Anterior accessory saphenous vein. The anterior accessory saphenous vein is a special anterior tributary of the great saphenous vein (GSV), draining the antero-lateral face of the thigh. It becomes very often insufficient, causing important varicose veins with an autonomous course and often is the only insufficient vein present on a patient.
Perforator veins are so called because they perforate the deep fascia of muscles, to connect the superficial veins to the deep veins where they drain. [1][2] Perforator veins play an essential role in maintaining normal blood draining. They have valves which prevent blood flowing back (regurgitation) from deep to superficial veins in muscular ...
The popliteal vein is a vein of the lower limb. It is formed from the anterior tibial vein and the posterior tibial vein. It travels medial to the popliteal artery, and becomes the femoral vein. It drains blood from the leg. It can be assessed using medical ultrasound. It can be affected by popliteal vein entrapment.
21376. Anatomical terminology. [edit on Wikidata] The great saphenous vein (GSV) or long saphenous vein (/ səˈfiːnəs /) is a large, subcutaneous, superficial vein of the leg. It is the longest vein in the body, running along the length of the lower limb, returning blood from the foot, leg and thigh to the deep femoral vein at the femoral ...
The leg, then, must rely on the superficial venous system for drainage. The superficial system is not adequate to handle the large volume of blood being delivered to the leg via the arterial system. The result is edema, pain and a white appearance (alba) of the leg. The next step in the disease progression is occlusion of the superficial venous ...
The veins have now become varicose veins, and from this additional blood, they start becoming tortuous, or twisted. This most commonly affects the superficial veins on the surface of legs, since they see high pressures when standing, rather than the deep veins buried inside the muscles. Oftentimes, though, collateral veins are used instead ...
In humans, the cisterna chyli is located posterior to the abdominal aorta on the anterior aspect of the bodies of the first and second lumbar vertebrae (L1 and L2). There it forms the beginning of the primary lymph vessel, the thoracic duct, which transports lymph and chyle from the abdomen via the aortic opening of the diaphragm up to the junction of left subclavian vein and internal jugular ...
The "arch of the azygos vein" (arcus venae azygos) is an important anatomic landmark. As an anatomical variation in 1–2% of the population, the arch can be displaced laterally, thereby creating a pleural septum separating an azygos lobe from the upper lobe of the right lung. The origin and anatomical course of the azygos vein are quite variable.
