A two-year-old Korean toddler who was born with a rare congenital abnormality which prevented her trachea from fully developing, has received a cell-based artificial windpipe.
Hannah Warren is the youngest person in the world to have the surgery. Prior to the April 9 procedure, Hannah could not breathe, eat, drink, or swallow on her own and had spent her entire life in a Seoul, South Korea hospital.
The transplant was of a tissue-engineered, bioartificial trachea, that was made with non-absorbable nanofibers and stem cells from Hannah's own bone marrow. Because no organ donors were used and the tissue came from Hannah herself, the chance of her immune system rejecting the transplant is virtually nonexistant.
Doctors said Hannah is recovering and is likely to lead a normal life.
