The nation's first full face transplant patients are growing into their new appearances — literally.
Medical
imaging shows new blood vessel networks have formed, connecting transplanted
skin with the patients' facial tissue, a finding that may help improve future
face transplant surgeries, doctors announced Wednesday.
Dallas Wiens, the first U.S. man to get a full face transplant, is a remarkable
example of that success. The 28-year-old Fort Worth man attended Wednesday's
annual meeting of the Radiological Society of North America with his new wife
and golden retriever guide dog.
Despite still visible facial scars from the
March 2011 surgery, he looks and sounds like a recovered man.
"My entire life is a miracle," Wiens said at a news conference.
His face was burned off in a 2008 painting accident at his church. He was on a
cherry-picker lift when his head hit a high voltage wire.
After surgery, Wiens lived for two years with no facial features and just a
two-inch slit for a mouth, until his transplant at Boston's Brigham and Women's
Hospital.
Imaging studies on Wiens and two other full face transplants done at Brigham in
2011 show that a network of new blood vessels had formed just a year after the
operations. A fourth full face transplant was performed at Brigham earlier this
year.
The same thing typically happens with other transplants and it helps ensure
their success by boosting blood flow to the donor tissue. But Brigham doctors
say this is the first time it has happened with full face transplants.
The finding could eventually shorten the operating time for future face
transplants, Brigham radiologist Dr. Frank Rybicki said. The operations can
take up to 30 hours and include attaching spaghetti-thin arteries in the
patients' existing tissue to the donor face, but the findings suggest attaching
only two facial or neck arteries instead of several is sufficient, he said.
Dr. Samir Mardini, a Mayo Clinic expert in reconstructive transplant surgery,
said blood vessel reorganization occurs with other types of tissue transplants
— doctors call it "neovascularization" and it helps ensure the
tissue's survival by improving blood flow.
"It's interesting that they've shown it" with face transplants, but
it's not a surprise, Mardini said.
Face transplants, using cadaver donors, are still experimental. Fewer than 30
have been done since the first in 2005, said Dr. Branko Bojovich, a surgeon
involved in a 2012 face transplant at the University of Maryland Medical
Center.
He called the Boston team's findings "very reassuring" for surgeons
and for future patients.
"We're assuming that these patients will hopefully go on to live
productive and long lives," Bojovich said.
Wiens' life before the accident was troubled, and he says he misses nothing
about it except possibly his eyesight.
"I've learned more about other people and myself, being blind," he
said.
He met his wife, Jamie Nash, in a support group for burn patients, and they
were married in March at the same church where Wiens' accident occurred. That
was a symbolic choice, Wiens said.
"The most life-changing experience I had happened at that church. I felt
like the beginning of my new life should happen there," he said.
Nash, 30, had suffered severe burns in a 2010 car crash in which she lost
control of her car while texting.
The couple lives with his 6-year-old daughter and her two children. Nash helps
him "see" and he helps her do things that are difficult because of
her scarred, stiff arms.
Together, they work with a foundation Nash set up to advocate against texting
and driving, visiting schools to bring the message to teens. Wiens says the
work helps make his new life fulfilling.
"Our life is incredible," Nash said Wednesday. "We are so
much in love."
Added Wiens, "There is life after tragedy."
