However, there are two exceptions: firstly, the GSV collaterals (the veins that run parallel) drain the abdominal wall and have a flow from top to bottom so that, when an examiner tests the saphenofemoral junction, a false-positive diagnosis might be made; secondly, in the flow from the sole of the foot venous network, around 10% drains to the ...
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]
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.
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.
Muscle action is needed not only to keep blood flowing through the veins but also to stimulate the lymphatic system to fulfil its "overflow" function. Long-haul flights, lengthy bed-rest, immobility caused by disability and so on, are all potential causes of water retention.
Varicose veins are veins that have become enlarged and twisted, especially within the legs, ankles and feet of an affected individual. [4] When standing, gravity pulls the blood downwards to the lower part of the body. Body mechanisms, such as vasoconstriction and valves of the veins, assist in pumping blood upwards. [5]
A migraine attack can be a debilitating condition. But a headache is just one part. There are other subtle warning symptoms to watch out for, neurologists say.
Vascularity, in bodybuilding, is the condition of having many highly visible, prominent, and often extensively-ramified superficial veins. [1] The skin appears "thin"—sometimes virtually transparent—due to an extreme reduction of subcutaneous fat, allowing for maximum muscle definition. [citation needed]
