The saphenous opening refers to an anatomical structure found in the lower limb, specifically in the groin region, within the thigh. It is a small, oval-shaped aperture located within the fascia lata, a strong connective tissue layer enveloping the thigh muscles. The saphenous opening is situated just below and lateral to the pubic tubercle, near the femoral triangle.
The saphenous opening serves as a passageway for the greater saphenous vein, the longest vein in the body, to exit the lower limb and enter the abdominal cavity. This vein arises from the medial side of the foot and ascends along the inner leg, draining blood from the superficial tissues of the lower limb. As it approaches the groin, the greater saphenous vein traverses the saphenous opening, entering the femoral vein and eventually reaching the circulatory system of the body.
In addition to providing an opening for the greater saphenous vein, the saphenous opening also contains other structures, including lymphatic vessels and smaller veins. These structures help facilitate the return of lymphatic fluid and venous blood from the lower limb. The saphenous opening is of clinical importance in surgical procedures, such as hernia repair, as it allows access to the femoral region and provides a landmark for identifying anatomical structures during the surgery.
Fossa ovalis, an oval aperture in the fascia in the upper and inner part of the thigh below Poupart's ligament, which transmits the internal saphenous vein.
