VenaSeal – glue over 5 Years: A follow-up study conducted on 1540 truncal saphenous veins in 865 cases



VenaSeal – glue:  We report about our 5 years – results of a retrospective comparative study of VenaSeal – glue in the treatment of 1540 saphenous veins  (1085 GSV, 428 SSV, 27 VSAA ) in 865 cases. Treatment included also ulcera crures in 8 cases.


Since 17 years by now, varicosis has been increasingly treated endovenously. At the start, the rather inconvenient VNUS®Closure plus procedure and the more convenient linear laser procedure were used, and these were followed in 2006 / 2007 by the bipolar RFITT® – catheter, the VNUS®ClosureFast – system and the radial laser. Thus, in the course of the last 15 years, plenty of experience has been gathered with endoluminal therapy, quality criteria have been defined and standards for the different techniques have been developed. The author has applied Venaseal for the first time in a great saphenous vein on 1st. August 2012.

Material and Method

During the time period from 1st. August 2012 to 31st July  2017 (60 month), Venaseal – glue  was applied to achieve closure of the vein in 1540 saphenous veins. In 271 patients one saphenous vein were treated; in 518 patients two saphenous veins were treated; in 65 patients 3 saphenous veins were treated and in 8 cases all the four saphenous veins were treated simultaneously.

In VSAA veins we treatet the inguinal trunc in length between 12-25 cm.

The follow-up observation period in our study was up to 60 months.

In 1085 cases the greater saphenous vein was treated, in 428 cases the small saphenous vein was treated an in 27 cases the trunks  of VSAA  were sealed.

VenaSeal – glue interventions were performed under light sedation with Dormicum or under local anesthesia for venous access accompanied by music therapy, 42 patients did`nt got any anaesthesia (2,8%).

All patients are given a follow-up examination by duplex sonography in the scope of a prospective study (our own quality management) on the 1st / 14 – 30th  day,  70 – 90th.  day as well as after 6 and 12 months. After this we controlled every following year. All duplex sonography examinations post intervention were done by an other collegue, not by the vascular surgeon treated the truncal veins.


On the 1st. day 1540 saphenous veins were checked (1528 were closed initially = 99,2 %) in the scope of follow-up.  Up to the 30th. day, partial recanalization was found in 31 veins, and complete recanalization was found in 7 veins. This corresponds to a closure rate of 97,5 %.

Over a time period of 3 months up to 6 month, we were able to follow up 1370 saphenous veins ( 89 % ) of all veins that had been treated), and here we found 30 partial and 10 complete recanalizations. The closure rate is 97,4 %.

1198 saphenous veins ( 77,8 % ) were followed up over a 6-month time period, and 32  partial and 12 complete recanalizations were found – resulting in an effectiveness of 97.1 %.

No further recanalizations were found after a 38 – month follow – up period in 1111 saphenous veins ( 72,2% ) up to now. All leg ulceras were healed until to 14 days after intervention.

1540 veins having been glued with VenaSeal – glue, the results achieved over the entire time period of 60 months are equivalent to a closure rate of 97.1 %. – This is nearly the same result like published in the „Veclose – study“  – 

Here the colleagues present a closure rate of 96,8 % in sealing GSV. Congrats!

All our patients were able to leave the office between 30 and 90 minutes after the intervention.

In the case of VenaSeal, we have up to now refrained from applying compression therapy in 98% of all cases. We prefer to use compression stockings only in cases, the diameter of the treated vein ist over 1,5cm or in treatment of venous aneurysm or ectatic varicose veins.

Side effects

We found side effects in 8 % of all cases. An unspecific inflammatory reaction of tissue we have seen in 7 % of all cases. A long term ecchymosis we saw in 1 % of treated patients, especially in extra anatomic subcutaneous truncal veins. Bleeding ex punctio   > 12h we found in 14 cases we continued intra operativ with anticoagulation.

Lymph fistulas at the puncture side we saw in 3 cases, In one patient we had to therapy a glue pimple with cutaneous perforation after 11 month post sealing.

There was not to be found:  hyp – / paresthesia, permanent skin reaction, no phlebitis or thrombosis and no allergenic reaction!

VenaSeal – glue:  Discussion

Now we have guidelines in Europe using endovenous systems at first (ESVS 2015) in treatment of truncal saphenous veins. Thus, the colleagues who work with endovenous procedures meanwhile have reliable criteria for a high-quality therapy.

