Also, unlike ultrasonography of deep venous thrombosis, the procedure focuses mainly on superficial veins. Also, unlike the arterial ultrasound examination, blood velocity in veins has no diagnostic meaning. Veins are a draining system similar to a low pressure hydraulic system, with a laminar flow and a low velocity.
If the impaired vein function causes significant symptoms, such as swelling and ulcer formation, it is referred to as chronic venous disease. [3] It is sometimes called chronic peripheral venous insufficiency and should not be confused with post-thrombotic syndrome in which the deep veins have been damaged by previous deep vein thrombosis.
Minor compression of the inferior vena cava during pregnancy is a relatively common occurrence. It is seen most commonly when women lie on their back or right side. [4] 90% of women lying in the supine position during pregnancy experience some form of inferior vena cava syndrome; however, not all of the women display symptoms. [4]
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] Pain in the legs or lower back may also occur. [1]
Weakened Venous valves: these are crucial towards ensuring upward flow to the heart from the lower extremities. If weakened, they may fail to close properly which leads to backwards blood flow/blood pooling. This can lead to slower blood flow in the veins. [8] Ultrasonography-Doppler ultrasound
Because of its similarities to deep vein thrombosis (DVT), May–Thurner syndrome is rarely diagnosed amongst the general population. In this condition, the right iliac artery sequesters and compresses the left common iliac vein against the lumbar section of the spine, [5] resulting in swelling of the legs and ankles, pain, tingling, and/or numbness in the legs and feet. [6]
Some people don’t experience any symptoms at all. Symptoms common in several types of cardiovascular disease include: Shortness of breath. Chest pain. Fatigue. Dizziness. Fainting. Fever ...
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 ...
