Ever get a paper cut or nick yourself while shaving? When that happens, a blood clot saves the day. It quickly stops the bleeding, and when it’s done its job, it usually breaks up. Sometimes, though, things can go wrong.

When blood clots don’t fall apart, they can be dangerous and lead to serious medical conditions. You can get them in blood vessels in just about any part of your body. They’re most likely to affect a leg, especially if you sit for long periods of time.

You might get a clot in your arteries, which carry oxygen in your blood from your heart to all the cells of your body. The result can be really serious. It can keep oxygen from getting to your heart, lungs, or brain, and cause a life-threatening emergency, like a heart attack or stroke.

You could also get a clot in the veins that carry blood back to your heart. When that happens, symptoms usually come on more gradually, but can still mean trouble.

If you learn the warning signs, you’re more likely to get quick medical help that can make a huge difference in keeping you out of the danger zone. But it’s important to know that in some cases, clots can happen with few symptoms or none at all..

When a blood clot forms in one of the deep veins in your arm or leg, way beneath your skin’s surface, it could be something called a deep vein thrombosis (DVT). That’s dangerous because the clot could travel to your heart or lungs.

You’re more likely to get a DVT if you haven’t moved around for a long time, say after surgery or during a long plane trip. Get medical help right away if you notice any of these symptoms:

• Swelling. This can happen in the exact spot where the blood clot forms, or your entire leg or arm could puff up.
• Change in color. You might notice that your arm or leg takes on a red or blue tinge, or gets itchy.
• Pain. As the clot gets worse, you may hurt or get sore. The feeling can range from a dull ache to intense pain. You may notice the pain throbs in your leg, belly, or even your arm.
• Warm skin. The skin around painful areas or in the arm or leg with the DVT may feel warmer than other skin.
• Trouble breathing. If this happens, it could mean that the clot has moved from your arm or leg to your lungs. You may also get a bad cough, and might even cough up blood. You may get pain in your chest or feel dizzy. Call 911 to get medical help right away.
• Lower leg cramp. If the clot is in your calf or lower leg, you may feel like you have a cramp or charley horse.
• Pitting edema. DVT can cause fluid buildup (edema) in the arms or legs. It typically happens quite quickly with DVT. When you press on the swollen area, it can cause a dimple or “pit” (pitting) that remains for a few seconds.
• Swollen, painful veins. The pain may increase with touch.

A blood clot that forms in or around your ticker may cause a heart attack. Watch out for symptoms like these:

• Severe pain in your chest and arm
• Sweating
• Trouble breathing

A blood clot in your lung usually starts out in a deep vein in your arm or leg, then breaks off and travels to your lung. When this happens, you get what’s called a pulmonary embolism, an extremely dangerous condition.

Get medical help right away if you:

• Feel short of breath or have problems breathing
• Get pain in your chest
• Start to cough
• Begin to sweat
• Feel dizzy

Blood clots here may be caused by fatty deposits in the walls of the blood vessels that bring blood to your brain. Or sometimes, they may form because of a blow to your head that leads to a concussion.

In other cases, a clot that starts out in a different part of your body, like your chest or neck, might enter your bloodstream and travel to your brain, where it can cause a stroke.

Watch out for these symptoms:

• Problems with your vision or speech
• A seizure
• General feeling of weakness

Blood clots can happen in the veins that drain blood from your intestines. They can be caused by conditions like diverticulitis or liver disease, or even by birth control pills.

How will you know if this is going on? Check with your doctor if you have problems like these:

• Nausea or vomiting
• Severe pain in your belly, which may be worse after you eat
• Diarrhea
• Bloody stools
• A bloated feeling

A blood clot in your kidneys can keep them from removing waste from your body. That can cause high blood pressure or even kidney failure.

This is dangerous, so look out for these symptoms:

• Pain in the side of your belly, legs, or thighs
• Blood in your urine
• Fever
• Nausea or vomiting
• High blood pressure
• Sudden severe leg swelling
• Trouble breathing

Deep vein thrombosis: causes, symptoms

Deep vein thrombosis (DVT) occurs due to blood clotting in the deep veins of the extremities, most commonly the large veins of the legs.
Sometimes these clots are released and travel through the veins through the heart to settle in the arteries of the lungs. This related condition is known as a pulmonary embolism (PE) and can cause severe chest pain or shortness of breath. PE can be life-threatening if the embolus (circulating clot) is large.

