With DVT, blood clots form in the large veins deep within the legs, pelvis, and sometimes in the arms. DVT strikes about 1 in 20 people over the course of a lifetime.
When a blood clot breaks free from a deep vein and makes its way into an artery in the lung, it is called a pulmonary embolism PE. PE is life-threatening condition that can cause heart failure. It is important to call if you have trouble breathing or if you are coughing up blood. In this condition, the symptoms of pain, heaviness in the leg or foot, cramps; itching; tingling; bluish or brownish, flaky skin; sores; and varicose veins caused by DVT continue after treatment, either because the blood clot is still there or the blood clot caused other damage to the vein.
CVI is damage or weakness in the vein wall or vein valve that allows blood to flow back into the vein venous reflux. The backflow of blood accumulates in the veins and causes inflammation phlebitis and more clotting. Clotting can block or slow blood flow through the vein raising the blood pressure and possibly causing more damage. Varicose and spider veins are caused by the accumulation of the blood from venous reflux. When pressure in the veins continues for a long time, it can break down healthy tissue, which causes ulcers or sores.
This is a catch-all term for the very few people, less than 1 percent, who are born with veins that are defective in some way. For example, the veins may not have valves. This category also includes birthmarks that are a cluster of veins close to the skin. This research is both literally and figuratively "close to the heart" for Farquhar.
He said he has always had an interest in cardiology and helping people. Before his UD career, he worked with cardiac patients in a rehabilitation setting, where he provided patients with information about the risk factors affecting heart disease and the benefits of exercise. Then, during his postdoctoral training at Boston's Beth Israel Deaconess Medical Center, he worked with patients who were unable to stand without getting dizzy. And that began his research on veins.
Today, he's busy working to find out what role these less-studied blood vessels may play in high blood pressure. Materials provided by University Of Delaware.

Sometimes it becomes too simple to get caught up in the doing. To lose sight of the why behind it all.
Reading your Bible and praying, going out of your way to show kindness to someone in need — these are truly good things. Lying, stealing, lusting — these truly are evil. There is, however, so much more to it than this surface knowledge and even than acting on this knowledge.
For love! Toma discovered why Christ bled on the cross. It was not for Christianity or orthodoxy or any religion. Christ bled on that cross for us. And how much did He give? Just enough to satisfy the requirement, to fulfill a covenant or agreement? Let us know in the comments! Save my name, email, and website in this browser for the next time I comment.
