[25] [26] (A mapping does help the reproducibility and the inter-observer agreement of this examination.) [27] [28] The examination is made even more difficult because there can be dilated veins without insufficiency (by hyper-debit), and non-dilated but incompetent veins. Moreover, veins can be discretely incompetent in summer but normal in ...
The risk of deep vein thrombosis can be estimated by Wells score. Lower limbs venous ultrasonography is also indicated in cases of suspected pulmonary embolism where a CT pulmonary angiogram is negative but a high clinical suspicion of pulmonary embolism remains. [1] It may identify a deep vein thrombosis in up to 50% of people with pulmonary ...
A lower limbs venous ultrasonography may refer to: Ultrasonography of chronic insufficiency of the legs; Ultrasonography of deep venous thrombosis
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.
Communicating veins are veins that communicate two different points of the same venous system. Other veins that connect the superficial venous system with the deep venous system are known as perforator veins. They can communicate the great saphenous vein with the small saphenous vein, (for example the Giacomini vein). [1] [2]
The great saphenous vein (GSV) or long saphenous vein (/ s ə ˈ f iː n ə s /) 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 triangle .
The Giacomini vein or cranial extension of the small saphenous vein [1] is a communicating vein between the great saphenous vein (GSV) and the small saphenous vein (SSV). It is named after the Italian anatomist Carlo Giacomini (1840–1898). The Giacomini vein courses the posterior thigh as either a trunk projection, or tributary of the SSV.
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]
