Abstract

Background: The dorsalis pedis artery is the chief artery that supplies the foot and ankle area. Palpation of DPA is essential for evaluating lower limb circulation and the diagnosis of peripheral vascular diseases. Besides, cutaneous flaps supplied by branches of DPA are used in various reconstruction surgeries. Objective: Describe the variations of dorsalis pedis arteries. Methods: Study design to report a series of cases performed on 15 cadavers (30 lower limb) immersed in formol with lower extremities intact, not dissected at the Department of Anatomy - University of Medicine and Pharmacy, Ho Chi Minh City. Results: In the present study, four variations of the dorsalis pedis artery were recorded, with the typical form of the dorsalis pedis artery as described in medical books having an occurrence rate of 16.7%. Absence of arcuate artery accounts for 73.3%, lateral deviation of the dorsalis pedis artery is 3.3% and abnormal origin of dorsalis pedis artery is 6.7%. Conclusion: Variations in the anatomy and branching patterns of the dorsalis pedis artery are not rare and are clinically important, so doctors need to clearly understand the branching and course of this artery to help prepare additional steps in advance to minimize surgical complications such as when reconstruction surgeries using dorsalis pedis artery flaps or surgeries and interventional procedures in the foot area.
