Joseph B. Shrager, professor of cardiothoracic surgery at the Stanford University Medical Center, speaks about new surgical treatments for emphysema that could dramatically improve symptoms and, in many cases, increase longevity. Current medical treatments of emphysema provide a modest degree of palliation, but there is no medical therapy that dramatically improves emphysema patients' shortness of breath or improves their survival. The new surgical treatments that Dr. Shrager shares could completely change the way emphysema is treated.
