case_images: Typical anatomy of the origin of the LCFA. The LCFA typically arises from the DFA with its three branches: ascending, transverse, and descending. LCFA: lateral circumflex femoral artery; DFA: deep femoral artery. Image Credits: Megan E. Gremillion

case_images: Conventionally, the LCFA stems from the DFA, dividing into ascending, transverse, and descending branches, as shown in Figure 1.
case_images: Femoral triangle of the right leg of an elderly male cadaver. Duplicated LCFAs (A and B), CFA (C), DFA (D), MCFA (E), duplicated ascending branches (F and G), duplicated transverse branches (H and I), and duplicated descending branches (J and K) are shown.. LCFA: lateral circumflex femoral artery; CFA: common femoral artery; DFA: deep femoral artery; MCFA: medial circumflex femoral artery

case_images: Moreover, the duplicated LCFAs originated from disparate sites, as evident in Figure 2 and Figure 3: the first LCFA (A) arose superiorly from the CFA (C) and the second LCFA (B) originated inferiorly from the DFA (D). Additionally, as depicted in Figure 2 and Figure 3, the CFA gave rise to the MCFA (E), responsible for femoral head vascularization in conjunction with the LCFA, exhibiting a typical course in this particular specimen.
case_images: Duplication of the LCFA and its branches.  LCFA 1 arising from the DFA being the typical course, and LCFA 2 being the abnormal duplication emerging from the CFA. LCFA: lateral circumflex femoral artery; DFA: deep femoral artery; CFA: common femoral artery. Image Credits: Megan E. Gremillion
