UC Health performs first liver transplant in US using mobile cold perfusion pump

Posted by:

Transplant surgeons at UC Health’s University of Cincinnati (UC) Medical Center have performed the first-ever liver transplant in the United States with an organ preserved using portable hypothermic machine perfusion. The technology, which had been under development for several years, is designed to circulate a specially formulated, cold-temperature medical solution throughout a donor liver during its journey from the point of donation to surgical transplantation into a recipient.

This “active” preservation device was invented to improve upon traditional “static” cold preservation, ...

Keeping donated livers warm could improve transplants

Posted by:

Surgeons pack donated organs on ice while racing them to transplant patients but it may be time for a warmer approach. British researchers said Wednesday that keeping at least some livers at body temperature instead may work better.

The livers keep functioning until they’re transplanted thanks to a machine that pumps them full of blood and nutrients. It’s a life-support system for the organs and similar machines are being explored for lung and heart transplants, too.

The transplant community isn’t ditching affordable ...

Could donor organs be frozen to save lives later?

Posted by:

Long-term preservation of donor organs and tissue for on-demand transplants and medical procedures sounds futuristic — something of the medical ideal.

Need a heart or kidney transplant? Just grab one from the freezer. But, hey, the Arctic wood frog thaws and reanimates each year after being frozen for 240 days, so why can’t the same be done for human hearts, lungs and livers?

Such research, long underway with success in preserving skin tissue and heart valves, largely has remained off the radar, ...

New method rescues donor organs to save lives

Posted by:

Researchers have — for the first time — maintained a fully functional lung outside the body for several days. They designed the cross-circulation platform that maintained the viability and function of the donor lung and the stability of the recipient over 36-56 hours, used the advanced support system to fully recover the functionality of lungs injured by ischemia and made them suitable for transplant.

Will We Be Able to Cryogenically Freeze Organs One Day?

Posted by:

A milestone in cryobiology announced this week is literally heart-warming.

A new nanoparticle technology warmed cryopreserved heart valves and blood vessels without damaging the tissues, found a study published Wednesday in the journal Science Translational Medicine. According to the researchers, this means that cryopreserving human hearts and kidneys in organ banks — and making them available for later use in patients — is finally within sight.

“We are not in any way declaring victory here,” said John Bischof, senior author of the ...

In Organ Transplants, Cooling Things Down May Not Be The Way To Go

Posted by:

Last year, tens of thousands of organs were removed from dead or dying patients, packed in ice, and raced to an operating room so a very sick patient could get a life-saving transplant. On average, 22 people die every day in the U.S. because they couldn’t get one of those organs. Now, a company and hospital in Massachusetts are teaming up to figure out if there might be a better way to do those transplants, and to save more lives.

Biology ...
