Ankle–brachial pressure index 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 artery disease (PAD). The ABPI is calculated by dividing the systolic blood pressure at the ankle by the systolic blood pressure in the arm. The patient must be placed supine, without the head or any extremities dangling over the edge of the table. Measurement of ankle blood pressures in a seated position will
Deep artery of the thigh thigh gives off the following branches: Deep artery of the thigh The deep artery of the thigh, (profunda femoris artery or deep femoral artery) is a branch of the femoral artery that, as its name suggests, travels more deeply (posteriorly) than the rest of the femoral artery. The deep artery of the thigh branches off the femoral artery soon after its origin. It travels down the thigh closer to the femur than the femoral artery, running between the pectineus and the adductor longus, and running on the posterior side of adductor longus. The deep femoral artery does not leave the
