Study Arms (2)

Group A, MOCA-group

Procedure/Surgery: MOCA Mechano-Chemical Ablation plus Elastic Compression

Device: Endovenous Mechano- Chemical Ablation

Group B, Elastic Compression only group

Treatment: Elastic Compression only

Interventions

The Flebogrif™ catheter (Balton® Sp. z o.o., Warsaw, Poland) represents endoluminal Non Thermal Non Tumescent devices designed to cause occlusion (fibrosis) of the target vein through the combined mechanical and chemical damage to its endothelial lining with retractable cutters and foamed sclerosant.

Also known as: MOCA
Group A, MOCA-group

Sampling MethodProbability Sample
Study Population

Patients with GSV incompetence and C6 were included in in the prospective consecutive case study if they satisfied the selection criteria.

You may qualify if:

  • Patient age \> 18 years.
  • Current leg ulceration of greater than 6 weeks.
  • Great saphenous vein (GSV) incompetence with reflux at least down to the knee level.
  • Primary symptomatic varicose veins, Clinical Etiological Anatomical Pathophysiological (CEAP) classification, clinical class C6.
  • Able to give informed consent to participate in the study after reading the patient information documentation.
  • Ankle Brachial Pressure Index (ABPI) ≥ 0.8.

You may not qualify if:

  • Postoperative varicose veins disease recurrence.
  • Patients who are unable to tolerate any multilayer compression bandaging / stockings will be excluded.
  • Deep venous thrombosis, thrombophilia associated with a high risk of deep venous thrombosis or postthrombotic syndrome.
  • History of pulmonary embolism or stroke.
  • Current anticoagulation therapy (within 7 days of enrollment).
  • Pregnant or lactating women.
