Veins of the lower limb. Valves in superficial veins of the lower extremity usually are located near to the termination of major tributaries.

Additionally ultrasound is used to guide endovenous procedures such as foam sclerosant injection endovenous laser therapy evlt or radiofrequency ablation rfa for the treatment of superficial venous disease.
Lower extremity vein anatomy. The superficial veins which are above the deep fascia and drain the cutaneous microcirculation. Deep superficial and perforating veins. The venous system of the lower extremities includes the deep veins which lie beneath the muscular fascia and drain the lower extremity muscles.
In us examination of the lower extremity veins knowledge of the venous anatomy as well as appropriate patient positioning and transducer placement are important for optimal imaging and accurate diagnosis. The lower extremity venous anatomy is divided into three interconnected systems. The veins rely on a more passive and indirect mechanism to help aid in the return of blood to the heart.
And the perforating veins that penetrate the muscular fascia and connect the superficial and deep veins. The venous system of the lower extremities is divided into three groups. The deep veins accompany the major arteries and their branches and are usually paired.
Lower extremity venous anatomy. The lower limb consists of two main types of veins. Lower limb venous duplex imaging can be used for the assessment of patients with primary or recurrent varicose veins or for the investigation of patients with skin changes and venous ulceration.
In the pelvis and lower extremities blood in the veins has to fight gravity in order to flow in the correct direction. Some valves are well developed with marked sinusoid dilation at their base others are more delicate in their structure. The superficial veins are located within the subcutaneous tissue whilst the deep veins are found deep to the deep fascia.
Inguinal perforators drain into the femoral vein in the proximal thigh.
