Bilateral Variation in the Origin of Circumflex Femoral Arteries: Anatomical Insights and Clinical Implications.

The medial circumflex femoral artery (MCFA) and lateral circumflex femoral artery (LCFA) are crucial in providing blood supply to the hip and femoral head region and the adductor and extensor compartments of the thigh. This case report aims to document a rare bilateral variation in the origin of MCFA and LCFA observed during a routine cadaveric dissection in an anatomy lab. In a male donor aged approximately 78 years, the MCFA on the left side originated from the profunda femoris artery (PFA), whereas the LCFA arose from the femoral artery (FA). On the right side, the MCFA originated from the FA, while the LCFA had a typical origin from the PFA. These arterial variations were measured with reference to standard anatomical landmarks. Awareness of such variations can help clinicians avoid complications during procedures involving the FA and PFA.
