Unilateral atypical disposition of femoral vessels: clinico- embryological annotations

The boundaries and contents of femoral triangle constitute an important lesson in gross anatomy teaching to undergraduate medical students. Apart from this, the normal disposition of the femoral vessels in the femoral triangle is vital for planning certain operating maneuvers in this region. Femoral vessels are very frequently utilized, during various surgical and clinical procedures. Thus, the precise knowledge of the normal anatomy as well as the variations in the femoral vessels is important for surgeons and anatomists. We report a unilateral variation in the disposition of femoral vessels in the femoral triangle, in a 42 yr old male formalin- preserved cadaver. The femoral artery traversed anterior to femoral vein to occupy a medial position in close proximity to the Sapheno-femoral junction. The embryological and clinical implications of the observed variation are discussed.
