Group of arteries which are placed relatively close the thigh’s 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 hunter’s canal. Femoral artery branches out to provide blood to tissues and muscles which are located in the thigh’s superficial region.The common femoral artery is about 4 cm in length and divides into the superficial femoral and the profunda femoris arteries.
This artery starts immediately from the backside of inguinal ligament and travels in between the ilium’s anterior spine and symphysis and extends up to the front as well as the medial side of thigh. The point where both middle and lower third thigh join together, femoral artery ends and from here it opens up inside the Adductor magnus and is called as popliteal artery. This place is known as the femoral head. The arteries upper third part is placed in femoral triangle known as Scarpa’s triangle while its middle third part is placed in Hunter’s canal.
The blood to the femoral artery is provided by external iliac artery which is placed within the femoral triangle and just at the back of inguinal ligament and very near to femur bone head. This whole area is termed as inguinal femoral area. The inguinal ligament serves as the triangle border at the superior end, medial border is formed by addustor longus and the satorious muscle forms the lateral border. The topmost triangle area is composed of subcutaneous tissue, skin, cribiform fascia and fascia lata whereas the bottom part is made up of ilioposoas muscles.
One of the regular femoral artery called as Common femoral artery or CFA is placed at the proximal section of formal artery and is majorly used as artery for catheter access because it is very easily felt beneath the skin. Clinically it is used to draw arterial blood during low blood pressure problem as the radial or arterial arteries can’t be located during low blood pressure. When the femoral artery leaves the triangle via apex just beside the sartorious muscle it branches itself into superficial and deep artery termed as superficial femoral artery or SFA. 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.
Some of the common forms of disorders associated with femora artery are :
