The posterior tibial artery normally arises from tibial-fibular trunk at the popliteal fossa, together with the fibular artery. The classic course of the posterior tibial artery is to run between the triceps surae muscle and muscles of the posterior compartment of the leg before continuing its course posteriorly to the medial malleolus, while the fibular artery runs through the lateral margin of the leg. Studies of both arteries are relevant to the fields of angiology, vascular surgery and plastic surgery. To the best of our knowledge, we report the first case of an anastomosis between the posterior tibial artery and the fibular artery in their distal course. The two arteries joined in an unusual "X" format, before division of the posterior tibial artery into plantar branches. We also provide a literature review of unusual variations and assess the clinical and embryological aspects of both arteries in order to contribute to further investigations regarding these vessels.
胫后动脉通常与腓动脉一起，在腘窝处起自胫腓干。胫后动脉的经典走行是在小腿三头肌和小腿后群肌之间下行，然后继续向后至内踝后方，而腓动脉则走行于小腿外侧缘。对这两条动脉的研究与血管学、血管外科和整形外科领域相关。据我们所知，我们报告了首例胫后动脉和腓动脉在其远端走行处吻合的病例。两条动脉以不寻常的“X”形相连，然后胫后动脉再分为足底分支。我们还对异常变异进行了文献综述，并评估了这两条动脉的临床和胚胎学方面，以促进对这些血管的进一步研究。
