Group of arteries which are placed relatively close the thighâs inner surface, the groin area is called Femoral artery. The origin of Femoral artery is the inguinal ligament known as Femoral Head and it moves along at a place a bit above the knee. This place is termed as Adductor or hunterâs canal.
The posterior branch of femoral artery is called as Deep femoral artery or profunda femoral artery and is the biggest femoral artery branch located within femoral triangle. Emerging from the lateral side, it travels around 3 to 5 cm below inguinal canal from where it travels further to the thigh, femur and then runs in the midst of pectineus and adductor brevis and posterior travels at the back of adductor longus.
