Thrombosis [edit on Wikidata] Thrombosis (Greek: θρόμβωσις) is the formation of a blood clot (thrombus; Greek: θρόμβος) inside a blood vessel, obstructing the flow of blood through the circulatory system. When a blood vessel is injured, the body uses platelets (thrombocytes) and fibrin to form a blood clot to prevent blood loss.

Overview Deep vein thrombosis (DVT) is a blood clot in one of the deep veins in the body. Blood clots that develop in a vein are also known as venous thrombosis. DVT usually occurs in a deep leg vein, a larger vein that runs through the muscles of the calf and the thigh.eep vein thrombosis (DVT) is a blood clot in one of the deep veins in the body.

Deep Vein Thrombosis  (DVT) Deep vein thrombosis (throm-BO-sis), or DVT, is a blood clot that forms in a vein deep in the body. Blood clots occur when blood thickens and clumps together. Most deep vein blood clots occur in the lower leg or thigh. They also can occur in other parts of the body.A blood clot in a deep vein can break off and travel through the bloodstream. The loose clot is called an embolus (EM-bo-lus).It can travel to an artery in the lungs and block blood flow.This condition is called pulmonary embolism (PULL-mun-ary EM-bo-lizm), or PE. blood clot in a deep vein can break off and travel through the bloodstream.

Overview Deep venous thrombosis (DVT) is the presence of coagulated blood, a thrombus, in one of the deep venous conduits that return blood to the heart. The clinical conundrum is that symptoms (pain and swelling) are often nonspecific or absent.

- A blood clot is an organized clump of hardened blood. Normal blood clotting helps stop blood loss, such as when you get a minor cut or scrape. However, a blood clot that forms inside a blood vessel (artery or vein) or in the heart is called a thrombus and is a serious medical condition. Blood clots can form in the superficial veins just below your skin, or they can form in the deeper, large veins (deep vein thrombosis).

Thrombosis Even when a blood vessel is not injured, blood clots may form in the body under certain conditions. A clot, or a piece of the clot, that breaks free and begins to travel around the body is known as an embolus. Thrombosis may occur in veins (venous thrombosis) or in arteries. Venous thrombosis leads to congestion of the affected part of the body, while arterial thrombosis (and rarely severe venous thrombosis) affects the blood supply and leads to damage of the tissue supplied by that artery (ischemia and necrosis).

- Deep vein thrombosis (also called DVT) is a blood clot in a vein deep inside your body. These clots usually occur in your leg veins.While DVT is a fairly common condition, it is also a dangerous one. If the blood clot breaks away and travels through your bloodstream, it could block a blood vessel in your lungs.This blockage (called a pulmonary embolism) can be fatal.eep vein thrombosis (also called DVT) is a blood clot in a vein deep inside your body.

Venous Blood Clots (Thrombi, DVT) When a blood clot forms and stays where it forms, it’s called a thrombus. A thrombus that breaks loose or travels from where it formed and goes to another location in the body is called an embolus. Sometimes a piece of plaque, small pieces of tumor, fat globules, air or amniotic fluid can act like an embolus – breaking loose and traveling somewhere to block off blood flow.

Thrombosis Thrombosis usually begins as an inflammation of the vein known as phlebitis * . Phlebitis develops when blood flows slowly or pools in veins. This usually occurs in the legs and causes injury to the walls of the vein.Just as platelets gather to form clots on cut fingers, they also may start to form clots along the injured walls of veins.he biggest danger is when a clot forms in the large veins that are deep within the legs. If the blood clot grows, it may break off. The clot may then travel toward and then through the heart and block the pul-monary * artery, which is a major blood vessel, causing a pulmonary embolism * .

Coronary Thrombosis â Causes, Symptoms and Treatment The term coronary thrombosis and myocardial infarction, or heart attack, is often used interchangeably. Coronary thrombosis is a condition that leads to heart attack, however, and not the heart attack that occurs after a blood clot develops in the arteries. A coronary occlusion, or thrombosis, occurs when a blood clot causes a blockage leading to the heart. According to the Center for Disease Control, over 700,000 people have a heart attack each year. Of that number, about 15% of people will experience a fatal heart attack.

Thrombus A thrombus, or colloquially a blood clot, is the final product of the blood coagulation step in hemostasis. There are two components to a thrombus: aggregated platelets that form a platelet plug, and a mesh of cross-linked fibrin protein.he substance making up a thrombus is sometimes called cruor. A thrombus is a healthy response to injury intended to prevent bleeding, but can be harmful in thrombosis, when clots obstruct blood flow through healthy blood vessels. Mural thrombi are thrombi that adhere to the wall of a blood vessel.

- Deep Vein Thrombosis - Topic Overview. Deep vein thrombosis (DVT) is a blood clot (thrombus) in a deep vein, usually in the legs. Clots can form in superficial veins and in deep veins. Blood clots with inflammation in superficial veins (called superficial thrombophlebitis or phlebitis) rarely cause serious problems.

Deep Vein Thrombosis (DVT) Deep vein thrombosis (DVT) is a serious condition that occurs when a blood clot forms in a vein located deep inside your body. A blood clot is a clump of blood that is in a gelatinous, solid state. Deep vein blood clots typically form in your thigh or lower leg, but they can also develop in other areas of your body. Other names for this condition include thromboembolism, post-thrombotic syndrome, and post-phlebitic syndrome.

It most commonly affects leg veins, such as the femoral vein. Three factors are important in the formation of a blood clot within a deep vein—these are the rate of blood flow, the thickness of the blood and qualities of the vessel wall.
