Outcome Measures

Primary Outcomes (1)

  • Quantification of the blood flow before, during and after the medical therapy

    The primary objective of this study is defined by the dynamics of the (post)capillary blood flow before (baseline value) and 12 weeks after treatment, measured by means of the LRR. In doing so, the therapeutic effect, in terms of the change in (post)capillary blood flow after treatment compared to baseline value, is to be quantitatively determined.

    24 weeks

Secondary Outcomes (1)

  • Emerge of new ulcers

    > 24 weeks

Study Arms (2)

Prostavasin
