In
human anatomy, the
dorsalis pedis artery (
dorsal artery of foot), is a
blood vessel of the
lower limb that carries oxygenated blood to the
dorsal surface of the
foot. It arises at the anterior aspect of the ankle joint and is a continuation of the
anterior tibial artery. It terminates at the proximal part of the first intermetatarsal space, where it divides into two branches, the first
dorsal metatarsal artery and the
deep plantar artery.
Along its course, it is accompanied by a deep vein, the dorsalis pedis vein.
Palpation of the dorsalis pedis artery pulse
The dorsalis pedis artery
pulse can be
palpated readily lateral to the
extensor hallucis longus tendon on the dorsal surface of the
foot, distal to the dorsal most prominence of the
navicular bone which serves as a reliable landmark for palpation. It is often examined, by
physicians, when assessing whether a given patient has
peripheral vascular disease. It is absent, unilaterally or bilaterally, in 2-3 % of young healthy individuals.
