It can result in varicose veins and, in severe cases, in venous ulcer. The reversed blood pools in the low third of legs and feet. [17] Unlike in the arterial ultrasound study, when the sonographer studies venous insufficiency, the vein wall itself has no relevance and attention is focused on the direction of blood flow. The objective of the ...
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 ...
Venous ulcer is defined by the American Venous Forum as "a full-thickness defect of skin, most frequently in the ankle region, that fails to heal spontaneously and is sustained by chronic venous disease, based on venous duplex ultrasound testing." [1] Venous ulcers are wounds that are thought to occur due to improper functioning of venous ...
Phlegmasia cerulea dolens (PCD) (literally: 'painful blue inflammation'), not to be confused with preceding phlegmasia alba dolens, is an uncommon severe form of lower extremity deep venous thrombosis (DVT) that obstructs blood outflow from a vein.

Deep vein thrombosis (DVT), that is, blood clots in the deep veins. Chronic venous insufficiency caused by DVT may be described as postthrombotic syndrome. DVT triggers an inflammatory response subsequently injuring the vein wall. [6] Superficial vein thrombosis. Phlebitis; May–Thurner syndrome. This is a rare condition in which blood clots ...
Extensive lower-extremity DVT can even reach into the inferior vena cava (in the abdomen). [104] Upper extremity DVT most commonly affects the subclavian, axillary, and jugular veins. [11] The process of fibrinolysis, where DVT clots can be dissolved back into the blood, acts to temper the process of thrombus growth. [105] This is the preferred ...
