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 artery disease (PAD).
FMD is a noninvasive measure of blood vessel health (endothelial dysfunction [5] [6]) which (when low) is at least as predictive of cardiovascular disease as traditional risk factors. [ 4 ] [ 7 ] [ 8 ] Major cardiovascular disease associated with low FMD include cardiac death , myocardial infarction , and stroke .
Normal blood vessel (left) vs. vasodilation (right) Vasodilation, also known as vasorelaxation, is the widening of blood vessels. [1] It results from relaxation of smooth muscle cells within the vessel walls, in particular in the large veins, large arteries, and smaller arterioles. [2]
[5] [46] The swelling of the soft tissues around the blood vessels compresses the blood and lymphatic vessels. [46] [44] This causes more fluid to enter the extracellular spaces, leading to further compression. [5] The pressure keeps rising due to the non-compliant fascia in the compartment. [5]
In the legs, bypass grafting is used to treat peripheral vascular disease, acute limb ischemia, aneurysms and trauma.While there are many anatomical arrangements for vascular bypass grafts in the lower extremities depending on the location of the disease, the principle is the same: to restore blood flow to an area without normal flow.
An arterial line is usually inserted into the radial artery in the wrist, but can also be inserted into the brachial artery at the elbow, into the femoral artery in the groin, into the dorsalis pedis artery in the foot, or into the ulnar artery in the wrist. [2]

Furthermore, ABI values of 0.91 to 0.99 are considered borderline, and values >1.40 indicate noncompressible arteries. If an ABI >1.40 is calculated, this could indicate vessel wall stiffness caused by calcification, which can occur in people with uncontrolled diabetes.
