Ankle–brachial pressure index types of leg ulcers: Studies in 2006 suggests that an abnormal ABPI may be an independent predictor of mortality, as it reflects the burden of atherosclerosis. It thus has potential for screening for coronary artery disease, although no evidence-based recommendations can be made about screening in low-risk patients because clinical trials are lacking. Ankle–brachial pressure index The ankle-brachial pressure index (ABPI) or ankle-brachial index (ABI) is the ratio of the blood pressure at the ankle to the blood pressure in the upper arm (brachium). Compared to the arm, lower blood pressure in the leg suggests blocked arteries due to peripheral
Axillary artery axillary vein, which lies medial to the artery, along its length. In the axilla, the axillary artery is surrounded by the brachial plexus. The second part of the axillary artery is the reference for the locational descriptions of the cords in the brachial plexus. For example, the posterior cord of the brachial plexus is so named because it lies posterior to the second part of the artery. The axillary artery has several smaller branches. The branches can be remembered, in order, when traveling from the heart, with the mnemonics "Screw The Lawyers Save A Patient", "Summertime: The Lakers Schedule Another
