What is a vein adhesive (VenaSeal) in general?

Acrylic-based vein glue is used to glue varicose veins without surgery or anesthesia to close the vein and redirect blood to alternative veins.

It is non-toxic, non-carcinogenic, and does not cause allergies. Important: For spider veins, we use a different therapy. Here, vein glue cannot be used.

What is the vein glue (VenaSeal) in particular?

VenaSeal (vein glue) or the VenaSeal (vein glue) Closure System is a new type of vein glue made of acrylate that closes the diseased truncal vein to heal it permanently. The cyanoacrylate we use is an entirely biodegradable adhesive that is also very tissue-compatible and, of course, non-carcinogenic. Surgery or anesthesia is unnecessary, the treatment takes about 20 minutes per diseased vein, and almost all patients are ready to return to work immediately.

What are the first signs/symptoms of venous insufficiency?

Varicose veins are enlarged veins resulting from a vein defect, usually due to abnormal blood flow through a deformed venous valve and a thin vein wall. This is due to a weakness in the connective tissue, which means the venous valves no longer function properly.

The first signs of weak veins and the appearance of varicose veins are changes in the skin color on your leg or when your legs feel heavy after moving for a long time. But also pain in the legs after long walking or standing, tired and swollen legs, or cramps in the calf or foot are signs that you should quickly talk to a doctor. If left untreated, varicose veins can worsen and lead to open ulcers on the leg or, in rare cases, even to life-threatening pulmonary embolisms.

More about varicose veins

How does the individual treatment with the vein glue (VenaSeal Closure System) work?

Since varicose veins often run in families, the inheritance of venous insufficiency plays a role in the development of varicose veins. However, current complaints, medical history, and a physical examination also provide decisive indications of varicose veins. Various diagnostic methods such as B-mode ultrasound, venous Doppler ultrasound, and digital photoplethysmography (D-PPG/LRR) provide information about more profound changes.

Knowing the causes of your vein disease is the first and most crucial step to effective healing. Once we have worked with you to identify these causes, the specialist appropriate to your diagnosis and their team will attend to you and answer your questions, assess your venous disease, and provide you with a unique and comprehensive treatment plan based on your needs. If an individual treatment with VenaSeal (vein glue) is recommended, you will be informed in detail by our specialists, and the complete treatment plan (usually consisting of several treatment approaches) will be outlined for you. Treatment with VenaSeal bioadhesive (vein glue) is performed as follows:

The treatment is outpatient, and no general anesthesia is necessary. By means of a small puncture and a catheter, a medical vein glue is gradually inserted into the varicose vein with light pressure. The treatment does not require local anesthesia and is continuously monitored by ultrasound to ensure the safe closure of the vessel.


The advantages of individual treatment with the vein adhesive (VenaSeal Closure System) are obvious:

  • Only a small puncture and an appropriate catheter are needed to gradually introduce the VenaSeal bioadhesive (vein glue) into the varicose vein with light pressure, where it permanently ensures the healing of the truncal vein while redirecting blood to other veins. The truncal vein (the root of a varicose vein) is healed in a few weeks, and after about 12 months, the adhesive is broken down by the body without complications.
  • An outpatient, minimally invasive, and non-painful procedure of about 20 minutes per truncal vein leads to complete healing of the varicose vein.
  • No general or local anesthesia
  • No skin burns or nerve damage as may occur with other therapies
  • VenaSeal bioadhesive (vein glue) is completely biodegradable, non-carcinogenic, and does not cause allergic reactions
  • A rapid recovery phase for the patient is guaranteed
  • Medication and compression stockings are not necessary after treatment
  • A sick note is not required

What must I pay attention to after VenaSeal bioadhesive (vein glue) treatment?

Since the therapy with bioadhesive VenaSeal (vein glue) is performed in a very uncomplicated and tissue-friendly way, no special aftercare is necessary. There is also no need for medication or compression stockings.

Are there any side effects of treatment with VenaSeal bioadhesive (vein glue)?

A mild side effect could be a short-term inflammatory reaction caused by the initial contact of the lymph with VenaSeal bioadhesive (vein glue). However, it is easy to remedy the situation with cooling bandages. In addition, there is a short-term increase in inflammatory parameters in laboratory chemical control.
