Research has also shown the importance of pelvic vein reflux (PVR) in the development of varicose veins. Varicose veins in the legs could be due to ovarian vein reflux. [19] [20] Both ovarian and internal iliac vein reflux causes leg varicose veins. This condition affects 14% of women with varicose veins or 20% of women who have had vaginal ...
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]
This incompetence will result in reversed blood flow through the affected vein or veins. It can result in varicose veins and, in severe cases, in venous ulcer. The reversed blood pools in the low third of legs and feet. [17]
The skin surrounding a venous ulcer may be edematous (swollen) and there may be evidence of varicose veins; the skin surrounding an arterial ulcer may be pale, cold, shiny and hairless. Both venous and arterial ulcers may be painful, however arterial ulcers tend to be more painful, especially with elevation of the leg, for example when in bed.
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.
The anterior accessory saphenous vein is a special anterior tributary of the great saphenous vein (GSV), draining the antero-lateral face of the thigh. It becomes very often insufficient, causing important varicose veins with an autonomous course and often is the only insufficient vein present on a patient.
