Chronic venous insufficiency occurs when your leg veins don't allow blood to flow back up to your heart. Normally, the valves in your veins make sure that blood flows toward your heart. But when these valves don't work well, blood can also flow backwards. This can cause blood to collect (pool) in your legs.

What causes defective valves in veins?

The most common cause is hereditary weak valves. The microscopic make-up of the valves is abnormal in people who have parents with vein problems. These weak valves give way, causing venous insufficiency. Female hormones, especially progesterone, cause the valve tissue to soften and give way.

What are some leg vein diseases?

What are venous diseases?Blood clots. ... Deep vein thrombosis. ... Superficial venous thrombosis or phlebitis. ... Chronic venous insufficiency. ... Varicose and spider veins. ... Ulcers.

What are the valves in your legs called?

Femoral veins typically have between one to six valves and popliteal veins often contain between zero to four valves. Valves in veins are bicuspid, meaning they have two flap-like structures that regulate blood flow. These flaps are made of elastic tissue.

What is vein disease called?

Thrombophlebitis is the inflammation of a vein (usually in an extremity, especially one of the legs) that occurs in response to a blood clot in the vessel. When it occurs in a vein near the surface of the skin, it is known as superficial thrombophlebitis, a minor disorder commonly identified by a red, tender vein.

What is DVT in leg?

DVT (deep vein thrombosis) is a blood clot in a vein, usually the leg. DVT can be dangerous. Get medical help as soon as possible if you think you have DVT.

What is the function of the valves in veins in the legs?

The one-way valves in deep veins prevent blood from flowing backward, and the muscles surrounding the deep veins compress them, helping force the blood toward the heart, just as squeezing a toothpaste tube ejects toothpaste.

What is the cause of thrombophlebitis?

The cause of thrombophlebitis is a blood clot, which can form in your blood as a result of: An injury to a vein. An inherited blood-clotting disorder. Being immobile for long periods, such as during an injury or a hospital stay.

What might be a symptom of a person whose vein valves?

When the valves do not work properly, blood will flow back into the veins instead of forward to the heart. This causes blood to pool in the veins, often in the legs and feet. This results in many of the symptoms associated with venous insufficiency, such as skin discoloration, swelling, and pain.

What is vasculitis of the legs?

Overview. Vasculitis involves inflammation of the blood vessels. The inflammation can cause the walls of the blood vessels to thicken, which reduces the width of the passageway through the vessel. If blood flow is restricted, it can result in organ and tissue damage.

What is Thurner syndrome?

May-Thurner syndrome is a rare vascular condition that affects a vein in your pelvis. It occurs when a nearby artery compresses the left iliac vein. This vein brings blood from your pelvis and legs back up to your heart. The compression prevents blood from flowing properly, leading to narrowing and scarring.

What diseases cause varicose veins?

Any condition that puts excessive pressure on the legs or abdomen can lead to varicose veins. The most common pressure inducers are pregnancy, obesity, and standing for long periods. Chronic constipation and -- in rare cases, tumors -- also can cause varicose veins.

What is vascular disease in the legs?

Peripheral artery disease (also called peripheral arterial disease) is a common condition in which narrowed arteries reduce blood flow to the arms or legs. In peripheral artery disease (PAD), the legs or arms — usually the legs — don't receive enough blood flow to keep up with demand.

What does phlebitis of the leg look like?

There is usually a slow onset of a tender red area along the superficial veins on the skin. A long, thin red area may be seen as the inflammation follows a superficial vein. This area may feel hard, warm, and tender. The skin around the vein may be itchy and swollen.

What is the most serious complication of venous insufficiency?

Left untreated, these damaged veins can cause serious complications, such as ulcers, bleeding, and a potentially fatal condition called deep vein thrombosis.

To return blood to your heart, the veins in your legs must work against gravity. Varicose veins may be caused by weakened valves (incompetent valves) within the veins that allow blood to pool in your veins instead of traveling to your heart.

How to stop varicose veins from getting worse?

Self-care — such as exercise, elevating your legs or wearing compression stockings — can help you ease the pain of varicose veins and may prevent them from getting worse. But if you're concerned about how your veins look and feel and self-care measures haven't stopped your condition from getting worse, see your doctor.

How do you know if you have varicose veins?

Signs you may have varicose veins include: Veins that appear twisted and bulging; they are often like cords on your legs.

What are spider veins?

Spider veins. Spider veins appear as thin, red lines or as weblike networks of blood vessels on the surface of the skin. Spider veins, a mild form of varicose veins, typically appear on the legs and feet. Varicose veins are twisted, enlarged veins.

Why do veins twist?

