Duplicated or Divided Fibular Artery in Lower Limb Vascularization: Anatomical Variations and Clinical Implications

Author(s): Sayuri Nakamura

The fibular artery, a branch of the posterior tibial artery, plays a crucial role in the vascularization of the lower limb, supplying blood to the muscles and structures of the lateral compartment of the leg, as well as contributing to the foot and ankle circulation. Variations in the anatomy of the fibular artery, such as duplication or division, are relatively uncommon but have significant implications for clinical practice, especially in the context of surgical procedures, traumatic injuries, and vascular pathologies. This article examines the anatomical variations of the fibular artery, particularly its duplication or division, and discusses the clinical and surgical implications of these variations for lower limb vascularization. Understanding these variations is essential for improving diagnostic accuracy and optimizing surgical outcomes in procedures involving the lower limb vasculature.
