Short-term evolution of renal transplant with grafts from donation after cardiac death: Type III Maastricht category.

BACKGROUND: Kidney transplantation from donors after cardiac death (Type III Maastricht category) is a therapeutic option for patients with terminal renal failure.

MATERIALS AND METHODS: We present a cohort of 8 patients who received a kidney transplant from donors after cardiac death (DCD). We analyzed the analytical results for the first 6 months after transplantation.

RESULTS: We included 8 cases of kidney transplants with organs from DCD (Type III Maastricht category). The mean age of donors was 58.40 ± 4.39 years and 3 (60%) were male. The mean creatinine (Cr) level prior to death was 1.10 ± 0.36 mg/dL. The mean age of recipients was 59.88 ± 10.58 years and 7 (87.5%) were male. Seven patients (87.5%) were on hemodialysis, whereas only 1 (12.5%) was on peritoneal dialysis. The median time on renal replacement therapy was 18 months (range, 2-76). Mean total warm ischemia time (WIT) was 24.88 ± 6.72 minutes, whereas the mean real WIT was 20.13 ± 4.51 minutes. The mean cold ischemia time (CIT) was 6 hours and 12 minutes ± 2 hours. Preimplantation biopsy showed acute tubular necrosis (extensive 40%). Tubular atrophy was mild in 100% of cases. After transplantation, 6 patients (75%) had delayed graft function requiring dialysis sessions whereas 2 patients (25%) did not require renal replacement therapy. Mean Cr level at 1, 3, and 6 months after transplantation was 2.37, 1.75, and 1.17 mg/dL, respectively.

CONCLUSION: Kidney transplantation with grafts from donors after cardiac arrest Maastricht Type III evolves favorably in the short term. According to preliminary results, controlled asystole donation could be an effective alternative to transplantation.
