Surgeons in Chicago have performed the first known lung transplant to a coronavirus patient in the US.

Northwestern Medicine on Thursday released details of the procedure, which took place last Friday. Only a few other Covid-19 survivors, in China and Europe, have received lung transplants.

The Chicago patient, a young woman in her 20s, was on a ventilator and heart-lung machine for almost two months before her operation at Northwestern Memorial Hospital.

The 10-hour procedure was challenging because the virus had left her lungs full of holes and almost fused to the chest wall, said Dr. Ankit Bharat, who performed the operation.

She remains on a ventilator while her body heals but is well enough to speak with family members via videocall, and doctors say her chances for a normal life are good.

“We are anticipating that she will have a full recovery,” said Dr. Rade Tomic, medical director of the hospital’s lung transplant program.

The patient was not identified but Bharat said she had recently moved to Chicago from North Carolina to be with her boyfriend.

Despite being relatively healthy, the woman’s condition rapidly deteriorated after she was hospitalised in late April. Doctors waited six weeks for her body to clear of the virus before considering a transplant.

Lungs accounted for just 7 per cent of the nearly 40,000 U.S. organ transplants last year. They are typically hard to find and patients often wait weeks on the transplant list.

The Chicago patient was fast-tracked on the waiting list after doctors observed signs that her heart, kidneys and liver were beginning to fail, Bharat said.
