There are three main categories of veins. Deep leg veins return blood directly to the heart and are in the center of the leg, near the bones. Superficial leg veins are just beneath the skin. Perforator veins serve as connections between the superficial system and the deep system of the leg veins.
The superficial leg veins have less support from surrounding bone and muscle than the deep veins. There may be a development, at some point, of weakening of the wall. If ballooning of the vein occurs, the vein becomes varicose.
Varicose ulcers point to underlying medical conditions and underlying medical conditions that might have varicose ulcers as a complication; thats pretty clear, isnt it?
Varicose ulcers, then, are really a big fat symptom then, isnt it, coming and going, an outcome, an artless guest to the party who keeps pointing at the eight hundred pound gorilla in the room.
A skin ulcer, therefore, that points to the missing loss of skin, the ulcer, therefore who sits right on top of the veins. Usually aching leads to cramping, to itching, to skin staining to eczema to finally, the ulcers. They can be very painful; can bleed and become infected. Most ulcers can be healed.
The key is to put a pressure bandage of some kind on the underlying veins, in other words, squeeze the veins with bandages, and in sixteen weeks the ulcer can be vanquished. Every week the bandage can be changed and the ulcer needs to be measured to make sure that it is healing. If the ulcer is on the leg, knee, or ankle, the most straightforward cure would be simply going to bed and putting the feet up.
Now the clot, or thrombus, is a craftier little devil who likes to hide to do its mischief. The thrombus forms in the larger veins deep within the leg. Undetected, deep vein thrombosis can lead to a pulmonary embolism, which is an obstruction of a blood vessel in the lungs, usually as a clot. If it blocks the pulmonary artery can be very serious and in some cases, fatal.
Yes, the clot can interfere with the blood flow, or break off and travel through the bloodstream (embolize). Traveling clots can wind up in the lung, as stated, but it can also head for the brain and heart just as well.
Phlebitis is the inflammation of a vein often caused by prolonged inactivity such as a long flight or travel, or during extended bed rest. This is when a clot may form. Certain types of cancer, paralysis or use of the hormone estrogen may also cause phlebitis.
It almost seems anticlimactic to introduce the last vein-y denizen of the leg, the humble spider vein. This one, unlike his larger brethren, doesnt pose a health threat, but still does its largely emotional damage.
This network of tiny vessels is akin to a spiders web, and that is how it got its name. The Telangiectasia is seen on the face, and the Arborising Telangiectasia is the good neighbor to the south that inhabits the legs and thighs.
