; Varicose veins: Veins that have become enlarged and tortuous with failed valves, commonly in the legs.

# REDIRECT Varicose veins

Varicose veins are veins that have become enlarged and tortuous.

Varicose veins are distinguished from reticular veins ( blue veins ) and telangiectasias ( spider veins ), which also involve valvular insufficiency, by the size and location of the veins.

Varicose veins are more common in women than in men, and are linked with heredity.

Varicose veins that form during pregnancy may spontaneously improve or even disappear a few months after delivery.

Varicose veins and reticular leg veins, if present, must be treated prior to any treatment of the telangiectasia.

Varicose veins can be treated with foam sclerotherapy, endovenous laser treatment, radiofrequency ablation or open surgery.

Varicose veins and chronic conditions or infections that affect the blood flow in the legs account for potential causes of stasis dermatitis.

Varicose waves on the surface of the jet lead to the formation of small and highly charged liquid droplets, which are radially dispersed due to Coulomb repulsion.

Varicose veins ( that may or may not be visible ) can also cause compression of the nerve.

Arteries and veins are apparent by their black, blood-filled centers and the surrounding white walls.

Arteries and veins are part of the human cardiovascular system.

Some of the synapomorphies of the order are: leaves in spiral, secondary veins palmated, calyx or perianth valvate, elevated stomatal calyx / perianth with separate styles.

Most variations are due to coughing or internal compression of jugular veins in the neck.

There are two veins of thought concerning the Grail's origin.

The characteristic swirls and veins of many colored marble varieties are usually due to various mineral impurities such as clay, silt, sand, iron oxides, or chert which were originally present as grains or layers in the limestone.

Targets are divided into two general categories of materials: placer deposits, consisting of valuable minerals contained within river gravels, beach sands, and other unconsolidated materials ; and lode deposits, where valuable minerals are found in veins, in layers, or in mineral grains generally distributed throughout a mass of actual rock.

The leaves are from long and cm broad, dark green with reddish veins, and with an acute apex and coarsely toothed margins.

The cellular consequences of ARF activation depend on the plant type and developmental stage, but are involved in directing growth in roots and leaf veins.

In nature, veins acting as valves are controlling the blood circulation ; heart valves control the flow of blood in the chambers of the heart and maintain the correct pumping action.

Secondary varicose veins are those developing as collateral pathways, typically after stenosis or occlusion of the deep veins, a common sequel of extensive deep venous thrombosis ( DVT ).

Most varicose veins are relatively benign, but severe varicosities can lead to major complications, due to the poor circulation through the affected limb.

The jugular veins also contain several ( most commonly seven ) valves to prevent blood flowing back into the head from the inferior vena cava and right atrium while the head is lowered.

Because most of the blood in the legs is returned by the deep veins, the superficial veins, which return only about 10 per cent of the total blood of the legs, can usually be removed or ablated without serious harm.

Veins are also called " capacitance vessels " because most of the blood volume ( 60 %) is contained within veins.

Although most veins take blood back to the heart, there is an exception.

Venous insufficiency is the most common disorder of the venous system, and is usually manifested as spider veins or varicose veins.

The most common was phlebotomy, or venesection ( often called " breathing a vein "), in which blood was drawn from one or more of the larger external veins, such as those in the forearm or neck.

In 1887, these early mines largely shut down, as most of the richest and easy-to-reach veins of ore had been exhausted.

Note that, contrary to popular belief, the most common site of origin of pulmonary emboli are the femoral veins, not the deep veins of the calf.

Deep veins of the calf are the most common site of thrombi, not emboli origin.

Another is that the veins of the leaves, between major veins, are reticulate ( net-shaped ), rather than parallel as in most monocots.

The geomuseum has an extensive collection of local minerals, most notably minerals from the pegmatite veins in the Evje-Iveland district.

The most convenient site is often the arm, especially the veins on the back of the hand, or the median cubital vein at the elbow, but any identifiable vein can be used.

Any accessible vein can be used although arm and hand veins are used most commonly, with leg and foot veins used to a much lesser extent.

It most commonly affects leg veins, such as the femoral vein.

PE most commonly results from deep vein thrombosis ( a blood clot in the deep veins of the legs or pelvis ) that breaks off and migrates to the lung, a process termed venous thromboembolism ( VTE ).

In APS patients, the most common venous event is deep vein thrombosis of the lower extremities ( blood clot of the deep veins of the legs ) and the most common arterial event is stroke.

It collects most of the lymph in the body ( except that from the right arm and the right side of the chest, neck and head, and lower left lobe of the lung, which is collected by the right lymphatic duct ) and drains into the systemic ( blood ) circulation at the left brachiocephalic vein between the left subclavian and left internal jugular veins.
