Outcome

Type Measure Description Time frame Safety issue
Primary Level of presence od viral or bacterial infection, level of expression of SHH and VEGF in varicose vein wall. . Qualitative and quantitive analysis (presence and concentration - µl or U/µl in two different laboratory tests.) to detect genetic material (DNA, mRNA) of bacteria/viruses will be performed. The outcomes from both gropus will be compared. one year after finishing recruitment
