Biochemical analysis of dermal connective tissue in subjects affected by primary uncomplicated varicose veins.
Biochemical analysis of dermal connective tissue was carried out in 14 subjects affected by primary uncomplicated varicose veins and 14 controls. Skin samples were taken, according to fixed criteria, from operation pieces of total mastectomy for breast cancer. The results suggest that the dermal tissue in these subjects is just thinner than that of controls, confirming previous similar clinical findings. The elective reduction of the collagen content observed, unassociated with changes of other components of the dermal connective tissue, brings evidence for a systemic biochemical defect of the extracellular matrix i.e. a collagen defect affecting the entire body structure and not only the varicose or pre-varicose veins of the lower limbs.
