Inhuman anatomy,thedorsalis pedis artery(dorsal artery of foot) is ablood vesselof thelower limb.It arises from theanterior tibial artery,and ends at the first intermetatarsal space (as thefirst dorsal metatarsal arteryand thedeep plantar artery). It carries oxygenated blood to thedorsalside of thefoot.It is useful for taking apulse.It is also at risk duringanaesthesiaof thedeep peroneal nerve.

Structure
editThe dorsalis pedis artery is located 1/3 frommedial malleolusof theankle.It arises at the anterior aspect of the ankle joint and is a continuation of theanterior tibial artery.[1][2]It ends at the proximal part of the first intermetatarsal space. Here, it divides into two branches, thefirst dorsal metatarsal artery,and thedeep plantar artery.[2]It is covered by skin and fascia, but is fairly superficial.[2]
The dorsalis pedis communicates with the plantar blood supply of the foot through the deep plantar artery. Along its course, it is accompanied by adeep vein,thedorsalis pedis vein.
Function
editThe dorsalis pedis artery supplies oxygenated blood to thedorsalside of thefoot.[1]
Clinical significance
editPulse
editThe dorsalis pedis arterypulsecan bepalpatedreadily lateral to theextensor hallucis longustendon(or medially to theextensor digitorum longustendon) on the dorsal surface of thefoot,distal to the dorsal most prominence of thenavicular bonewhich serves as a reliable landmark for palpation.[3]It is often examined, byphysicians,when assessing whether a given patient hasperipheral vascular disease.It is absent, unilaterally or bilaterally, in 2–3% of young healthy individuals.[4]
Ultrasound
editThe dorsalis pedis artery may be studied usingultrasound.[2]Doppler ultrasoundcan be used to investigate blood flow.[2]
Local anaesthesia
editThe dorsalis pedis artery is at risk when injectinganaestheticinto thedeep peroneal nerve.[5]Ultrasoundcan be used to help to avoid the artery.[5]The injection site is just lateral to the artery.[5]
