Treating the Branch Veins

Ultrasound-guided sclerotherapy — reaching vessels below the visible surface

What Remains After the Source Vein Is Closed

Even after the source vein is closed, reticular veins branching from it often remain. Though smaller than the saphenous vein, if left untreated they contribute to leg heaviness and to the veins visible through the skin.

The Vessels Causing Symptoms Are Often Not the Large Ones

Some patients still have symptoms after surgery — because the vessels causing them are often not the named trunks, but small veins adjacent to sensory nerves.

Ultrasound-Guided Sclerotherapy

This stage uses ultrasound-guided sclerotherapy — injecting a sclerosing agent with ultrasound guidance so that veins below the visible surface can be treated precisely.

Precision ultrasound visualizes reflux even in needle-sized vessels, and the sclerosant is injected into those veins, which gradually fade.

Post-Procedure Pigmentation Care

Temporary hyperpigmentation can follow sclerotherapy. da Re-Fit Clinic runs a dedicated post-procedure pigmentation care protocol alongside treatment.

Adjunctive tranexamic acid and glutathione for the prevention of post-sclerotherapy hyperpigmentation and phlebitis was among the topics presented at the Asian Venous Forum 2026 in Fukushima, Japan.

Treated Gradually, With Follow-Up

This stage is more demanding and more delicate than Stage 1, and is carried out while observing progress over time. Scope and number of sessions depend on vessel condition and are discussed after ultrasound examination.
