What are the clincal differences between arterial and venous thrombosis?
Blood clots in the veins is venous, clots in the arteries is arterial.Blood clots in the deep vein, that is your big one that runs through your body is called Deep Vein Thrombosis and those are the serious ones that can go to your heart or lungs and sometimes kill you. Blood clot in the Arterial Veins are in the little veins that run through your body and they can hurt just as much and need to be treated also, but they can not break off and go to your heart or lungs. I have had both.

venous thrombosis
Cerebral veins contain about 70 per cent of the total cerebral blood volume, but cerebral venous thrombosis (CVT) occurs about a thousand times less often than arterial stroke. CVT affects mostly young adults and children, and in about one quarter of cases the cause remains unknown. Written by international experts, this publication is dealing with epidemiology, risk factors, coagulation disorders, clinical presentation - especially focusing on headache, current neuroradiological treatment, comp

Deep Vein (Venous) Thrombosis (DVT) and Pulmonary Embolism (PE) - 3D Medical Animation
This 3D medical animation depicting Deep Vein Thrombosis (DVT or Deep Venous Thrombosis) begins by showing a blood clot forming in a lower leg vein. As red blood cells flow through the vein, slower moving cells and other blood elements accumulate on the venous valves, creating a stationary blood clot, or thrombus, blocking the blood flow in the vein. When the thrombus breaks free of the valve leaflet, it is then called an embolus, and travels toward the heart and lungs. The last section of the animation shows the embolus lodging in the lung tissue to form a life-threatening pulmonary embolism. Item #ANC00001

DVT or deep vein thrombosis happens because of a blood clot forming in the vein, normally in the pelvis or legs. The condition of DVT can also be known by the terms of thrombophlebitis, phlebothrombosis, or venous embolism. This condition occurs more often in people who have just undergone pelvic, thoracic, abdominal or orthopedic surgery. People suffering from cancer, heart disease, had a heart attack recently, or afflicted with other serious diseases have a higher susceptibility for getting DVT.
The episodes of DVT can be serious and reoccur. There are some contributing factors for DVT and they are such things as: the makeup of the blood changes to clot faster, drastic alterations in how the blood is able to flow, and the lining of the vessels carrying the blood get damaged (high blood pressure can be a cause of this). Deep vein thrombosis happens due to blood clots being in the vessels that carry the blood, these clots form in the vessels where the flow of blood has been restricted. DVT usually happens in areas of deep veins in the pelvic or leg areas which have been damaged or weakened. In certain cases deep vein thrombosis can show up in an arm in the area of the shoulder, this is called Paget-Schrötter disease.
The symptoms that are the most noticeable for deep vein thrombosis are pain, redness, and swelling of the limb it is in. In certain instances, the veins that are visible at the skin's surface could be swollen. Symptoms that are external like this only happen in less than 50% of the people who have this condition. This disease can be so dangerous due to it being silent so often. It is recommended that anyone with a history of DVT in their family should be checked regularly for it.
The signs for pulmonary embolism, which can be a deadly side effect of deep vein thrombosis, are coughing blood up, fainting, dizziness, chest pains made more intense with breathing deep or coughing, rapid breathing along with an increase in pulse, and shortness of breath. Anyone having these signs needs to search out medical help immediately, especially when there is a medical history for DVT with them or in their family.
Deep vein thrombosis is often treated with certain drugs depending on its severity. Bed rest is recommended along with elevating the legs to improve the condition. Compression stockings (gradient elastic stockings) may have to be put on the legs each day for as long as one year. It will also be recommended that the person not stand or sit for long time periods.
Drug therapy is highly used to lower the possibility for blood clots in DVT. Usually blood thinners are the drugs that are used to prevent blood clots from forming. Heparin is one of the popular anticoagulant that is given through injections, and is combined with Coumadin. This treatment is normally given for about 3 months.
People suffering with a serious case of DVT could get thrombolytic therapy in an attempt to break down the blood clots. An example of this is tissue plasminogen activator. Thrombolytics ups the chance of severe bleeding though; this should just be used in the event the person's thrombosis is endangering their life.
Another method of preventing the clots getting to the lungs or heart is to take a filter and insert it in the person's vena cava. These are usually used for the patients that have a hard time with the anticoagulant drugs or simply can't take them. They are also used in patients who have a higher chance of falling or have more than one trauma they are dealing with. When people don't respond effectively to the drug therapy a filter may need to be used.
Those people who have a higher chance of DVT should lose weight; do regular exercise (with emphasis on the legs, and quit smoking to help lower their risk. Those people who have to sit or fly for long durations need to make sure to walk and stretch every few hours for a brief time. While traveling they need to drink enough water. They need to keep their blood flowing, most importantly in their legs.
DVT has to be treated because it is life threatening. Anyone, especially someone who has a family history of DVT, who suffers symptoms of the deep vein thrombosis, should seek out medical treatment immediately.
