Varicose veins of the abdominal wall have a different pathogenesis than varicose veins of the lower extremities. The varicose veins of the lower extremities are mostly primary, with problems in their own veins, resulting in varicose veins of the lower extremities, while the varicose veins of the abdominal wall are mostly secondary to compensatory manifestations. The main cause is due to portal hypertension and vena cava obstruction. When portal hypertension and vena cava obstruction occur, the blood flow is restricted and the restricted blood flow causes an increase in local pressure, resulting in compensatory dilation of the abdominal wall veins, which manifests as abdominal wall varicose veins. When abdominal wall varicose veins appear, it is recommended to promptly visit the vascular surgery clinic for detailed examination, clear diagnosis, and professional and meticulous treatment under the guidance of a specialist. In the case of abdominal wall varicose veins, they are often combined with other diseases and require more attention during the examination.
