Pelvic venous disorder (PVD) in women is a polyetiological multifactorial disease characterized by a high prevalence (up to 80%), a high risk of infertility, and a progressive recurrent course. Morphological changes of the venous bed occur in PVD, contributing to retrograde blood flow and pelvic phlebohypertension. It is occur due to dynamic hypervolemia and hypertension long-term exposure on the venous wall. However, PVD pathogenesis analysis only from venous hemodynamic disorders position does not explain all mechanisms of the disease development and does not contribute to the treatment measures effectiveness. Currently oxidative stress reactions are considered as the most important markers of the pathological process. The aim of our work was a comparative analysis of lipid peroxidation-antioxidant defense component changes in the peripheral and regional blood flow in women with primary pelvic venous disorder depending on the disease stage. The study involved 137 women of reproductive age (mean age 37.4±9.1 years old) with diagnosed primary PVD divided into 3 groups according to the pathological process stages (stages I, II, III). Data from 30 practically healthy women (mean age 33.5±6.3 years old) were used as controls. Spectrophotometric, fluorometric, immunoassay and statistical methods were used. In patients with PVD stage I in peripheral bloodstream were higher values of SOD and GPO activity; in the regional bloodstream were higher levels of TBARs, SOD, catalase, GPO and lower GSH. In PVD stage II the peripheral bloodstream showed elevated levels of DC, GSH and SOD reduced levels; the regional bloodstream showed higher levels of DC, TBARs, GPO and GSH reduced levels relative to controls. PVD stage III was characterized by: higher levels of DC and TBARs and lower levels of SOD and GSH in the peripheral bloodstream; higher levels of DC, TBARs and lower levels of GSH and catalase in the regional bloodstream compared with control. Thus, the results of our study showed no significant differences in the LPO-AOD system between peripheral and regional bloodstreams in patients with PVD depending on the disease stage. However, negative changes in the redox balance in the regional bloodstream were earlier and were already registered at the first stage of the disease. It is likely that control of antioxidant insufficiency in patients with PVD should be an important component of preventive measures in the early stages and pathogenetic treatment in the pathological process progression, particularly in stage III of the disease.
