If you're referring to the second stage of varicose veins, I'm not sure if you mean the clinical manifestation stage two, or if it's a recurrence after one surgery.

Let's first talk about stage two varicose veins, which means there are visible and tortuous vein clumps. There are several main treatment methods for this condition:

First, conservative treatment, which involves wearing medical compression stockings. If symptoms include soreness, heaviness, or cramping, some medications can be taken orally. Then, if there is a desire for surgical treatment, options like vein stripping, radiofrequency, or laser treatments are available. Some may involve sclerotherapy or another method called venous angle keratin treatment, specifically for stage two varicose veins.

If it's a recurrence of varicose veins, we need to assess the specific situation. Some people might have had previous endovenous closure surgeries, and their veins are still present. In such cases, we can choose to redo the closure or opt for surgery to remove them.

Another scenario is if the varicose veins have recurred after surgery. We need to investigate the cause. Some people might have iliac vein stenosis, and in such cases, treatment targeted at the iliac vein is necessary.
