Abstract：
Studies reveal variations in the in the origin, number, and branching patterns of the lateral circumflex femoral artery (LCFA). The present study aimed to document such variations and their potential clinical applicability. Thirty-two femoral 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 in branching 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 the femoral artery (CFA). Duplication LCFA was observed in 15 (46.87%) limbs, in 5 (31.25%) cases duplication was only on right side, in 4 (25%) cases duplication was only on left side and in 3 (18.75%), duplication was bilateral. Cases with duplication of LCFA, showed numerical variations with descending pattern being the most common. The average distance of LCFA1 and LCFA2 from mid-inguinal point was 5.77±1.35 cm and 6.14±2.05 cm respectively. Detailed information regarding the occurrence of duplication will be great importance for surgeons, interventional radiologists, and other medical professionals performing procedures in the femoral region. Knowledge of variation of branching pattern of LCFA is utmost important as surgeons use the descending branch of the LCFA in bypass grafting and vascular reconstruction surgeries.
摘要：
研究揭示了起源的变化，number,和旋股外侧动脉（LCFA）的分支模式。本研究旨在记录这些变化及其潜在的临床适用性。解剖了16具经过防腐处理的成年人尸体的32个股骨三角形，以研究起源的变化，number,和LCFA的分枝模式。独立跟踪LCFA的主要分支，以了解分支模式的数值变化。在每种情况下还测量了LCFA的起点与腹股沟中点(MIP)之间的距离。LCFA最常见于股骨深部(PF)，其次是股动脉（FA）和股动脉共同干（CFA）。在15（46.87％）肢体中观察到复制LCFA，在5例(31.25%)中，重复仅在右侧，在4例（25％）中，重复仅在左侧，在3例（18.75％）中，重复是双边的。LCFA重复的案件，显示出数值变化，下降模式是最常见的。LCFA1和LCFA2距腹股沟中点的平均距离分别为5.77±1.35cm和6.14±2.05cm。关于重复发生的详细信息对于外科医生来说非常重要，介入放射科医生,和其他医疗专业人员在股骨区域执行手术。了解LCFA分支模式的变化至关重要，因为外科医生在旁路移植术和血管重建手术中使用LCFA的下降分支。
