[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
Venography (also called phlebography or ascending phlebography) is a procedure in which an X-ray of the veins, a venogram, is taken after a special dye is injected into the bone marrow or veins. The dye has to be injected constantly via a catheter, making it an invasive procedure.
Pelvic congestion syndrome, also known as pelvic vein incompetence, is a long-term condition believed to be due to enlarged veins in the lower abdomen. [ 1 ] [ 7 ] The condition may cause chronic pain , such as a constant dull ache, which can be worsened by standing or sex. [ 1 ]
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]
Absence of the portal system in a first trimester case associated with hygroma and aorto-umbilical fistula. (A): Transverse plane of the upper abdomen with color Doppler applied, showing umbilical cord insertion, stomach, the prominent hepatic artery and no afferent liver venous perfusion; (B): midsagittal plane reconstructed from a three-dimensional volume acquisition were the crown-rump ...
