Peripheral artery disease most commonly affects the legs, but other arteries may also be involved, such as those of the arms, neck, or kidneys. [4] [17] Peripheral artery disease (PAD) is a form of peripheral vascular disease. Vascular refers to both the arteries and veins within the body. PAD differs from peripheral veinous disease. PAD means ...
In an ischaemic leg, elevation to 15 degrees or 30 degrees for 30 to 60 seconds may cause pallor. (This part of the test checks for elevation pallor.) A vascular angle of less than 20 degrees indicates severe ischaemia. [1] [2] From a sitting position, in normal circulation, the foot will quickly return to a pink colour.
Peripheral artery disease is typically diagnosed if the systolic blood pressure in the ankle divided by the systolic blood pressure in the arm is less than 0.9. In general, claudication is often seen in people with an ABI between 0.4 and 0.9, rest pain is seen between 0.2 and 0.4, and tissue loss, ulcers, and gangrene between 0 to 0.4.
A peripheral vascular examination is a medical examination to discover signs of pathology in the peripheral vascular system. It is performed as part of a physical examination, or when a patient presents with leg pain suggestive of a cardiovascular pathology. The exam includes several parts: Position/lighting/draping; Inspection; Palpation ...
The ABPI test is a popular tool for the non-invasive assessment of Peripheral vascular disease (PVD). Studies have shown the sensitivity of ABPI is 90% with a corresponding 98% specificity for detecting hemodynamically significant ( stenosis of more than 50%) in major leg arteries, defined by angiogram.

The peripheral vascular system is the part of the circulatory system that consists of the veins and arteries not in the chest or abdomen (i.e. in the arms, hands, legs and feet). [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 ...
