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 ...
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]
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]
An unusual manifestation of NCS includes varicocele formation and varicose veins in the lower limbs. [9] Another clinical study has shown that nutcracker syndrome is a frequent finding in varicocele-affected patients and possibly, nutcracker syndrome should be routinely excluded as a possible cause of varicocele and pelvic congestion.

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.
Ultrasonography is based on the principle that sound can pass through human body tissues and is reflected by the tissue interfaces [nb 1] in the same way that light can reflect back on itself from a mirror. Tissue in the body will offer varying degrees of resistance, known as acoustic impedance, to the path of the ultrasound beam. When there is ...
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.
A medical illustration of lower extremity varicose veins. Lower extremity varicose veins is the condition in which the superficial veins become tortuous (snakelike) and dilated (enlarged) to greater than 3 mm (0.12 in) in the upright position. [24] Incompetent or faulty valves are often present in these veins when investigated with duplex ...
