Talbot, RVT, FSVU, the first vascular technologist to discover the technique and application of venous imaging, this lecture begins with a review of the pathophysiology and mechanisms of venous disease. By understanding the factors contributing to the formation of venous thrombosis and embolus, characterization of acute and chronic thrombus becomes much easier. A review of venous anatomy includes microscopic anatomy and upper and lower venous vessels, and veins of the thorax, abdomen and pelvis. Venous protocols, vein mapping technique and diagnostic criteria is discussed. Module length: Core concepts 1 hours 15 minutes plus 57 minutes customized review.
