The femoral triangle (or Scarpa's triangle) is an anatomical region of the upper third of the thigh. It is a subfascial space which appears as a triangular depression below the inguinal ligament when the thigh is flexed, abducted and laterally rotated.

The femoral vein continues into the thigh as the continuation from the popliteal vein at the back of the knee. It drains blood from the deep thigh muscles and thigh bone. [2] Proximal to the confluence with the deep femoral vein, and the joining of the great saphenous vein, the femoral vein is widely known as the common femoral vein. [3]
They lie deep to the fascia of Camper that overlies the femoral vessels at the medial aspect of the thigh. They are bounded superiorly by the inguinal ligament in the femoral triangle, laterally by the border of the sartorius muscle, and medially by the adductor longus muscle. There are approximately 10 superficial lymph nodes.
Its upper portion forms the lateral border of the femoral triangle, and the point where it crosses adductor longus marks the apex of the triangle. Deep to sartorius and its fascia is the adductor canal, through which the saphenous nerve, femoral artery and vein, and nerve to vastus medialis pass. [3]
The femoral artery gives off the deep femoral artery and descends along the anteromedial part of the thigh in the femoral triangle. It enters and passes through the adductor canal , and becomes the popliteal artery as it passes through the adductor hiatus in the adductor magnus near the junction of the middle and distal thirds of the thigh.
Just inferolateral to the pubic tubercle the fascia extends downwards forming an arched (falciform) margin of the lateral boundary of the opening. It is covered by a thin perforated part of the superficial fascia called the fascia cribrosa which is pierced by the great saphenous vein, the 3 superficial branches of the femoral artery (except superficial circumflex iliac artery, which pierces ...
