Hypoplastic Anterior Tibial Artery Associated with Continuation of Fibular (Peroneal) Artery as Dorsalis Pedis Artery. A Case Report Arteria Tibial Anterior Hipoplásica Asociada con la Continuación de la Arteria Fibular como Arteria Dorsal del Pié. Un Reporte de Caso

continuationof fibular (peroneal) artery as dorsalis pedis artery. A case report. Int. J. Morphol., 31(1):136-139, 2013.SUMMARY: Arterial variations of distal parts of lower limb are well documented. However, continuation of fibular artery asdorsalis pedis artery is a rare finding. Unusual course and distribution of the anterior tibial artery and fibular artery were observed duringroutine anatomical dissection of the right lower limb of an approximately 40-year-old male cadaver. The arteries of the crural regionarose from the popliteal artery, as usual. However the anterior tibial artery was hypoplastic. The fibular artery was larger th an usual andcrossed the lowest portion of the interosseous membrane and continued as dorsalis pedis artery. Posterior tibial artery had a normalcourse and distally divided into medial and lateral plantar arteries. The awareness of these variations is important to vascular surgeonswhile performing arterial reconstructions in femorodistal bypass graft procedures, and also to orthopaedic surgeons during surgicalclubfoot release.KEY WORDS: Anatomical variaton; Anterior tibial artery; Peroneal artery; Fibular artery; Dorsalis pedis artery.
