Doctors in Japan announced on Thursday they have successfully performed the world’s first transplant of lung tissue from living donors to a patient with severe lung damage from COVID-19.
The recipient, identified only as a woman from Japan's western region of Kansai, is recovering after the nearly 11-hour operation on Wednesday, Kyoto University Hospital said in a statement. It said her husband and son, who donated parts of their lungs, are also in stable condition.
The university said it was the world's first transplant of lung tissue from living donors to a person with COVID-19 lung damage. Transplants from brain-dead donors in Japan are still rare, and living donors are considered a more realistic option for patients.
"We demonstrated that we now have an option of lung transplants (from living donors)," Dr Hiroshi Date, a thoracic surgeon at the hospital who led the operation, said at a news conference. "I think this is a treatment that gives hope for patients" with severe lung damage from COVID-19, he said.
Kyoto University said dozens of transplants of parts of lungs taken from brain-dead donors to patients with COVID-19-related lung damage have been carried out in the United States, Europe and China.
The woman contracted COVID-19 late last year and developed breathing difficulties that rapidly worsened. She was placed on a life support machine that works as an artificial lung for more than three months at another hospital because her lungs were so severely damaged.
Even after she was free of the virus, her lungs were no longer functional or treatable, and the only option for her to live was to receive a lung transplant, the university said.
Her husband and son volunteered to donate parts of their lungs, and the surgery was conducted at Kyoto University Hospital by a 30-member team headed by Dr Date. Her husband donated part of his left lung, and son gave part of his right lung.
She is expected to be able to leave the hospital in about two months and return to her normal life in about three months, the university said.
It is the latest grim milestone after the novel coronavirus surfaced in central China in December 2019 and went on to infect more than 139 million people, leaving billions more under crippling lockdowns and ravaging the global economy.
The surge in deaths and number of corona patients also indicate the looming danger, said a research done by Geo News, which is based on experts’ comments and analysis of data collected from four big cities of the country.
"Lots of new cases of COVID-19 infections in children are coming in this second wave and the numbers are much, much higher than they were earlier," Dr Krishan Chugh, head of the department of paediatrics at Fortis Memorial Research Institute, Gurgaon, said.
