Varicose veins of the lower limbs are not a major surgery, they are a moderate surgery. Varicose veins of the lower limbs are very common in clinical practice, they are earthworm-like projections often tortuous in the lower limbs, and if the condition develops further there is a possibility of hyperpigmentation of the lower limbs, or even symptoms of skin breakdown of the lower limbs. Varicose vein surgery is not a major surgery, many hospitals use minimally invasive treatment methods, i.e., radiofrequency ablation, laser, microwave, and combined with foam sclerotherapy for local injection, generally speaking, you can go home after the surgery, without hospitalization, and supplemented with compression stockings after the operation to assist in the treatment. Other parts of the varicose veins from the size of the surgery is not consistent. Such as esophagogastric fundus varices, if the gastroscopic conditions under the ligation and other treatments, are minimally invasive surgery, that is, small and medium-sized surgery, if it is open to the shunt, cut off the flow of surgery and liver transplantation and other operations, it is a major surgery. Hemorrhoidal vein surgeries are all minor surgeries; whereas varicocele surgeries are moderate surgeries. Note that no matter which type of varicose veins you have, you should seek medical attention in a timely manner.
