Early and Mid-Term Results of Solid Organ Transplantation After Circulatory Death: A 4-Year Single Centre Experience

Background and Objectives: The use of controlled donation after circulatory death (cDCD) donors has significantly increased during the past decades and successfully expanded the donors’ pool. However, warm ischemia may have detrimental effects on graft function. Italian Law requires a no-touch period of at least 20 min, which is much longer compared to the 5 min accepted in most European countries. Materials and Methods This is an Italian single-centre retrospective review of all cDCD procedures performed from April 2021 to June 2025. Patients with severe brain injury undergoing withdrawal of life-sustaining therapy (WLST) were considered for cDCD. After cardiac arrest and a no-touch period of 20 min, organ reperfusion was performed using abdominal or thoraco-abdominal normothermic regional perfusion (NRP) through femoral vessels cannulation. The primary endpoint was 30-day graft survival; secondary endpoints included: incidence of primary non-function (PNF) and non-anastomotic biliary stricture (NAS) in liver transplantation, PNF and delayed graft function (DGF) in kidney transplantation, primary graft dysfunction (PGD) in heart and lung transplantation, and recipient’s survival. Results: A total of 52 patients, 33 (63%) males, median age 74 (65–79) years, underwent WLST during the study period and were included in the cDCD program. Median functional warm ischemic time (WIT), total WIT, asystolic phase, and NRP duration were 37 (34–40), 40 (37–42), 24 (23–26), and 192 (166–212) min, respectively. A total of 123 organs (46 livers, 61 kidneys, 8 hearts, and 8 lungs) were considered suitable for transplantation, procured, and successfully transplanted in 115 recipients. We report the early and mid-term outcomes of 84 recipients, including 41 liver recipients, 32 kidney recipients, and 8 heart recipients transplanted at the Azienda Ospedaliera Universitaria Integrata of Verona, and 3 lung recipients transplanted at the Azienda Ospedale Università of Padova. The 30-day graft survival was 95% in liver recipients, 97% in kidney recipients, and 100% in heart and lung recipients. PNF was observed in two liver recipients, and PGD in two lung recipients. DGF was recorded in 3 (9%) kidney recipients. Six recipients died during the follow-up, and the mean survival time was 3.9 ± 0.1 years. Conclusions: Solid organ transplantation using cDCD donors is feasible and provides excellent early and mid-term results despite longer donor asystolic times. Larger data and longer follow-up are necessary to confirm these promising results.