All these endovenous methods also have clinical advantages and quite significantly reduce side effects and complications such as still occur regularly today as in the past in connection with the conventional surgical technique.

In Venaseal – glue we do not need anesthesias anymore and can in most cases do without postoperative compression therapy. Elastic stockings should nevertheless by all means be recommended after the treatment of thicker saphenous varicose veins measuring > 1,2 cm, and they become compulsory where we intend to apply gluing therapy in larger lumens measuring 1.5 cm and more.

The significantly reduced side effects and a well-nigh negligible pain score are also clear advantages in comparison to laser and radio wave therapy. No paresthesias, no hypesthesias, no phlebitis,  rare occurrence of skin pigmentations are only a few of the important advantages of the VenaSeal – glue procedure.

The results of first long time comparative studies show that the VenaSeal – glue is clearly superior with regard to postoperative side effects though. Both the pain score and the rate of side effects are very low in comparison. Particularly pain as well as the neurological side effects no longer play any significant role at all. These are the main problem associated with laser and radio wave therapy though.

In practical work with VenaSeal – glue, all insufficient saphenous veins should as far as possible always be treated in one session. In practical also perforators and junctions of side branches should be treated. And also ectatic or aneurysmatic parts of truncal  veins we can treat with glue.

VenaSeal – glue: Conclusions

Venaseal – glue is one of the endovenous techniques with a hight standard of effectiveness – quality standards are the same like other endovenous procedures.

VenaSeal – glue  is safe in treatment of all truncal veins, side branches and peforator veins until a diameter of 2,0 cm, higher diameter is possible but the radio frequency is safer.

VenaSeal – glue is the most expensive of all endovenous techniques.

Independently of this, we at SAPHENION meanwhile regard Venaseal – glue as treatment of first choice in the range of catheter – supported therapeutic procedures for all truncal varicose veins, f.e. GSV and SSV or inguinal VSAA. – but specially in lower legs truncal veins and in GSV – stadium 3-4 VenaSeal is the favorite.

  1. I‘ m a Spanish vascular doctor. I treated oclusión 4 legs with Venaseal Technique.
    One patient have a erythema on the surface of 2 saphenous Vein treated 10 days after the procedure. It‘ is frequent?
    Can I expect spontaneous and rapid improvement?
    There are for you the veins diameter limits for this therapy ?
    Thank you very much for share your great experience!!

    • nearly 10% of all treated legs show the erythema, take cool alcoholic compression for 2-3 day and the problem is over, we are treating also veins until to 2 cm diameter.

  2. Have you experienced any allergy reactions to the CA glue? I have performed Venaseal in over 50 patients with phlebitis being the only complication of note. However the prospect of dealing with CA glue allergy still concerns me? What are your thoughts on this?

    • Hello Paul, No I haven`t experienced any allergic reaction – and Your phlebitis isn`t this – it`s a perivascular tissue reaction, we see this in 8% of all patients, especially in extra anatomic subcutaneous truncal veins – the vein wall is damaged and the lymph fluid is coming in contact with the glue – so it is an unspecific reaction you can see this in ultrasound control. cool down the tissue with cold alcoholics – not much more is nessesary greetings!

  3. Thank you for your help. I like the idea of a cold compress but I’m unsure what you mean by „cold alcoholics“ ? Do you mean ethyl chloride spray? Kind regards Paul.

  4. Hi

    I have been treating truncal insufficiency with different ENDOVENOUS techniques including laser and Raidio frequency ablation for the past 10 years, recently I have treated a patient with Venaseal, Full length of the Great saphenous vein was treated, unfortunately the patient developed extensive thrombophlebitis 2nd day of post op. with increase CRP to 330. Patient required hospitalisation and treated with antibiotics and steroids. The care is still on going. I did not experience anything like that with any other techniques for treatment of Venous insufficiency. The pain has been quiet excessive as well. Does anyone had similar experience? Sever allergic reaction?

    • Hi Iraj, thanks for Your comment – we never have seen this clinical picture, also not in cases with immun suppressive therapy , but it is possible a case of lupus? – the therapy with antibiotics show – maybe – an infection? allergenic reactions are not the case…unspecific inflammatory reaction 5 to 10 days after treatment are possible – we only make cool alcoholic bandage, in one case we gave cortisone for 3 days…
