Baby saved by prenatal transfusion at 16 weeks is now thriving at a year old

A baby thought to be the youngest in the United Kingdom to obtain a blood transfusion (at 16 weeks in the womb) is now a happy, healthy one-year-old.

Key Takeaways:

• Maisie Ransom was 16 weeks pregnant when her preborn son, Arthur, contracted parvovirus and became anemic.

• Doctors at St. George's Hospital in the UK attempted a rare procedure to treat fetal anemia, an intrauterine transfusion, normally attempted no earlier than 18 weeks.

• Fewer than 200 of the procedures are carried out each year by the National Health Service.

• According to People, IUT is one of the "riskiest, most complex and rarest lifesaving transfusions."

• Arthur is now a year old and is doing well, living with his family.

The Details:

According to a press release issued by NHS Blood and Transplant (NHSBT) on Thursday, April 21, Maisie Ransom was 16 weeks into her pregnancy with her son Arthur when he contracted parvovirus, resulting in severe anemia. 

Parvovirus, typically alluded to as “slapped cheek syndrome,” typically affects children and is characterized by a distinctive facial rash, according to the Mayo Clinic. It may also give rise to  symptoms such as fever, nausea, headaches, a runny nose, and diarrhea.

Although the infection is generally mild, it can pose significant risks to preborn and newborn babies—like Arthur, who contracted it from his mother—because their immune systems are not yet fully developed.

Medbound Times reported on Ransom's hospital, St. George's, and the doctors' decision to attempt a rare procedure:

According to NHS Blood and Transplant, Arthur developed fluid accumulation followed by heart failure in utero, prompting doctors at St George’s Hospital to carry out a rare intrauterine transfusion (IUT).

Intrauterine transfusion (IUT) is an invasive yet essential procedure used to treat severe fetal anemia, with evidence showing improved clinical outcomes.

It involves processing carefully matched donor blood into small volumes of highly concentrated red cells. These are then delivered through a needle, typically into the umbilical cord, under continuous ultrasound guidance.

As reported by People, in Arthur’s case, the transfusion was administered through the mother’s uterus into the fetus, restoring oxygen delivery. This helped the excess fluid around his heart and organs to be gradually reabsorbed, allowing normal function to resume.

As People reported, IUT is “one of the riskiest, most complex and rarest lifesaving transfusions."

Ransom expressed gratitude to those who donated to save Arthur’s life:

“The experience was absolutely terrifying. The doctor said it was 50/50 whether he would make it or not. He was so small the doctors were working within millimetres.

Without that blood he would not have made it. His organs were failing, his heart was completely enveloped in fluid and it was struggling to pump. If nothing was done he would not have made it much longer. 

The doctor said to the best of her knowledge there was no one younger to get an intrauterine transfusion. Arthur's doing great now, he's a really chirpy little boy, reaching all the milestones. He keeps us on our toes. I think every day about how lucky I am.

To have the life I am now living, with my family, there are no words to express the gratitude I feel and how fortunate I was to be able to access that care and blood promptly.

I do often wonder who the person to donate was as I would love to tell them that their decision to give blood gave my boy the chance to be here."

Dr Anne Kelly, Paediatric Transfusion and Components Clinical Expert at NHS Blood and Transplant, revealed that intrauterine transfusions are uncommon and are only performed in highly specialized centers when necessary to save a life.

As preborn recipients are exceptionally susceptible, only certain male donors are eligible to provide blood for intrauterine transfusions.

Fewer than 200 such procedures are carried out each year by the National Health Service on babies suffering from severe anemia. According to The Times, these transfusions are typically not performed before 18 weeks of pregnancy. Arthur was 16 weeks.

The Bottom Line:

Arthur Ransom’s story is one of medical courage, parental hope, and the lifesaving power of medical interventions for even preborn children.

NHS Blood and Transplant indicated that donor blood from an unknown donor was used in Arthur's life-saving transfusion, and his survival showcases the quiet heroism of blood donors.

Progress in prenatal medicine can save the lives of both mother and child in danger, and Arthur’s miraculous survival bears testament to the dignity and value of every preborn child.
