Varicose veins are unlikely to be caused by crossing the legs or ankles. [17] Less commonly, but not exceptionally, varicose veins can be due to other causes, such as post-phlebitic obstruction or incontinence, venous and arteriovenous malformations. [18] Venous reflux is a significant cause. Research has also shown the importance of pelvic ...
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]
Prolonged standing increases the risk for hospitalization from varicose veins. [6] Among the working age population one out of five hospitalizations from varicose veins are as a result of prolonged standing. Prolonged standing leads to impeded blood flow and stasis in the veins in the lower limbs, which can cause varicose veins.
If blood travels too slowly and starts to pool in the leg veins, the pressure can force too much fluid out of the leg capillaries into the tissue spaces. The capillaries may break, leaving small blood marks under the skin. The veins themselves can become swollen, painful and distorted – a condition known as varicose veins. [17]
Causes [2] of venous stasis include: Obesity; Pregnancy; Previous damage to leg; Blood clot; Smoking; Swelling and inflammation of a vein close to the skin; Congestive heart failure. [3] Long periods of immobility that can be encountered from driving, [4] flying, bed rest/hospitalization, or having an orthopedic cast.
This textbook provides essential information on the cause, presentation and up-to-date management of venous diseases. It also includes important data on prevention and treatment of blood clots, leg swelling, varicose veins and venous ulcers. [8]
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]
Causes: Chronic venous insufficiency, varicose veins, traumatic damage to vascular walls, genetics: Treatment: Ligation of leaking veins, lifestyle changes: Frequency: Arterial insufficiency: Younger than 45 years old - 12% Older than 45 years old - 19.6% (mild), 5.9% (severe) Venous leakage: 7.84% (of 67 patients) [1]
