Abstract

Objective: To determine the number, diameter, and location of the branches of the dorsalis pedis artery in relation to surrounding anatomical landmarks. Subjects and method: A descriptive series study conducted on adult Vietnamese cadavers with intact dorsum of the foot, preserved with formalin, at the Department of Anatomy, University of Medicine and Pharmacy at Ho Chi Minh City. Results: Among the 15 cadaveric specimens, there were 9 males and 6 females, with an average age of 69.9 ± 8.9 years (range: 57–91 years). The maximum number of medial tarsal arteries observed was 3, while the minimum was 1. The origins of these arteries were variable, ranging from 4.2–57.8 mm from the ankle joint, with branch diameters of approximately 1 mm. The maximum number of lateral tarsal arteries observed was 4, while the minimum was 1. The distance from the origins to the ankle joint ranged from 2.8–64.1 mm, with branch diameters ranging from 1–1.5 mm. The arcuate artery was present in only 16.7% of cases, with an average diameter of 1.3 ± 0.3 mm. The average diameter of the deep plantar artery was 1.6 ± 0.4 mm, and that of the first dorsal metatarsal artery was 1.5 ± 0.4 mm. Conclusion: Surgeons should evaluate the dorsalis pedis artery using vascular ultrasound or angiography prior to surgery, as abnormalities in the origin, course, and branching of the dorsalis pedis artery are relatively common and complex.
