The pathophysiology is not yet well understood. Leukocytoclastic vasculitis is proposed to be the underlying cause resulting in reactive lymphedema. [2] Prolonged standing with full knee extension and minimal movement for a prolonged period of time is postulated to induce a temporary failure in pumping the venous and lymphatic systems in the calf region leading to acute gravity-dependent ...
The definite diagnosis of vasculitis is established after a biopsy of involved organ or tissue, such as skin, sinuses, lung, nerve, brain, and kidney. The biopsy elucidates the pattern of blood vessel inflammation. Some types of vasculitis display leukocytoclasis, which is vascular damage caused by nuclear debris from infiltrating neutrophils. [37]
Next check for rubor of dependency. Sit the patient upright and observe the feet. In normal patients, the feet quickly turn pink. If, more slowly, they turn red like a cooked lobster, suspect ischemia. Brodie-Trendelenburg test (assessment of valvular competence if varicose veins are present): One leg at a time.
The reversed blood pools in the low third of legs and feet. [17] Unlike in the arterial ultrasound study, when the sonographer studies venous insufficiency, the vein wall itself has no relevance and attention is focused on the direction of blood flow. The objective of the examination is to see how the veins drain.
Necrotizing vasculitis, also called systemic necrotizing vasculitis, [1] is a general term for the inflammation of veins and arteries that develops into necrosis and narrows the vessels. [ 2 ] Tumors , medications, allergic reactions , and infectious organisms are some of the recognized triggers for these conditions, even though the precise ...
Peripheral artery disease – occurs when atheromatous plaques build up in the arteries that supply blood to the arms and legs, causing the arteries to narrow or become blocked. [ 1 ] Erythromelalgia - a rare peripheral vascular disease with symptoms that include burning pain, increased temperature, erythema and swelling that generally affect ...
If no underlying cause is found and the vasculitis is truly limited to the skin then treatment is primarily supportive. [13] Such treatment involves measures such as leg elevation, stockings, and topical steroids to relieve itching/burning. If the vasculitis does not self-resolve within 3–4 weeks, more aggressive treatment may be warranted. [13]
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.
