| E.1 Medical condition or disease under investigation | 
| E.1.1 | Medical condition(s) being investigated | 
| We will include patients with insufficiency of the long and/or short saphenous vein as underlying cause of their venous leg ulcer. These patients may or may not have visible varicose veins of the long and/or short saphenous vein.

 Chronic venous hypertension with ulcer ICD-9-CM-459.31
 Chronic ulcer of the skin ICD-9-CM-707

| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial | 
| The aims of the study are to determine: 
 - the effect of foam sclerotherapy on the incompetent venous trunks
 - the effect of foam sclerotherapy in addition to compression therapy on ulcer healing
 
 Set up a prospective, randomized, controlled trial
 |  | 
| E.2.2 | Secondary objectives of the trial | 
| - the feasibility of performing foam sclerotherapy in patients with damaged, ulcerated skin in an outpatients setting - the assessment of the cost of foam sclerotherapy treatment
 - quality of life of the patient before and after their treatment
 
 |  | 
| E.2.3 | Trial contains a sub-study | Information not present in EudraCT | 
| E.3 | Principal inclusion criteria | 
| - strict venous leg ulcer - ulcer > 4 weeks old
 - active ulcer CEAP classification C6
 - full assessment: - venous duplex scanning
 - arterial doppler with ABPI > 0.85

 |  | 
| E.5 End points | 
| E.5.1 | Primary end point(s) | 
| Primary endpoint will be the mean time to healing of the leg ulcer 
 Secondary endpoint includes the proportion of the ulcers healed at 12 and 24 weeks

| E.8.8 | Definition of the end of the trial and justification where it is not the last

| Patients will be seen for the last time in trial 6 months after they started their therapy (group A compression therapy alone) (group B compression therapy and foam sclerotherapy). If the ulcer hasn't healed at 6 months they will be followed up for another 6 months. If at that stage the ulcer still hasn't healed they will be classified as "non-healers" in the study. After 1 year ne data will be collected anymore. |  |
