terapia intensiva, sono risultati sovrapponibili tra i due gruppi. Non sono emerse differenze significative nella sopravvivenza a breve e medio termine. L’impiego di donatori a criteri estesi rappresenta una strategia sicura ed efficace per far fronte alla carenza di organi nel trapianto polmonare. Nell’esperienza del Centro Trapianti di Padova, un’accurata selezione dei donatori marginali ha consentito di ottenere risultati comparabili a quelli dei donatori standard, supportandone l’utilizzo clinico.

Abstract
The shortage of “ideal” donors suitable for lung procurement has led to an increasing use of extended criteria organ donors (Extended Criteria Donors, ECD). However, concerns regarding post-transplant outcomes compared with standard donors persist in the literature. This study presents a retrospective analysis of lung transplantations performed at the Padua Transplant Center between January 2021 and December 2024. Recipients were divided into two groups based on donor characteristics: standard donors and extended criteria donors. Donor, recipient, and perioperative variables were analyzed. Primary outcomes included early graft function, incidence of primary graft dysfunction (PGD), the need of extracorporal support (ECMO), postoperative complications, and short- and mid-term survival. During the study period, the use of extended criteria donors progressively increased, contributing to the expansion of the donor pool. Early postoperative outcomes, including PGD rates and length of intensive care unit stay, were comparable between the two groups. No significant differences were observed in short- and mid-term survival. The use of extended criteria donors represents a safe and effective strategy to address organ shortage in lung transplantation. In the experience of the Padua Transplant Center, careful selection of marginal donors allowed outcomes comparable to those achieved with standard donors, supporting their clinical use.| File | Dimensione | Formato | |
