Deep vein thromboses (DVTs) are clots in the blood system that can travel from the legs to the lungs, causing severe damage and even death. This week on Beyond the Abstract, Ellen and Derek are joined by John Welsh, PhD as they dive into John's recent paper on how DVTs are formed. To our surprise, Dr. Welsh discusses how current measures in the hospital to prevent DVTs may not work as well as we think they do. Finally, we talk about Dr. Welsh's company, which is currently building a device that would better solve this problem.Welsh et al. Hemodynamic regulation of perivalvular endothelial gene expression prevents deep vein thrombosis. Journal of Clinical Investigation, 2019. 129(12). PMID: 31710307.
