During routine dissection, of the lower limb of a 70 year old donated embalmed male cadaver in the Department of Anatomy, at K.J. Somaiya Medical College, Sion, Mumbai, India, I observed two dorsalis pedis arteries arising from the anterior tibial artery in the lower part of the leg. Both the dorsalis pedis arteries travelled together on the dorsum of the foot up to the proximal part of the first intermetatarsal space. The pattern of nerves in the leg was normal. The variation was unilateral. The photographs of the double dorsalis pedis arteries of right lower limb were taken for proper documentation. Clinical Significance. The awareness of knowledge of any variation in dorsalis pedis arteries is clinically important for surgeons, plastic surgeons and orthopaedicians because the dorsalis pedis artery is used to record peripheral arterial pulsation. Non-healing diabetic foot ulcers which are challenging problems for surgeons, are commonly dealt with by musculocutaneous flaps based on the branches of dorsalis pedis artery. These musculocutaneous flaps are commonly used in reconstructive surgeries. A lack of knowledge of variations the dorsalis pedis arteries might complicate surgical repair.
