Telangiectasia in the legs is often related to the presence of venous reflux within underlying varicose veins. Flow abnormalities in smaller veins known as reticular veins or feeder veins under the skin can also cause spider veins to form, thereby making a recurrence of spider veins in the treated area less likely.
Particular veins of the deep venous system (DVS), and the superficial venous system (SVS) are looked at. The great saphenous vein (GSV), and the small saphenous vein (SSV) are superficial veins which drain into respectively, the common femoral vein and the popliteal vein. These veins are deep veins.
The distal veins are removed following the complete ablation of the proximal vein. This treatment is most commonly used for varicose veins off of the great saphenous vein, small saphenous vein, and pudendal veins. [60] Follow-up treatment to smaller branch varicose veins is often needed in the weeks or months after the initial procedure.
Chronic venous insufficiency (CVI) is a medical condition characterized by blood pooling in the veins, leading to increased pressure and strain on the vein walls. [1] The most common cause of CVI is superficial venous reflux, which often results in the formation of varicose veins, a treatable condition. [2]
Livedo reticularis is a common skin finding consisting of a mottled reticulated vascular pattern that appears as a lace-like purplish discoloration of the skin. [1] The discoloration is caused by reduction in blood flow through the arterioles that supply the cutaneous capillaries, resulting in deoxygenated blood showing as blue discoloration ().
Superficial thrombophlebitis is a thrombosis and inflammation of superficial veins presenting as a painful induration (thickening) with erythema, often in a linear or branching configuration with a cordlike appearance. [2]: 826–7 [3] Superficial thrombophlebitis is due to inflammation and/or thrombosis, and,less commonly, infection of the vein.

Cutaneous small-vessel vasculitis (CSVV) is inflammation of small blood vessels, usually accompanied by small lumps beneath the skin. [1]: 831 [2] The condition is also known as hypersensitivity vasculitis, cutaneous leukocytoclastic vasculitis, hypersensitivity angiitis, cutaneous leukocytoclastic angiitis, cutaneous necrotizing vasculitis and cutaneous necrotizing venulitis, [3]
