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 dise
Segmental blood pressure is used to measure actual limb blood pressure, to assess and locate arterial occlusion. On the legs, pressure is measured at the ankle, below the knee, above the knee, and mid-thigh. On the arm, measurements are taken at the wrist, below the elbow, above the elbow, and mid-upper arm.

The brachial artery is the major blood vessel of the (upper) arm. It is the continuation of the axillary artery beyond the lower margin of teres major muscle. It continues down the ventral surface of the arm until it reaches the cubital fossa at the elbow. It then divides into the radial and ulnar arteries which run down the forearm.
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.
In human anatomy, the dorsalis pedis artery (dorsal artery of foot) is a blood vessel of the lower limb. It arises from the anterior tibial artery, and ends at the first intermetatarsal space (as the first dorsal metatarsal artery and the deep plantar artery). It carries oxygenated blood to the dorsal side of the foot. It is useful for taking a ...
ACS is defined as a critical pressure increase within a confined compartmental space causing a decline in the perfusion pressure to the tissue within that compartment . [5] A normal human body needs a pressure gradient for blood flow. [43] It must go from the higher-pressure arterial system to the lower-pressure venous system.
To image the lower limb vascular anatomy, the common femoral artery (CFA) is chosen as the site of entry. However, CFA entry can only be assessed by retrograde puncture. Therefore, a catheter is advanced retrogradely through the contralateral common femoral artery into common iliac artery, crossing the midline into ipsilateral CFA.
Blood vessels and nerves can also be affected by the pressure caused by any swelling in the leg. If the pressure becomes great enough, blood flow to the muscle can be blocked, leading to a condition known as compartment syndrome. Severe damage to the nerve and blood vessels around a muscle can cause the muscle to die and amputation might be ...
