Abstract

Background: The development of the  arterial system of the lower limb is very complex and is prone to anatomical variations. In the world, there have been many studies on the variation of the dorsalis pedis artery. But in Vietnam, there have been no studies reporting on the variations as well as the abnormal origin of the dorsal artery. Objective: To report a rare case of continuation of the peroneal artery and joined with the anterior tibial artery to form the dorsalis pedis artery in the foot. 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: During the implementation of the topic "Study on some anatomical features of the dorsalis pedis artery in Vietnamese people", we dissected 15 cadavers (30 lower limbs) treated with formalin, in which 2 cases were recorded. A right lower limb of a 72-year-old female sex carcass code 605 and a left lower limb of a 60-year-old male carcass code 581 has a rare anatomical variant not currently reported in Vietnam. In this case, the origin of the dorsalis pedis artery came from the fusion of the anterior tibial artery and the peroneal artery instead of the anterior tibial artery as in the literature. Conclusion: The present arterial variation around the ankle is important to radiologists, vascular and orthopedic surgeons in surgical operative techniques and interpretation of imaging study. Therefore, preoperative angiography to investigate the anatomical variations in the path and distribution of the dorsalis pedis artery is necessary to avoid unnecessary risks.
