Dilated blood vessels can also develop on the legs, although when they occur on the legs, they often have underlying venous reflux or "hidden varicose veins" (see Venous hypertension section below). When found on the legs, they are found specifically on the upper thigh, below the knee joint and around the ankles.
This is a rare condition in which blood clots occur in the iliofemoral vein due to compression of the blood vessels in the leg. The specific problem is compression of the left common iliac vein by the overlying right common iliac artery. Many May-Thurner compressions are overlooked when there is no blood clot.
Vascular disease is a class of diseases of the vessels of the circulatory system in the body, including blood vessels – the arteries and veins, and the lymphatic vessels. Vascular disease is a subgroup of cardiovascular disease. Disorders in this vast network of blood and lymph vessels can cause a range of health problems that can sometimes ...
Variable vessel vasculitis (VVV) is a kind of vasculitis that may impact vessels of all sizes (small, medium, and large) and any type (arteries, veins, and capillaries), with no particular type of vessel being predominantly affected. [33] This category includes Behcet's disease (BD) and Cogan's syndrome (CS). [8]
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.
Because of its similarities to deep vein thrombosis (DVT), May–Thurner syndrome is rarely diagnosed amongst the general population. In this condition, the right iliac artery sequesters and compresses the left common iliac vein against the lumbar section of the spine, [5] resulting in swelling of the legs and ankles, pain, tingling, and/or numbness in the legs and feet. [6]
Peripheral artery disease (PAD) is a vascular disorder that causes abnormal narrowing of arteries other than those that supply the heart or brain. [5] [15] PAD can happen in any blood vessel, but it is more common in the legs than the arms. [16]
Golfer's vasculitis, also called exercise-induced vasculitis, sport-induced vasculitis, Disney rash, or hiker's rash, is a form of small blood vessel inflammation resulting in a rash. [1] It occurs in the lower legs, and is caused by excessive walking in hot temperatures. It is more common in elderly people.
