WEDNESDAY, Dec. 4, 2013 (HealthDay News) -- The blood vessels in
face transplant patients reorganize themselves after the procedure,
During a full face transplant, the recipient's major arteries
and veins are connected to those in the donor face to ensure
healthy circulation. Because the procedure is new, not much was
known about the blood vessel changes that occur to help blood make
its way into the transplanted tissue.
The development of new blood vessel networks in transplanted
tissue is vital to face transplant surgery success, the
investigators pointed out in a news release from the Radiological
Society of North America (RSNA).
The researchers analyzed blood vessels in three face transplant
patients one year after they had the procedure at Brigham and
Women's Hospital in Boston. All three had excellent blood flow in
the transplanted tissue, the team found.
"We assumed that the arterial blood supply and venous blood return was simply from the connections of the arteries and the veins at the time of the surgery," study co-author Dr. Frank Rybicki, director of the hospital's Applied Imaging Science Laboratory, said in the news release.
It turns out this is not the case, the researchers noted.
"The key finding of this study is that, after full face transplantation, there is a consistent, extensive vascular reorganization that works in concert with the larger vessels that are connected at the time of surgery," study co-author Dr. Kanako Kumamaru, a research fellow in the laboratory, said in the news release.
The study was scheduled for presentation Wednesday at the RSNA's
annual meeting, in Chicago. Data and conclusions should be viewed
as preliminary until published in a peer-reviewed journal.
