What is the difference between varicose veins and venous dilatation?（The next passage）

For example, liver cirrhosis and portal hypertension may cause superficial abdominal wall varicose veins, commonly known as sea snake head.

If the vein dilation is caused by a clear pathological factor, it will usually recover when the original disease is treated and the pathological factor is removed.

The cause of varicose veins is usually clear, such as venous valve dysfunction, venous thrombosis, venous stenosis and blockage, or certain congenital diseases, which may cause pathological varicose veins.

To determine whether varicose veins or venous dilatation can be determined, it requires a doctor's outpatient consultation, detailed physical examination, and ultrasound hemodynamic evaluation.

In addition, esophageal and gastric varices, hemorrhoids, etc. are all varicose veins, which usually require active treatment, otherwise they are prone to complications.

Of course, there are also a small number of people who have obvious venous dilation, feel uncomfortable or feel that it affects their appearance, and want to improve it.

There have been reports in foreign literature that the vein dilation on the back of the hand uses intracavitary thermal ablation to improve the appearance.
