DVT usually occurs in the veins of the legs, although it can also occur in the veins of the arms. Immobility, active cancer, obesity, traumatic damage and congenital disorders that make clots more likely are all risk factors for deep vein thrombosis. It can cause the affected limb to swell, and cause pain and an overlying skin rash.
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.

[1] [2] The peripheral arteries supply oxygenated blood to the body, and the peripheral veins lead deoxygenated blood from the capillaries in the extremities back to ...
Chronic venous insufficiency (CVI) is a medical condition in which blood pools in the veins, straining the walls of the vein. [1] The most common cause of CVI is superficial venous reflux, which is a treatable condition. [2]
