Arthur Ransom developed parvovirus, also known as slapped cheek syndrome, while in the womb, leading to severe health complications. According to multiple reports, his organs were failing, his heart was enveloped in fluid, and he was severely anemic. His mother, Maisie Ransom, told the Daily Mirror that doctors said without intervention he would not have survived much longer.
The intrauterine transfusion was performed at St George's Hospital in London. According to the Daily Mirror, Maisie Ransom was told the procedure had a 50/50 chance of success. She described the experience as terrifying, noting that doctors were working within millimetres because Arthur was so small. She said that without the donated blood, he would not have made it.
Intrauterine transfusions require very specific blood from a small number of donors, typically men, according to multiple reports. NHS Blood and Transplant issues about 180 units for intrauterine transfusions each year. The blood must meet strict criteria to ensure safety for the particularly vulnerable patients.
Paul Bickley is one of eight donors whose blood has been used most often for intrauterine transfusions, according to major media reports. He told BBC News that hearing his blood was used in this way almost made him cry. David Smith, a donor from Westminster, also contributes regularly. He told BBC News that if you can help babies, you have to, and that it is always a pleasure.
According to BBC News, Dr Anne Kelly, a paediatric transfusion and components clinical expert for NHS Blood and Transplant, said intrauterine transfusions are very rare, donors are carefully selected, and extra safety measures are applied because patients are particularly vulnerable.
Arthur Ransom is now a healthy baby reaching all milestones, according to his mother. She told the Daily Mirror that he is a chirpy little boy who keeps them on their toes. She expressed immense gratitude to blood donors, saying she often wonders who donated the blood that saved her son's life and would love to tell them that their decision gave her boy the chance to be here.
The exact survival rate for intrauterine transfusions at 16 weeks is not known, nor is the number of transfusions performed on fetuses younger than 16 weeks. The specific type of parvovirus that caused Arthur's condition and how common it is to cause severe fetal anemia also remain unclear. Long-term health outcomes for babies who receive intrauterine transfusions are not fully documented, and the exact number of eligible donors and the strict criteria for donation are not publicly detailed.
