What is dorsalis pedis?
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.
What is the clinical significance of the dorsalis pedis artery?
The dorsalis pedis artery carries oxygenated blood to the foot. Proper blood flow is necessary for the feet to maintain proper health and mobility.
What is the right dorsalis pedis artery?
The dorsalis pedis artery, also known as the dorsal artery of the foot, is the continuation of the anterior tibial artery distal to the ankle joint. The dorsalis pedis artery gives off four branches and continues into the sole of the foot as the deep plantar artery which contributes to the deep plantar arch.
What is largest artery in the body?
Aorta Anatomy The aorta is the large artery that carries oxygen-rich blood from the left ventricle of the heart to other parts of the body.
Where does dorsalis pedis start?
The dorsalis pedis artery originates at the level of the distal tibia between the medial and lateral malleoli as the direct continuation of the anterior tibial artery 1.
How do you feel the dorsalis pedis pulse?
Pulse: Arterial Vessels of Lower Extremity
- The dorsalis pedis pulse is palpable on the dorsum of the foot in the first intermetatarsal space just lateral to the extensor tendon of the great toe.
- The posterior tibial pulse can be felt behind and below the medial malleolus.
How is the dorsalis pedis artery Perfused in the foot?
The dorsalis pedis artery perfuses the dorsal aspect of the foot with oxygenated blood. Palpating the dorsalis pedis pulse (DP pulse) of the foot can be done to evaluate on physical exam how well the foot is being perfused.
What are the branches of the dorsalis pedis?
The branches of the dorsalis pedis artery are: Lateral tarsal artery: (a. tarsea lateralis; tarsal artery) arises from the dorsalis pedis as it crosses the navicular bone. Medial tarsal artery: (aa. tarseæ mediales) are two or three small branches on the medial border of the foot and join the medial malleolar network.
What does it mean to have dorsalis pedis artery impingement?
In the meantime, a colleague of Danette’s had come across a journal article describing a case of something called dorsalis pedis artery impingement in a 17-year-old Irish dancer. The dancer also happened to have Raynaud’s disease.
What causes the lack of a dorsalis pedis pulse?
Lack of a dorsalis pedis pulse may be due to peripheral vascular disease, hypovolemia, or cardiac dysfunction. ↑ 1.0 1.1 Gray H. Anatomy of the Human Body.
