Dorsalis Metatarsal Arteries, Dorsal View

Description

Running along the dorsum of a male foot, the dorsalis pedis artery continues distally from the anterior tibial artery and gives off the arcuate artery across the bases of the metatarsals. From this dorsal arch, the dorsalis metatarsal arteries course anteriorly in the second through fourth intermetatarsal spaces, lying superficial to the dorsal interossei and deep to the dorsal venous network. Distally, each vessel approaches the metatarsophalangeal joints and divides into dorsal digital branches toward adjacent toes. Small arterioles and accompanying veins track alongside the named arteries. Clean topology. This dorsal arterial pattern matters when you need surface oriented landmarks for pedal perfusion, because the dorsalis pedis pulse is palpated lateral to the tendon of extensor hallucis longus and can be diminished in peripheral arterial disease, diabetes related vasculopathy, or acute limb ischemia. For forefoot surgery, the intermetatarsal course of the dorsalis metatarsal arteries helps you plan incisions for dorsal approaches to the metatarsals and MTP joints while avoiding troublesome bleeding and preserving collateral flow to the toes. The illustration also supports interpretation of Doppler ultrasound or CT angiography by clarifying how dorsal metatarsal branches relate to the interspaces. Use this artwork in gross anatomy and lower limb dissection teaching, vascular anatomy modules, and podiatric or orthopedic publishing that discusses pedal pulses, forefoot approaches, or microvascular assessment in diabetic foot clinics. It also fits patient education materials explaining where clinicians check circulation on the top of the foot. Anatomical accuracy verified by SciePro's Medical Advisory Board.
