Deep vein thrombosis (DVT) is a type of venous thrombosis involving the formation of a blood clot in a deep vein, most commonly in the legs or pelvis. [9] [a] A minority of DVTs occur in the arms. [11] Symptoms can include pain, swelling, redness, and enlarged veins in the affected area, but some DVTs have no symptoms. [1]
Deep vein thrombosis (DVT) is the formation of a blood clot within a deep vein. It most commonly affects leg veins, such as the femoral vein. Three factors are important in the formation of a blood clot within a deep vein—these are: the rate of blood flow, the thickness of the blood and; qualities of the vessel wall.
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. Upper extremity PCD is less common, occurring in under 10% of all cases. [1]
For example, the superficial venous system (SVS) can be very well examined using a high-frequency probe of 12 MHz. For patients who have thick adipose tissue, a probe of 7.5 MHz will be required. Deep veins require probes of around 6 MHz, while the abdominal vessels are better studied with probes of between 4 and 6 MHz. [9]
Deep vein thrombosis/ right leg Thrombophlebitis causes include disorders related to increased tendency for blood clotting and reduced speed of blood in the veins such as prolonged immobility; prolonged traveling (sitting) may promote a blood clot leading to thrombophlebitis but this occurs relatively less.
This valvular incompetence combined with persistent venous obstruction from thrombus increases the pressure in veins and capillaries. Venous hypertension induces a rupture of small superficial veins, subcutaneous hemorrhage [7] and an increase of tissue permeability. That is manifested by pain, swelling, discoloration, and even ulceration. [8]
Chronic venous insufficiency (CVI) is a medical condition characterized by blood pooling in the veins, leading to increased pressure and strain on the vein walls. [1] The most common cause of CVI is superficial venous reflux, which often results in the formation of varicose veins, a treatable condition. [2]
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] As the common femoral vein leaves the inguinal ligament region it becomes the external iliac vein. [4]
