Abstract
Introduction: In diagnostic angiographic procedures, the knowledge of arterial variations in the femoral artery (FA), deep femoral artery (DFA) and lateral and medial circumflex femoral arteries (LCFA, MCFA) has a great impact. Material and methods: The frequency of branching patterns of these arteries was investigated in 111 thighs of body donors. Gender and side differences were analyzed statistically. Results: The median distance of separation of the DFA from the FA in relation to the inguinal ligament (IL) was 3.29 cm. High origins (1−2 cm below IL) and middle origins (3−5 cm below IL) of the DFA were found in an equal distribution of 39.3% and 41.1%, respectively. Low origins (6−10 cm below IL) were rare (19.6%) but showed a tendential significance toward expression in males (p = 0.096). The origin of the LCFA from the FA (19.8%) or DFA (70.2%) are in line with the findings of other groups. The origin of the MCFA from FA (14.4%) or DFA (74.7%) showed that circumflex femoral arteries arose mostly from DFA. A trifurcation of the FA into the DFA, LCFA and MCFA was only observed in 9.9% and, therefore, less frequently than reported by others. Branches of the femoral nerve (FN) passed mostly anterior (46.4%) or anterior and posterior (47.8%) to the LCFA. The rare constellation of branches of FN passing only posterior to the LCFA (5.8%) showed a tendential significance to left side expression (p = 0.084). Conclusions: Taken together, this is the first classification of the median distance of separation of the DFA from the FA in relation to the IL in three defined groups. The knowledge of DFA branching pattern is essential for recent therapy options of cardiac diseases using a femoral artery access: transcatheter aortic valve replacement, catheter-based miniaturized ventricular assist device and veno-arterial extracorporal membrane oxygenation. The variant topography of the branches of FN in relation to LCFA should be kept in mind when harvesting an anterolateral thigh flap.
