The femoral triangle is a hollow region in the anterior thigh that contains neurovascular structures and lymph nodes. It is used for palpation, ultrasound, and vascular access in various medical procedures. The femoral triangle is a subfascial space in the upper third of the thigh, bounded by the inguinal ligament, adductor and sartorius muscles. It contains vital structures such as the femoral nerve, artery, vein, lymph nodes and branches of the genitofemoral nerve. Each of these is obviously enclosed in one, big femoral sheath. The femoral nerve lies outside the femoral sheath. A way of remembering the contents of the femoral triangle is the mnemonic NAVY – nerve, artery, vein y-fronts (as in briefs or pants, whatever, underwear for men). Nerve, artery, vein from lateral to medial. Femoral triangle is a superficial triangular space located on the anterior aspect of the thigh just inferior to the inguinal ligament .
