The dorsalis pedis artery is located 1/3 from medial malleolus of the ankle. It arises at the anterior aspect of the ankle joint and is a continuation of the anterior tibial artery. [1][2] It ends at the proximal part of the first intermetatarsal space. Here, it divides into two branches, the first dorsal metatarsal artery, and the deep plantar ...
The posterior tibial artery arises from the popliteal artery in the popliteal fossa. [ 1 ] It is accompanied by a deep vein, the posterior tibial vein, along its course. It passes just posterior to the medial malleolus of the tibia, but anterior to the Achilles tendon. [ 1 ] It passes into the foot deep to the flexor retinaculum of the foot. [ 1 ]
Dorsalis pedis artery pulse – on dorsal surface of the foot, running lateral to the tendon of the first toe; Posterior tibial artery pulse – posterior and inferior to the medial malleolus; Popliteal artery pulse – behind the knee, typically done with both hands
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 ...
Close to the ankle joint, the deep fibular nerve terminates by dividing into medial and lateral terminal branches. [1]Medial terminal branch: This nerve accompanies the dorsalis pedis artery along the dorsum of the foot, and, at the first interosseous space, divides into two dorsal digital nerves which supply the adjacent sides of the great and second toes, [1] communicating with the medial ...
The pulse may be palpated in any place that allows an artery to be compressed near the surface of the body, such as at the neck (carotid artery), wrist (radial artery or ulnar artery), at the groin (femoral artery), behind the knee (popliteal artery), near the ankle joint (posterior tibial artery), and on foot (dorsalis pedis artery). The ...
If the femoral pulse is strong, but the popliteal pulse is weak, this can indicate atherosclerosis of the vessels in the thigh. [2] Finally, the posterior tibial and dorsalis pedis arteries provide a good indicator of circulation to the extremities. These can be palpated just behind the ankle and on the top of the foot, respectively. [3]
The arcuate artery of the foot (metatarsal artery) arises from dorsalis pedis slightly anterior to the lateral tarsal artery, specifically over the naviculocuneiform joint; it passes lateralward, over the bases of the lateral four metatarsal bones, beneath the tendons of the extensor digitorum brevis, its direction being influenced by its point of origin; and it terminates in the lateral ...
