The middle image shows where varicose veins might appear in a leg. Comparison of healthy and varicose veins. Varicose veins are more common in women than in men and are linked with heredity. [16] Other related factors are pregnancy, obesity, menopause, aging, prolonged standing, leg injury and abdominal straining. Varicose veins are unlikely to ...
Chronic venous insufficiency (CVI) is a medical condition in which blood pools in the veins, straining the walls of the vein. [1] The most common cause of CVI is superficial venous reflux which is a treatable condition. [2]
For the prevention of blood clots in the general population, incorporating leg exercises while sitting down for long periods, or having breaks from a sitting position and walking around, having an active lifestyle, and maintaining a healthy body weight are recommended. [6] Walking increases blood flow through the leg veins. [152]
Blood squirt (blood spurt, blood spray, blood gush, or blood jet) is a projectile expulsion of blood when an artery is ruptured. Blood pressure causes the blood to bleed out at a rapid, intermittent rate in a spray or jet, coinciding with the pulse, rather than the slower, but steady flow of venous bleeding.
Oftentimes, though, collateral veins are used instead, which is where other veins can take the blood as an alternate pathway so it doesn’t stagnate in the varicose vein, and these tend to actually be the deep veins in the legs. Other than the legs, in men it can also occur in the scrotum (usually on the left side) where it is called a varicocele.
It is very useful when legs are painful or very edematous (swollen with fluid). [20] Flexing the toes and feet and extending on tiptoes can all be very useful in detecting perforator vein incompetence. These movements unleash a muscle contraction which compresses deep veins.
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 peripheral vascular system is the part of the circulatory system that consists of the veins and arteries not in the chest or abdomen (i.e. in the arms, hands, legs and feet). [1] [2] The peripheral arteries supply oxygenated blood to the body, and the peripheral veins lead deoxygenated blood from the capillaries in the extremities back to ...