Causes

DVT can occur when blood pools in the deep veins of your legs, when there is some factor that makes a blood clot more likely, or when there is damage to the vein wall. The blood will clot if the flow is interrupted. This may be due to compression of the vessel.
For example, when you are bedridden (after surgery) or when you sit still for long periods (such as during a long plane flight), blood can pool in the large veins in your legs and form clots. Trauma, certain types of serious illnesses, and certain medications also increase the tendency to clot.

Symptoms

About half of people with DVT have no symptoms. These are so-called “silent” DVTs that may resolve on their own or lead to a pulmonary embolism. If symptoms do occur, they usually occur in only one leg and include:

• swelling in the lower leg, ankle, foot, or (rarely) thigh;
• slight inflammation of the affected area;
• touch sensitivity;
• pain in the calf or behind the knee;
• leg cramps at night;
• the affected skin is slightly redder than usual; a bluish tint means a serious blockade;
• pain on weight bearing;
• sharp pain in lower leg when your leg is bent up;
• slightly elevated temperature;

Who is in danger?

Deep vein thrombosis occurs in about two in 1000 people and is most common in adults over 60 years of age. Diseases and circumstances that increase the risk of developing DVT:

• obesity;
• smoking;
• pregnancy;
• use of oral contraceptives;
• cancer;
• injuries or operations on the lower extremities;
• family history of DVT;
• previous thrombosis or embolism;
• recent surgery or trauma;
• fractures of the femur or tibia;
• being bedridden or in a wheelchair;
• stroke;
• heart attack.

Diagnostics

Your doctor will review your medical history and perform a physical examination. However, more tests are needed to confirm a diagnosis of deep vein thrombosis because the symptoms are often similar to those of other conditions. Frequent diagnostic tests for DVT:

1. Doppler and vascular duplex scanning is a combination of ultrasound and a flow probe that shows the direction of blood flow in the veins. This combination will show any blockage in the veins.
2. Contrast venography involves injecting a substance into a vein that is visible on an x-ray.

Blood clots are sometimes found on a CT scan. A sample of your blood may also be sent to a laboratory to check for conditions that cause increased blood clotting.

Treatment

Treatment usually requires hospitalization and bed rest, at least initially. However, prolonged sitting in one position should be avoided. First, a combination of anticoagulant drugs is used to “thin” the blood to prevent further clotting. Regular blood tests tell your doctor when these drugs are working properly.

Your doctor will prescribe medications and monitor their effects.

Leg compression devices are often used to prevent DVT while you are in the hospital. The leg may be elevated to reduce swelling. A warm and damp bandage may be applied to the affected area to relieve pain.
In rare cases, a clot may require surgical removal.

Prophylaxis

General healthy lifestyle measures (exercise, avoiding cigarettes, and weight control) can help reduce your overall risk of developing DVT. For people who have had DVT or are at risk of developing DVT, the following preventive measures are recommended:

1. Avoid prolonged bed rest or immobility of the legs. Leg exercises help prevent ailment. Walking as soon as possible after surgery will help reduce the risk of DVT. If you are unable to exercise, your health care provider should massage your legs and perform passive exercises on them within their range of motion.
2. Ask your doctor or pharmacist about special support stockings. Make sure the stockings are snug, but not too tight in any one area, as this can block blood flow. Take them off once a day to wash them and check your skin for discoloration or irritation.
3. Keep your legs elevated when lying or sitting to help return blood to the veins in your legs.

Airline:

1. Drink plenty of (non-alcoholic) liquids while flying.
2. Raise your ankles and massage your calves regularly while you are sitting.
3. Wear loose, non-restrictive clothing.
4. Do not take sleeping pills as they will make you move less during the flight.
5. Be vigilant for symptoms of DVT for up to a month after long flights.

