WEDNESDAY, Nov. 23 (HealthDay News) -- A 36-year-old husband and father of two children with an inoperable tumor in his trachea (windpipe) has received the world's first artificial trachea made with stem cells.
A report published online Nov. 23 in The Lancet described the transplant surgery, which was performed in June at the Karolinska University Hospital in Stockholm, Sweden.
Without the transplant, the authors of the report explained, the man from Reykjavik, Iceland would have died. A golf ball-sized tumor on his trachea had begun to restrict his breathing. In a 12-hour procedure, doctors completely removed the affected area of his trachea and replaced it with an artificial one.
The artificial trachea was custom-made using three-dimensional imaging. First, a glass model was built to help shape an artificial scaffold. Stem cells were then inserted into the scaffold to create a functioning airway, the authors explained in a journal news release.
The scientists said their technique is an improvement over other methods because they used the patient's own cells to create the airway so there is no risk of rejection and the patient does not have to take immunosuppressive drugs.
In addition, they noted, because the trachea was custom-made it would be an ideal fit for the patient's body size and shape, and would eliminate the need to remain on a waiting list for a human donor.
"The patient has been doing great for the last four months and has been able to live a normal life. After arriving in Iceland at the start of July, he was one month in hospital and another month in a rehabilitation center," a co-author of the study and the physician who referred the patient for the procedure, Tomas Gudbjartsson, of Landspitali University Hospital and University of Iceland, Reykjavik, said in the news release.
The transplant team has since performed another transplant on a second patient from Maryland
