  • Vein size <20 mm in upright position 60 degrees, 2 cm below the SFJ.
  • Minimum distance between skin and the GSV in the first 20 cm from the SFJ > 5mm.
  • CEAP classification C2-C5
  • BMI <35

Who cannot join

  • Non-consent for randomisation.

  • Deep vein insufficiency in the same extremity (duplex verified).
  • Vein size >20mm in upright position 60 degrees below the SFJ.

Show all 15Show fewer
  • Patients with double GSV's and/or lateral accessory insufficient branch.
  • Patients with cognitive disturbances, dementia or unable to understand for any reason the importance of follow up.
  • Earlier operation with HL/S (recurrency).
  • Operated for small saphenous vein (SSV) incompetence the last 3 months.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • High Ligation of the GSVProcedure or surgery

    Performed in local or general anesthesia in accordance to clinical praxis and the patients own preference. After high ligation the GSV is stripped from the groin to the most distant insufficient part or just under the knee joint.All proximal branches are ligated. Including the superficial epigastric vein. The stripping instrument can be inserted in either cranial or caudal direction but all veins are stripped in the cranio-caudal direction.

  • Endovenous Laser AblationProcedure or surgery

    Laser ablation is performed in tumescence anesthesia which is performed with a 150-200 ml (sometimes more is required, up to 400ml in patients with a poorly formed saphenous sheath) solution of lidocaine with adrenaline supplement. General sedation can be administrated as a supplement (with intravenous Propofol or Dormicum when needed). Laser is performed under duplex guidance and the catheter is inserted percutaneously into the GSV at knee level and parked distant to the saphenofemoral junction (SFJ) just distal to the superficial epigastric vein. Laser ablation is performed down to the most distal insufficient part of GSV or just below the knee joint. We use an effect of 14 Watt administration of 70-80 J / cm at a continuous mode at a speed of 1cm/5sec.

  • Radiofrequency ablationProcedure or surgery

    RF ablation is performed in tumescence anesthesia which is performed with a 150-200 ml solution (same as above) of lidocaine with adrenaline supplement. General sedation can be administrated as a supplement (with intravenous Propofol or Dormicum when needed). RF is performed under duplex guidance and the Closure-FAST catheter is inserted percutaneously into the GSV at the knee level and parked distant to the SFJ just distal to the superficial epigastric vein. Probe size and length used for RF is chosen in accordance to the manufacturer's recommendation and with a probe temperature of 120 degrees C. RF closure is performed down to the most distal insufficient part of GSV or just under the knee joint.

  • Foam SclerotherapyProcedure or surgery

    Sclerosant foam consists of 2ml 3% aethoxysclerol mixed with 8ml air (Tessari method). A maximum of 10 ml is injected. Access to the vein for the sclerosant is gained by a duplex guided puncture or a mini incision mid-thigh or just above the knee and the amount of sclerosant foam used is 2,5-10 ml. Duplex is used prior to the operation in order to mark the vein and during the operation in order to control the extent of the sclerofoam. Duplex validates that foam is deposed to the whole length of the GSV. Blood from the veins is drained by means of elevation prior to the deposition of the sclerofoam. The leg is then bandaged with elastic bandage.

Questions about this trial

What is this clinical trial studying?

A study testing High Ligation of the GSV, Endovenous Laser Ablation and Radiofrequency ablation in people with Varicose Veins, run by Uppsala University at 1 site in Sweden.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Feb 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Sweden. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Recurrence rate and complications after venous surgery. Duplex ultrasound and clinical evaluation. (time frame: 3 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Feb 2014.
