Peripheral artery disease peripheral artery disease: If peripheral artery disease is suspected, the initial study is the ankle–brachial index (ABI). The ABI is a simple, non-invasive test, which measures the ratio of systolic blood pressure in the ankle to the systolic blood pressure in the upper arm. This is based on the idea that if blood pressure readings in the ankle are lower than those in the arm, a blockage in the arteries that provide blood from the heart to the ankle is suspected. An ABI range of 0.90 to 1.40 is considered normal. A person is considered to have PAD when the
Deep artery of the thigh 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 thigh. The deep artery of the
