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.
The origin of the small saphenous vein (SSV) is where the dorsal vein from the fifth digit (smallest toe) merges with the dorsal venous arch of the foot, which attaches to the great saphenous vein (GSV). It is a superficial vein, being subcutaneous (just under the skin).
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]
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.
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 ().

The Giacomini vein or cranial extension of the small saphenous vein [1] is a communicating vein between the great saphenous vein (GSV) and the small saphenous vein (SSV). It is named after the Italian anatomist Carlo Giacomini (1840–1898). The Giacomini vein courses the posterior thigh as either a trunk projection, or tributary of the SSV.
