FAQ Varicose veins

Here are some frequently asked questions about varicose veins:

Why do spider veins and varicose veins develop?

Venous disorders always develop based on inherited venous weakness, rarely directly after venous thrombosis.
External triggering factors are usually: lack of exercise, being overweight, standing or sitting for long periods, and smoking.

How to treat these venous disorders?

Spider veins and varicose veins can be removed in two ways. Either they are “sclerosed” by injecting certain drugs through a syringe and various injection techniques or by laser treatment.

What should be considered before the treatment?

Before any vein treatment, an apparition, painless examination of the flow conditions and the condition of the venous valves is necessary.

Do varicose veins tend to recur repeatedly?

Tissue ages, and the venous valves become fewer and fewer with age and lose their function. This means that the appearance of varicose veins cannot be ruled out after treatment.

Do varicose veins get stronger after surgery?

After a carefully executed operation on the affected veins and thorough elimination of all causes, there is no reason for it to persist.

How long do I have to wear compression stockings after surgery?

VenaSeal treatment: None
Radiofrequency treatment: about one week

How long is the recovery period after a vein operation before returning to work?

This depends entirely on the method used. As a rule, you will be on sick leave for 2-3 weeks.

How long after a vein surgery should one refrain from doing sports?

The stripping patients can usually only exercise after 4-6 weeks.

Can brown or white spots appear after laser treatment of spider veins?

That is not entirely ruled out. The very gentle and currently most modern laser system we use probably produces the fewest brown or white spots, but it is still conceivable in individual cases.

Where does the blood flow after the veins are removed?

The veins removed or disabled during treatment are unfortunately defective and therefore did not contribute to venous return before treatment. Their removal does not worsen venous circulation; on the contrary, it redirects blood flow to other normal healthy vessels.
This improves the venous backflow and broods down.

Are there any side effects?

Light physical activity is possible. In rare cases, mild pain may occur in the treated area, but it typically subsides within a few days. In very rare cases, superficial inflammation of the treated areas may occur. This subsides quickly with cooling, rest, and heparin dressings. Similarly rare, a dark discoloration of the skin in the treated area may remain along the formerly affected veins.

Are varicose veins dangerous?

In these pathologically enlarged veins, blood accumulates in the periphery, leading to a buildup of toxins, acids, and oxygen deprivation due to a lack of proper circulation and exchange of used blood with fresh blood. This can lead to malnourishment of the skin and subcutaneous tissue, resulting in an open wound on the lower leg known as an “ulcer,” “crural ulcer,” or “leg ulcer.” Furthermore, blood clots, known as “thrombi,” can form.

If such a clot blocks a vessel, it is called thrombosis.

If it is torn loose and then reaches the lungs through the bloodstream (via its natural pathway), it can cause the blockage of pulmonary blood vessels, a process known as pulmonary embolism, which is a severe complication.

Moreover, superficial veins blocked by a thrombus can become inflamed and infected, leading to pus-forming bacteria entering the bloodstream and triggering severe medical conditions such as sepsis.

FAQ VenaSeal

Here are some frequently asked questions about VenaSeal:

How is VenaSeal performed?

During a VenaSeal procedure, the doctor makes a small incision in the skin near the affected vein. Then, a special adhesive called Cyanoacrylate is injected into the vein through a catheter. The adhesive closes the vein, preventing blood from flowing through it.

Is VenaSeal painful?

VenaSeal is usually a minimally invasive procedure performed under local anesthesia. This means the area around the affected vein is numb, so the procedure should not be painful. Some patients may feel slight discomfort or pressure during the procedure, but this should be tolerable.

How long does the VenaSeal procedure take?

The VenaSeal procedure usually takes 30 to 60 minutes.

What is the recovery time after VenaSeal?

Recovery time after VenaSeal is generally shorter than other procedures used to treat varicose veins, such as stripping or laser treatments. Most people can resume their normal activities after one day.

What is the success rate of VenaSeal for the treatment of varicose veins?

The success rate of VenaSeal for treating varicose veins is usually outstanding. A randomized prospective study from the USA (VeClose-published 2018 by K. Gibson) reported that 96% of patients treated with VenaSeal did not experience regression of varicose veins within two years of treatment.

Do you have an increased risk of circulatory disturbance of the leg vessels, stroke, or heart attack?


Do you suspect varicose veins, or have they already been diagnosed?

With the help of thorough vascular diagnostics, problems can be identified early, and severe secondary diseases can be averted.
