When a child needs a liver transplant, the biggest hurdle is often finding a donor with a matching blood type. For years, doctors have looked at whether using a donor with an incompatible blood type—meaning the blood types do not match—impacts the long-term survival of these young patients. This analysis looked at survival rates over one, three, and five years.
The findings show that children who received livers from incompatible donors had survival rates comparable to those who received compatible ones. The data also showed no significant differences in graft survival, vascular or biliary complications, or common infections like CMV and EBV. This suggests that the mismatch in blood type does not seem to compromise the primary goals of the surgery.
However, there is one important detail to note. Patients with mismatched blood types did show a significantly higher rate of antibody-mediated rejection, which is when the body's immune system attacks the new organ. Because this specific finding was based on only four studies, the overall certainty of the data is very low. These results are based on observational studies, which can have a risk of bias.