Deep vein thrombosis: symptoms and treatment

Modern people often face diseases of the superficial leg veins, in particular varicose veins and its complications. But deep veins are often also at risk. Unfortunately, we know much less about the features of deep vein disease and their treatment than about the same varicose veins. What to pay attention to, how thrombosis differs from thrombophlebitis and what to do when symptoms of diseases appear – we will try to figure it out.

How the venous system of the legs works

Relatively speaking, the veins on the legs form two levels – superficial and deep. Superficial veins provide only about 10% of venous blood flow, but they perform a very important function. In addition to collecting blood and moving it to the heart, these veins can play the role of a kind of reservoir, which, if necessary, can receive blood from deep veins. Thus, the load on the veins is regulated by internal mechanisms.

Veins from the deep and superficial layers are interconnected by the so-called perforating veins. Due to this, balance is maintained in the venous system.

Superficial veins are at risk of excessive stretching: if a person does not move much, does not eat well, suffers from excess weight and simply has a hereditary predisposition, then blood flow slows down and the vein wall stretches. Special valves that block the reverse flow of blood do not close tightly, and we are talking about varicose veins. Deep veins are located in the thickness of tissues and ensure the movement of the main volume of blood to the heart. The surrounding muscles maintain the tone of these vessels and facilitate blood flow, so deep veins are not susceptible to varicose veins.

Thrombophlebitis is a dangerous complication of varicose veins

Slow movement of blood through the superficial veins, as well as damage to the vascular walls (and stretching often leads to them) – these are two factors that play an important role in the formation of thrombophlebitis of the lower extremities. Symptoms of this disease are pain in the leg, redness, thickening along the vein. All this is a consequence of the formation of a thrombus, a blood clot in the lumen of a vessel. Often, a blood clot can completely close the vein. The separation of a blood clot is also dangerous, since in this case it can clog another vessel, for example, the pulmonary artery.

Thrombophlebitis is a disease of the superficial veins, which is most often a complication of varicose veins. If the disease occurs on its own, without prior expansion of the veins, the cause of this is usually disorders in the blood coagulation system. Symptoms of thrombophlebitis without varicose veins always attract the attention of doctors, and this situation requires additional examinations.

Let us emphasize once again that everything described refers to superficial veins. If we are talking about deep vein thrombophlebitis of the lower extremities, symptoms and treatment… Can we talk about this disease?

Thrombophlebitis or thrombosis?

If blood clots form in the deep veins of the lower extremities, then we are not talking about thrombophlebitis, but about thrombosis. What is the difference between these two diseases?

Thrombophlebitis is a disease that occurs mainly as a result of injury to the vein wall. It is accompanied by inflammation, which, together with a slowdown in blood flow, causes the formation of blood clots. Thrombosis of the veins of the lower extremities is a disease caused by a malfunction of the blood coagulation system. It is not associated with varicose veins, nor is it preceded by damage to the veins, although the presence of trauma increases the risk of thrombosis. And it poses no less danger to the body than thrombophlebitis, since there is a possibility of blocking the blood flow or detaching a blood clot.

Factors contributing to the development of thrombosis include:

• advanced age
• weight gain, decreased physical activity
• taking oral contraceptives
• pregnancy (during this period, a woman’s blood clotting properties may change)
• smoking
• surgical operations

Thrombosis of the lower extremities – symptoms

An additional danger of thrombosis is that the disease may not manifest itself for a sufficiently long time. Symptoms appear when the thrombus reaches a large size and spreads up the vessel. Then the patient complains of pain, which decreases at rest and increases with physical activity. Then, due to the deterioration of the outflow of blood, edema joins the pain. The skin on the leg turns pale (to cyanosis) and “stretches”, acquiring a glossy sheen.

To diagnose the localization of a thrombus, ultrasound of the veins is performed, and in especially difficult cases, angiography, X-ray examination with the introduction of a contrast agent into the vessels.

What to do?

The appearance of symptoms of deep vein thrombosis of the lower extremities suggests that the patient should immediately consult a doctor and begin treatment. The specialist will assess the location and nature of the thrombus and help prevent its separation or complete blockage of the vessel.

Common treatments include blood thinners (heparin) and compression stockings to help maintain proper venous blood flow. For several days, the patient may be recommended bed rest, while the position of the legs should be slightly elevated.
