Varicose veins refer to the tortuous and dilated veins caused by blood stasis, weak vein wall and other factors. Varicose veins can occur in many parts of the body. For example, hemorrhoids are actually a kind of varicose veins. Clinically, there are esophageal and gastric varices, varicocele and abdominal varices.

Varicose veins most often occur in the lower limbs. It is worth emphasizing that varicose veins themselves may be secondary manifestations of other diseases, such as vena cava obstruction, and the primary disease should be actively dealt with.
