Medial circumflex artery (lat. A. circumflexa femoris medialis, PNA, BNA)

The medial femoral circumflex artery is an artery in the human body that curves around the femur and runs along the medial surface of the thigh. It is a branch of the external iliac artery, which arises from it at the level of the inguinal ligament.

Anatomically, the circumflex femoral artery is divided into two parts:

  1. The upper part runs along the lateral surface of the thigh, then moves to the medial surface and goes around the femur.
  2. The lower part runs down the medial side of the thigh and ends at the knee.

The function of the circumflex femoral artery is to supply blood to the muscles and skin on the medial side of the leg and to supply blood to the femur and joints.

With pathology of the circumflex femoral artery, various diseases associated with impaired blood supply may occur. For example, when the lumen of an artery narrows or is blocked by a blood clot, ischemia of the muscles and skin may develop, which leads to impaired function and pain.

To diagnose pathology of the femoral circumflex artery, various research methods are used, such as ultrasound, angiography and magnetic resonance imaging. Treatment depends on the cause of the disease and may include surgery, medication, or other treatments.



The artery bends around the femur medially (A.circumflexa femori medialis).

This artery supplies the lower thigh or groin area (femur inferum or regio pudenda). In the anatomical description, it is designated as a.comitans (adnexal) and a.circumductrix (envelope), which indicates its function. It originates from the femoral artery (a. femoralis), which in turn is a branch of the aorta. A.femoral
