Optimal application area
Non-saphen veins are not connected to the great and small saphenous veins, so their expansion is often local in nature and responds well to sclerotherapy without surgical intervention. In the first degree, a small area with veins of moderate caliber is affected - usually one or two sessions are enough. The drug is administered under ultrasound guidance, which allows you to accurately enter the lumen and monitor the spread of the sclerosant.
How does sclerotherapy work?
The sclerosant causes controlled damage to the inner lining of the vein. The vessel collapses, sticks together and within a few weeks turns into a thin cord that dissolves and becomes invisible.
The method does not require incisions or anesthesia, is performed on an outpatient basis and allows you to return to normal life immediately. However, it is not universal: large trunks with pronounced reverse blood flow are not treated with sclerotherapy - laser obliteration is needed there.
An important condition for success
Spider veins and small veins are often just the tip of the problem. If there is an incompetent feeding trunk underneath them, sclerosis of the superficial veins will give a temporary result: in a few months they will appear again. Therefore, duplex scanning before treatment is mandatory, and when reflux is detected, its cause is first eliminated.
What to expect after the procedure
- veins darken and become more noticeable in the first 2-3 weeks - this is normal
- slight bruising and compaction along the vein are possible
- the final result is assessed after 4–8 weeks
- Full effect usually requires 2–4 sessions
