Cadaveric Study of Angiosomes of Anterior Tibial and Dorsalis Pedis Artery

Abstract

Introduction Angiosome formed by Anterior tibial artery and dorsalis pedis artery supply the ankle and the dorsum of foot. Both the vessels shows variation in termination and branching pattern. Materials and Methods 50 free formalin preserved limbs were dissected for the study. Results and Conclusion Anterior tibial artery showed variation in termination in 16%, most common of them was formation of loop with perforating branch of peroneal artery in 10%, bifurcation in to medial and lateral tarsal artery in 4% and trifutcation in 2%. Branching pattern of dorsalis pedis artey was variable in 18%, medial and lateral tarsal arteries were not branches of dorsalis pedis artery in 14% and 16% respectively. Arcuate artery was absent in 10%, when present it was branch of dorsalis pedis artery in 96%, perforating branch of peroneal artery in 2% and loop of medial and lateral tarsal artery in 2%. First dorsal metatarsal artery was not branch of dorsalis pedis artery in 4%. Lateral tarsal artery was constantly found in all the dissected limbs. Thorough knowledge of variation about branching pattern of arterial tree is clinically important for accuracy in interpretation of angiographs, Doppler study of lower limb vessels and optimum use of vascular pedicle for myocutaneous flaps. Importance of palpation of peripheral pulse in lateral tarsal artery is discussed in the study.

Features of the Extraction of the Anterior Tibial Vessels in the Formation of Vascularized Bone Grafts

“…По данным литературы, формирование переднего большеберцового и трансплантата 2-й плюсневой кости и их ротация невозможны при редких анатомических вариантах строения: отсутствии ПБА [11,12,13], отсутствии артерии тыла стопы, начале артерии тыла стопы от малоберцовой артерии [14] или задней большеберцовой артерии [15,16]. Так, по данным В. Adachietal, в 7,1% наблюдений ПБА отсутствует [13].…”

Sonographic anatomy and imaging of the dorsal supportive ligaments of the Chopart joint complex

“…A helpful sonographic landmark to assist identification of this medial band is the lateral tarsal artery and the associated motor lateral branch of the deep peroneal nerve. The lateral tarsal artery is a lateral branch of the dorsalis pedis artery which sit deep to the extensor hallucis brevis muscle (EHBm) 34,35 . The EHBm sits medial to the EDBm and originates from the dorsolateral aspect of the calcaneus and inserts onto the dorsal base of the proximal phalanx of the great toe.…”

“…The EHBm sits medial to the EDBm and originates from the dorsolateral aspect of the calcaneus and inserts onto the dorsal base of the proximal phalanx of the great toe. The calcaneonavicular band of the bifurcate ligament sits deep to the lateral tarsal artery and EHBm 33,34 …”

“…The calcaneonavicular band of the bifurcate ligament sits deep to the lateral tarsal artery and EHBm. 33,34 It can be difficult sonographically to discern the echogenic calcaneonavicular band of the bifurcate ligament as separate from the deeper sinus tarsi fat when using perpendicular sound incidence.…”
