- Abstract: The common femoral artery (CFA) typically gives rise to its superficial and deep branches, with the deep femoral artery (DFA) being the largest and most substantial of these branches. This case study presents a rare variation of the DFA characterized by an unusual branching pattern and its specific relationship with the femoral vein within the subinguinal region. In nutshell, the DFA and the medial femoral circumflex artery shared a common origin from the medial aspect of the CFA. The DFA assumed an unusual course, initially passing anterior to the femoral vein above the saphenofemoral junction, followed by a spiraling trajectory around the medial aspect of the femoral vein before running posteriorly. The embryological origins and clinical implications of this anatomical variation are thoroughly examined. This unusual vascular relationship in the subinguinal region may potentially result in arterial injury during femoral vein cannulation or formation of arteriovenous fistula after the procedure.
