Use of microcirculatory parameters to evaluate clinical treatments of chronic venous disorder (CVD).

Objectives: To evaluate changes on cutaneous microangiopathy in chronic venous disorder (CVD) after use of Cirkan [venotonic drug containing Ruscus aculeatus (plant extract), hesperidine methylchalcone (flavonoid) and vitamin C], elastic compression stockings (ECS) or no treatment for four weeks.

Patients And Methods: Fifty-five female patients (85 legs), 25 to 57 years, with at least one limb classified as C2,s or C2,3,s (CEAP classification), were allocated consecutively, according to entrance order, in these three groups. Ten healthy women age-matched were also investigated.

Use of microcirculatory parameters to evaluate chronic venous insufficiency.

Background: Microcirculatory impairment caused by chronic venous hypertension is usually not taken into account in chronic venous insufficiency, probably due to lack of practical means to observe it. The objective of this work was to use a new noninvasive technique to access quantitatively the cutaneous microangiopathy in female patients classified according to CEAP from C1 to C5 and matched with healthy controls.

Methods: Forty-four patients and 13 healthy subjects (112 lower limbs), with a mean age +/- SD of 48 +/- 8 years, were evaluated by using orthogonal polarization spectral (OPS) imaging.
