Abstract
Background: Confirming the branching pattern of the deep femoral artery (DFA) is vital in planning radiological and surgical procedures involving the medial circumflex femoral artery (MFCA) and the lateral circumflex artery (LFCA). The aim of this study was to characterise the course and morphology of branches of the DFA. Materials and methods: The anatomical dissection included 80 lower limbs which were fixed in 10% formalin solution. A dissection of the femoral region was carried out according to a pre-established protocol, using traditional techniques. Morphometric measurements were obtained twice by two researchers. Results: Six types of medial and lateral femoral circumflex artery variations were distinguished. In type I, the DFA divides into the MFCA and the LFCA (observed in 45% of cases). In type II, the MFCA is absent and the LFCA origin normally from the DFA (18.75%). In type III, the MFCA arises from the femoral artery above the origin of the DFA, while the LFCA starts from the DFA (15%). Finally, in type IV, the LFCA arises from the femoral artery above the origin of the DFA, while the MFCA starts from the DFA (10%). In type V, the LFCA origin alone from the femoral artery below the origin of the DFA, while the MFCA origin from the DFA (7.5%), while in type VI (3.75%), both the MFCA and the LFCA origin from the femoral artery. The mean diameter of the femoral artery at the level of the DFA origin was greatest in type 2 (10.62 ± 2.07 mm) and the least in type 6 (7.90 ± 1.72 mm; p = 0.0317). The distance from inguinal ligament to where the DFA arose was the greatest in type 6 (78.24 ± 29.74 mm) and least in type 5 (28.85 ± 11.72 mm; p = 0.0529). Conclusions: The medial and lateral femoral circumflex arteries were characterised by high morphological variations. The diameter of the femoral artery at the level of inguinal ligament correlated with the diameter of the DFA and distance to where the DFA arises from femoral artery.
