Varicose veins in the lower limbs are a common and frequently occurring disease among peripheral vascular diseases. Due to factors such as blood stasis and thinning of the venous wall, the venous pressure increases, leading to the tortuosity and dilation of veins. Varicose veins can occur in veins of various parts of the body, such as hemorrhoids, which are actually a type of varicose veins in the lower limbs. Clinically, there are also varicose veins in the lower limbs and abdominal wall, etc. The most common occurrence of varicose veins is in the lower limbs. It is worth emphasizing that varicose veins in the lower limbs themselves may be a secondary manifestation of other diseases, such as caval vein occlusion, and should be actively treated for the primary disease.
In the early stage of the disease, there may be no discomfort. As the disease progresses, there may be symptoms such as aching and fatigue in the affected limb after prolonged standing or walking, as well as cramps in the calf muscles. When standing, the affected limb may show prominent, tortuous, and dilated veins. In severe cases, they may appear in a mass-like state. Long-standing patients may develop chronic ulcers, hyperpigmentation, hardening of the skin, and varicose veins with thrombophlebitis in the area of the lower leg (the front and lower part of the lower leg).
