what are spider veinlets?

Question

cause, prevention and cure

Answer 1

Telangiectasias, or spider veins, are small enlarged blood vessels near the surface of the skin; usually they measure only a few millimeters. They can develop anywhere on the body but commonly on the face around the nose, cheeks, and chin. They can also develop on the legs, specifically on the upper thigh, below the knee joint, and around the ankles.

These are actually developmental abnormalities but can closely mimic the behaviour of benign vascular neoplasms. They may be composed of abnormal aggregations of arterioles, capillaries, or venules.

Chronic treatment with topical corticosteroids may lead to telangiectasia.[1]

Features
Telangiectasias can result in naevus flammeus (port-wine stain), which is a flat birthmark on the head or neck that spontaneously regresses. A port-wine stain, if present, will grow proportionately with the child. There is a high association with Sturge-Weber syndrome, a nevus formation in the skin supplied by the trigeminal nerve and associated with glaucoma, meningeal angiomas, and mental retardation. Finally, spider telangiectasias are a radial array of tiny arterioles that commonly occur in pregnant women and in patients with hepatic cirrhosis. In men, they are related to high estrogen levels secondary to liver disease.

Sclerotherapy is a nonsurgical office procedure that can treat most diseased surface veins. Medication is dripped into a vein using an extremely tiny needle. The medication closes down the vein walls so that they stick together and are gradually reabsorbed by the body. Getting rid of these diseased veins actually improves the circulation and makes the legs healthier.

Laser Spider Vein Treatments
Laser Spider Vein Treatments uses a powerful beam of light to gently heat the blood vessel, closing it off and making it smaller or, in most cases, making it disappear completely. The laser does not damage the skin. The treatment is non-invasive- no needles, no cutting, no bruises.

Ultrasound Guided Sclerotherapy
Ultrasound Guided Sclerotherapy uses ultrasound technology to aid the penetrating deep vascular problems. Once the root cause of the vacular problem is identified via ultrasound, sclerotherapy is then used to treat the problem area.

Endovenous Laser Therapy
EVLT, is a nonsurgical office procedure that can treat larger and deeper veins. A small catheter is threaded inside the vein, and flashes of laser light are used to treat the inside of the vein walls so that they stick together and are gradually reabsorbed by the body. Laser therapy and intense pulsed light therapy, which is constantly improving, is a good option for individuals with a "needle phobia" or who, for other reasons, are not candidates for sclerotherapy.

Answer 2

Spider veins are tiny clusters of capillaries that show on the skin, can appear on any part of the body, may possibly be related to liver function if you get a batch of them in a short time (and facial skin has a yellowish tint). Medical word is telangiectasis. If you press on one, release, watch the color. The blood returns to skin from the center out.
Don't know about the cure, but they do fade in time. I've seen ads for removal of spider veins and varicose veins.
Try website www.veinsonline.com but they're trying to sell a service so it sounds worse than it is.
