Blood vessel disorder generally refers to the narrowing, hardening or enlargement of arteries and veins. It is often due to the build-up of fatty deposits in the lumen of blood vessels or infection of the vessel wall. This can occur in various locations such as coronary blood vessels, peripheral arteries and veins.
A spider angioma or spider naevus (plural: spider naevi), also nevus araneus, is a type of telangiectasis [2] (swollen, spider-like blood vessels on the skin) found slightly beneath the skin's surface, often containing a central red spot and deep reddish extensions (see Blood color) which radiate outwards like a spider's web or a spider's legs.
Traditionally, varicose veins were investigated using imaging techniques only if there was a suspicion of deep venous insufficiency, if they were recurrent, or if they involved the saphenopopliteal junction. This practice is now less widely accepted. People with varicose veins should now be investigated using lower limbs venous ultrasonography.
Now I have the routine down—I apply lidocaine to numb my arm about half an hour before my nurse arrives, so that when the needle is in for an hour and a half, I don’t feel it as much.
Varicose veins and reticular veins are often treated before treating telangiectasia, although treatment of these larger veins in advance of sclerotherapy for telangiectasia may not guarantee better results. [18] [19] [20] Varicose veins can be treated with foam sclerotherapy, endovenous laser treatment, radiofrequency ablation, or open
Most cases of CVI can be improved with treatments to the superficial venous system or stenting the deep system. Varicose veins, for example, can now be treated by local anesthetic endovenous surgery. Rates of CVI are higher in women than in men. [4] [5] Other risk factors include genetics, smoking, obesity, pregnancy, and prolonged standing. [6]
If blood travels too slowly and starts to pool in the leg veins, the pressure can force too much fluid out of the leg capillaries into the tissue spaces. The capillaries may break, leaving small blood marks under the skin. The veins themselves can become swollen, painful and distorted – a condition known as varicose veins. [17]
The electrons from the sun interact with the Earth's magnetic field and collide with various molecules in our atmosphere. "And because of those interactions eventually light is released.
