NewYork-Presbyterian/Columbia surgeons perform first 'ex vivo' lung transplants in New York
Date:12/12/2011

NEW YORK (Dec. 12, 2011) -- A 59-year-old woman from upstate New York and a 60-year-old woman from the New York metro area were the first patients in New York state and among the first in the United States to receive transplanted lungs that were assessed and reconditioned in the operating room -- a technique that has the potential to dramatically increase the availability of lungs for transplant. The experimental procedure was performed by Dr. Frank D'Ovidio at NewYork-Presbyterian Hospital/Columbia University Medical Center.

The "ex vivo" or outside-the-body approach involved removing lungs from a deceased donor, then enclosing them inside a transparent dome and connecting them to a cardiopulmonary pump and a ventilator. For four hours, the lungs were infused with nutrients and antibiotics. They were gradually warmed to body temperature, ventilated and oxygenated -- a process that resembles breathing, with the lungs inflating and deflating. Once determined to be viable, the lungs were immediately transplanted into the patients.

"Assessing lungs this way gives us a much more precise picture of how they should perform after transplant, and the reconditioning process may actually improve the chances of success," says Dr. D'Ovidio, associate surgical director of the lung transplant program at NewYork-Presbyterian Hospital/Columbia University Medical Center and assistant professor of surgery at Columbia University College of Physicians and Surgeons.

Traditionally, transplant surgeons have relied on a less sophisticated assessment. "Now with the ex vivo method, not only can we see the lungs inflate and deflate, but we also get hard data on how they function by monitoring multiple parameters and ultimately making sure that the gas exchange is happening at the level it needs to," continues Dr. D'Ovidio.

Going forward, the ex vivo procedure could significantly increase the availability of donor lungs, says Dr. D'Ovidio. "This has th
