If blood clots in someones brain isn't caused from their heart, what else would it be linked to medically?

Answer 1

I'm assuming you mean someone had a stroke caused by a blood clot (ischemic stroke) as opposed to a bleeding stroke (heamorrhagic stroke)...

Blood clots inside arteries are caused by a variety of things. Blood is constantly in balance between clotting itself and thinning itself. When the balance is met things are good. When it tips in eitehr direction, you can bleed out, or have clots form. Once clots form, the tend to get "caught" in the narrowest passageway. Depending on where that artery is, different symptoms can occur. If its the head you get a stroke, if its the foot you get blue toes etc...

Clots can form on the "right side" or venous circulation (DVT). But for them to get to theleft side (systemic circulation) you need a hole in the heart to pass through. Otherwise they get filtered by the lung.

Clots that form on the left side (arterial in origin) can be form a variety of reasons. Most common is atrial fibrillation, an irregular beating of the heart. Others can be from valvular diseases such as mitral stenosis or incompetent mitral valve prolapse. They can also occur if there isinfection of the heart (endocarditis).

Clots can also form right at the site of blockage too. This is usually associated with diabetes, high blood pressure, cholesterol and smoking. Finally age is he biggest risk factor (over 70yrs).

Hypercoagulability (propensity to clot more) can be caused by genetic factors (factor V deficiency, protein C or S deficiency), carrying the lupus anticoagulant gene (usually associated with repeated miscarriages). Certain drugs can cause this. Birth control pills or injections, combined with smoking is a bad combination.

And the worst drug of all.... smoking. Usually this is the root of all things medical.

Hope that helps.

Answer 2

I am so sorry to hear about your brother. I hope he gets well soon. I also understand that sometimes when talking to doctors, they talk in a language that only another doctor can understand. You are doing the right thing by looking for information, so that you will better understand your brothers condition. I'll do my best to help you. To answer your first question. What causes blood clots? Blood Clots or Hypercoagulation is caused by proteins in your body that are supposed to keep your blood from clotting too much. some people don't make enough of these proteins. In other people, these proteins aren't doing their job properly. Or a person may have an extra protein in their blood that causes too much clotting. Hypercoagulation has a few other causes, but those causes are rare. Some people are born with a tendency to develop clots. This tendency is inherited (comes from your parents). Certain situations or risk factors can make it easier for your blood to clot too much. These situations include the following: Sitting on an airplane or in a car for a long time Having prolonged bed rest (several days at a time) Having surgery Having cancer Being pregnant Using birth control pills Your other question...Can they kill someone? A blood clot becomes harmful when it blocks an artery or vein and stops blood flow. The blood clot is then called a thrombus. Although a thrombus may occur in any blood vessel, it most commonly develops in the veins of the leg and can travel through the major blood vessels of the pelvis and lung where it can be fatal. A thrombus in the leg or pelvic vein is called a deep vein thrombosis (DVT). A thrombus that breaks free and travels through the bloodstream it is called an embolus. As it travels, it compromises blood flow and may become lodged in a smaller blood vessel, causing blockage. For example, if an embolus blocks an artery in the lung, it is called a pulmonary embolism (it sounds like this is what happened to your brother). Your brother is in the BEST place right now, the Hospital for his care. The doctor will probably pur your brother on Heparin, which is often administered for the first few days of anti-coagulant treatment since warfarin takes several days to begin working. For example, if blood clots are found in the legs or lungs, the patient will typically remain in the hospital for a few days and receive heparin to “thin” the blood. Once the risk of clotting has been decreased with heparin, the patient will stop receiving this drug, and warfarin (pill form) will be prescribed to keep the blood “thin”. I will pray for your brothers recovery. As with any condition, it is always best to talk with a doctor in addition to doing research. I will provide some websites that might help you understand more about what is happening with your brother right now. God Bless You!

Blood clots don't come from the "heart" so not sure what you mean by that. They can form anywhere and that is why some folks take anticoagulants like coumadin. After a patient has surgery and is immobile they can develop a clot that lands in the lungs and is called a pulmonary embolism. Even folks that have been sitting for long periods can throw clots. A clot that does land in the brain causes a stroke.

Answer 4

If you have a blood clot anywhere in your body, it could dislodge and travel to your brain and lodge in a vessel there. Say you have a deep vein thrombosis, or DVT in your leg, it dislodges and somehow makes it through the heart and lungs without killing you, it will then make it to your brain. The vessels of the brain are much smaller, as you might imagine, and even the smallest clot can cause a stroke.

Answer 5

It could be caused by diseases that cause your red/white cells to die, then one could get caught in a narrow space in possibly the capillaries or w/e, then it will cause a chain of effects. Like one cell gets caught, then another, then another, until that spot is totally blocked, then you'd have to get a very complicated operation or w/e. Well, that's what I think Or another of my "theories" is this... Well your brain, heart, lungs, etc are made of tissues, which are made from a group of cells(building blocks of life), so since your inside organs were originally made from cells, a small chunk could've broken off and caused clots or clogged veins/arteries (idk, it's just a thought).

Answer 6

Clots can often come from the lungs or from the legs (Deep Vein Thrombosis)..;

Answer 7

THAT CLOT COULD HAVE FORMED SOMEWHERE IN ONE OF THE MAIN ARTERIES,AND FLOATED UP THAT WAY

Answer 8

clots can come from anywhere.
