Dorsalis Pedis Artery

Pedal arterial anatomy can be divided into the anterior circulation, the posterior circulation, and the pedal arches, which connect the two circulations (Figs. 1-3). The anterior circulation consists of the

7 Plantar metatarsal arteries dorsalis pedis artery, the medial and lateral tarsal arteries, the arcuate artery, and the deep plantar (or perforating) artery. These vessels are all quite small, with the dorsalis pedis artery being 2.0 - 3.0 mm in diameter [20]. The posterior circulation begins as the distal posterior tibial (or common plantar) artery, bifurcating into the medial and lateral plantar arteries. The lateral plantar artery continues as the plantar arch, which anastomoses to the deep plantar artery, thereby forming the primary pedal arch. The first dorsal metatarsal artery is the largest artery off of the primary arch, being 1.0 to 1.5 mm in diameter [20]. Secondary arches may form via

(b) the dorsalis pedis, the medial tarsal, the medial plantar, and common plantar arteries, or

(c) dorsalis pedis, arcuate artery, lateral plantar, and common plantar arteries (Figs. 2,3).

In imaging, non-filling of one of these named segments cannot be considered definitive occlusion unless clearly opacified unnamed pedal vessels and collaterals are seen along its course [10].

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
