  • Change in CIVIQ QOL [ Time Frame: 48 Hours ]

    Chronic Venous Insufficiency Questionnaire(CIVIQ) for Quality of Life(QOL). (Min 20- Max 100).

    Global index and an outline of 4 quality-of-life dimensions: "pain" (4 items), "physical" (4 items), "psychological" (9 items), and "social" (3 items). A low global (total) score corresponds to greater patient comfort.
