Dorsalis pedis artery
Dorsalis Pedis Artery[edit]
The dorsalis pedis artery is a blood vessel of the lower limb. It is a continuation of the anterior tibial artery and is located on the dorsum of the foot. This artery plays a crucial role in supplying blood to the foot and is often used clinically to assess the vascular status of the lower extremity.
Anatomy[edit]
The dorsalis pedis artery begins at the level of the ankle joint, as the anterior tibial artery crosses the ankle. It runs along the dorsal aspect of the foot, towards the first intermetatarsal space, where it divides into the first dorsal metatarsal artery and the deep plantar artery.
Course[edit]
The artery travels superficially, lying just beneath the skin and fascia, making it easily palpable in most individuals. It runs alongside the extensor hallucis longus tendon and is accompanied by the deep peroneal nerve.
Branches[edit]
The dorsalis pedis artery gives off several branches, including:
- The lateral tarsal artery
- The arcuate artery
- The first dorsal metatarsal artery
- The deep plantar artery
These branches contribute to the blood supply of the dorsal aspect of the foot and the toes.
Clinical Significance[edit]
The dorsalis pedis artery is commonly used in clinical practice to assess the peripheral circulation of the lower limb. The pulse of the dorsalis pedis artery can be palpated on the dorsum of the foot, lateral to the extensor hallucis longus tendon. Absence or diminution of this pulse can indicate peripheral vascular disease or other circulatory problems.
