  2. Arterial insufficiency ulcer - Wikipedia

    en.wikipedia.org/wiki/Arterial_insufficiency_ulcer

    The ulcers are caused by lack of blood flow to the capillary beds of the lower extremities. Most often endothelial dysfunction is causative factor in diabetic microangiopathy and macroangiopathy. [2] In microangiopathy, neuropathy and autoregulation of capillaries leads to poor perfusion of tissues, especially wound base.

  3. Livedoid vasculopathy - Wikipedia

    en.wikipedia.org/wiki/Livedoid_vasculopathy

    Livedoid vasculopathy (LV) is an uncommon thrombotic dermal vasculopathy that is characterized by excruciating, recurrent ulcers on the lower limbs. [4] Livedo racemosa, along with painful ulceration in the distal regions of the lower extremities, is the characteristic clinical appearance.

  4. Monckeberg's arteriosclerosis - Wikipedia

    en.wikipedia.org/wiki/Monckeberg's_arteriosclerosis

    A. Pelvic and lower extremity radiograph shows extensive calcification of the femoral arteries. B. Translumbar aortography shows near-total obstruction of the femoral arteries. Mönckeberg's arteriosclerosis, or Mönckeberg's sclerosis, is a non-inflammatory form of arteriosclerosis (artery hardening), which differs from atherosclerosis ...

  5. Atherosclerosis - Wikipedia

    en.wikipedia.org/wiki/Atherosclerosis

    Atherosclerosis [a] is a pattern of the disease arteriosclerosis, [8] characterized by development of abnormalities called lesions in walls of arteries.This is a chronic inflammatory disease involving many different cell types and driven by elevated levels of cholesterol in the blood. [9]

  6. Popliteal artery entrapment syndrome - Wikipedia

    en.wikipedia.org/wiki/Popliteal_artery...

    Analysis of human embryological development has shown that the popliteal artery and the medial head of the gastrocnemius muscle arise at approximately the same time. Because of that, abnormal development of muscle's position in relation to the nearby vessels can result in potential vascular compromise. [ 3 ]

  7. Peripheral artery disease - Wikipedia

    en.wikipedia.org/wiki/Peripheral_artery_disease

    Nonhealing lower extremity wound [38] If peripheral artery disease is suspected, the initial study is the ankle–brachial index (ABI). [ 20 ] The ABI is a simple, non-invasive test that measures the ratio of systolic blood pressure in the ankle to the systolic blood pressure in the upper arm.

  8. Phlegmasia cerulea dolens - Wikipedia

    en.wikipedia.org/wiki/Phlegmasia_cerulea_dolens

    A person with a two hour history of phlegmasia cerulea dolens (left leg, right side of image) Phlegmasia cerulea dolens (PCD) (literally: 'painful blue inflammation'), not to be confused with preceding phlegmasia alba dolens , is an uncommon severe form of lower extremity deep venous thrombosis (DVT) that obstructs blood outflow from a vein.

  9. Livedo reticularis - Wikipedia

    en.wikipedia.org/wiki/Livedo_reticularis

    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 ().
