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 ...
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.
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.
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]
DVT often develops in the calf veins and "grows" in the direction of venous flow, towards the heart. [42] [103] DVT most frequently affects veins in the leg or pelvis [9] including the popliteal vein (behind the knee), femoral vein (of the thigh), and iliac veins of the pelvis.
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.
DVT usually occurs in the veins of the legs, although it can also occur in the veins of the arms. Immobility, active cancer, obesity, traumatic damage and congenital disorders that make clots more likely are all risk factors for deep vein thrombosis. It can cause the affected limb to swell, and cause pain and an overlying skin rash.
A venous ulcer tends to occur on the medial side of the leg, typically around the medial malleolus in the 'gaiter area' whereas arterial ulcer tends to occur on lateral side of the leg and over bony prominences. A venous ulcer is typically shallow with irregular sloping edges whereas an arterial ulcer can be deep and has a 'punched out' appearance.
