Superficial thrombophlebitis is a thrombosis and inflammation of superficial veins presenting as a painful induration (thickening) with erythema, often in a linear or branching configuration with a cordlike appearance. [2]: 826–7 [3] Superficial thrombophlebitis is due to inflammation and/or thrombosis, and, less commonly, infection of the vein.
A list of veins in the human body: Veins of the heart. Coronary sinus. Great cardiac vein; Oblique vein of left atrium; Middle cardiac vein; Small cardiac vein
[nb 3] [23] A shunting of blood from the thigh veins back into the lower-leg veins produces a reflux situation. The veins most often found to be incompetent are the saphenous veins and the perforators communicating with the deep veins of the thigh. [24]
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.
Veins become more visually prominent when lifting heavy weight, especially after a period of proper strength training. Physiologically, the superficial veins are not as important as the deep veins (as they carry less blood) and are sometimes removed in a procedure called vein stripping, which is used to treat varicose veins.
In the same population, deep vein thrombosis (DVT) was found in 24.6% of people with SVTs. [3] However, because superficial veins lack muscular support, any clots that form are far less likely to be squeezed by muscle contraction, dislodged, and induce a PE. [2] SVTs can recur after they resolve, which is termed "migratory thrombophlebitis."
Telangiectasia in the legs is often related to the presence of venous reflux within underlying varicose veins. Flow abnormalities in smaller veins known as reticular veins or feeder veins under the skin can also cause spider veins to form, thereby making a recurrence of spider veins in the treated area less likely.
The veins of the arm carry blood from the extremities of the limb, as well as drain the arm itself. The two main veins are the basilic and the cephalic veins. There is a connecting vein between the two, the median cubital vein, which passes through the cubital fossa and is clinically important for venepuncture (withdrawing blood).
