Reappraisal of anatomical diversity of lateral circumflex femoral artery with its substantial clinical applicability: cadaveric study

Studies reveal variations in the in the origin, number, and branching patterns of the lateral circumflex femoralartery (LCFA). The present study aimed to document such variations and their potential clinical applicability. Thirty-twofemoral triangles of 16 embalmed adult human cadavers were dissected to investigate the variation in the origin, number,and branching patterns of LCFA. The main branches of the LCFA were tracked independently for numerical variations inbranching pattern. The distance between the origin of LCFA and mid inguinal point (MIP) was also measured in each case. LCFA was most commonly arising from profunda femoris (PF), followed by femoral artery (FA) and common trunk of thefemoral artery (CFA). Duplication LCFA was observed in 15 (46.87%) limbs, in 5 (31.25%) cases duplication was only on rightside, in 4 (25%) cases duplication was only on left side and in 3 (18.75%), duplication was bilateral. Cases with duplicationof LCFA, showed numerical variations with descending pattern being the most common. The average distance of LCFA1and LCFA2 from mid-inguinal point was 5.77±1.35 cm and 6.14±2.05 cm respectively. Detailed information regarding theoccurrence of duplication will be great importance for surgeons, interventional radiologists, and other medical professionalsperforming procedures in the femoral region. Knowledge of variation of branching pattern of LCFA is utmost important assurgeons use the descending branch of the LCFA in bypass grafting and vascular reconstruction surgeries.