Tiny valves in your veins open as blood flows toward your heart then close to stop blood from flowing backward. If these valves are weak or damaged, blood can flow backward and pool in the vein, causing the veins to stretch or twist.

How to treat leg pain from veins?

To reduce the risk factors for developing blood clots, doctors recommend: Avoid or quit smoking (especially if also taking birth control pills or hormone therapy). When traveling on a long trip, get up and walk every couple of hours.

What is the function of the veins?

Veins are flexible, hollow tubes with interior flaps (valves) that open when the muscles contract, moving blood through the veins back to the heart. When the muscles relax, the valves close, keeping blood from flowing away from the heart.

What happens if a valve is damaged?

If the valves become damaged, they may not close completely , allowing blood to flow “backward” (retrograde), resulting in the pooling of blood and swelling in the veins that cause pressure to buildup in the vein. The pressure causes stretching of the veins, increased swelling, more valve incompetence, sluggish blood flow, ...

What is the condition that causes numbness in the legs and feet?

Why do my leg veins not flow back up to my heart?

Chronic venous insufficiency occurs when your leg veins don’t allow blood to flow back up to your heart. Normally, the valves in your veins make sure that blood flows toward your heart. But when these valves don’t work well, blood can also flow backwards. This can cause blood to collect (pool) in your legs.

How is chronic venous insufficiency diagnosed?

Your provider will take your medical history and give you an exam. You may also have an imaging test called a Duplex ultrasound. This looks at blood flow and the structure of your leg veins. It checks the speed and direction of blood flow in the blood vessel.

What is an endovenous laser?

Endovenous laser ablation or radiofrequency ablation (RFA). This is a minimally invasive procedure. A tube (catheter) puts heat right into the affected vein. This closes the vein. Once the vein is closed, less blood pools in the leg. Overall blood flow is improved.

What is a varicose vein?

What is a blood clot in the calf called?

A blood clot in a deep vein, often in the calf or thigh (deep vein thrombosis)

Why do veins in legs cause venous issues?

Most commonly, venous issues occur in the legs because vein valves located in your legs have weakened to the point where they can no longer allow proper blood flow. The weakening causes venous blood to collect in weak veins making them work as vein valves located elsewhere in your body to circulate blood.

What Happens During a Treatment for Damaged Leg Veins?

Chronic venous hypertension could also result from an obstruction in the veins due to blood clotting, obesity or the compression of pelvic or abdominal veins.

What happens when blood is pumped into the legs?

Once the vein valves become weakened or damaged and stop functioning at their highest capacity, blood can begin to pool in the leg, resulting in pain, swelling and any number of venous conditions.

Why do vein valves revert when standing?

Damaged venous valves that no longer function properly can result in the reversal of blood through the valves when people with this condition are sitting or standing. This condition, known as venous reflux, most often occurs when vein valves become weakened due to genetic influences, multiple pregnancies, blood clots or high blood pressure.

How to know if you have a deep vein thrombosis?

Keep an eye out for the most common sign and symptoms of deep vein thrombosis, including swelling, leg pain, red or discolored skin around the leg vein or a feeling of warmth within the affected leg.

Why do my legs have bulging veins?

When the superficial vein valves become damaged, weak, or defective, blood leaks backwards (venous reflux) causing the blood to pool in the leg veins. Pooling of blood leads to inflammation and high pressure in the veins causing further damage to other valves or branch veins such as tributaries and reticular veins. It also causes veins to stretch and dilate, weakening and thinning the vein walls. This eventually leads to tortuous, twisted, bulging veins. These damaged veins ultimately become varicose and spider veins, depending on which veins are affected.

What causes blood to move backwards in the leg veins?

When deep vein valve failure occurs, blood moves in the reverse direction. Venous pressure in the deep system is generally greater than that of the superficial system. Valve failure causes the blood to leak backwards into the superficial veins resulting in multi-system failure causing pooling of blood and excessive pressure in the leg veins.

Why do veins pool in legs?

When these valves become damaged, weak, or defective and don’t work well, blood flows backwards. This can cause blood to collect (pool) in your legs. Pooling of blood in the leg veins is the root cause of varicose and spider veins and their associated symptoms.

Clinical significance

  • Chronic venous insufficiency (CVI) is a condition that occurs when the venous wall and/or valves in the leg veins are not working effectively, making it difficult for blood to return to the heart from the legs. CVI causes blood to pool or collect in these veins, and this pooling is called stasis.

Function

  • Veins return blood to the heart from all the bodys organs. To reach the heart, the blood needs to flow upward from the veins in the legs. Calf muscles and the muscles in the feet need to contract with each step to squeeze the veins and push the blood upward. To keep the blood flowing up, and not back down, the veins contain one-way valves.
