Objective — the aim of the present study was to elucidate the relationship between the degree of expansion of intrapelvic veins and the severity of symptoms of pelvic venous congestion (PVG) in the patients presenting with pelvic varicose veins (PVV). Material and methods. The study included 42 patients with TSWV at the age from 32 to 48 years, averaging 39.4±1.53 years. Twenty two women among these patients had the disease accompanied by pelvic venous congestion (PVC) and were allocated to group 1. Group 2 was comprised of 20 patients exhibiting no signs of PVC. Vulvar varicose veins (VV) were detected in 3 patients of group 1 and in 11 ones of group 2. All the patients were examined by ultrasound angioscanning (US) and emission computed tomography (ECT) of the pelvic veins. Results and discussion. The study has demonstrated that the most important factor responsible for the development of PVC and pelvic pain is the prevalence of the involvement of intrapelvic veins in the pathological process rather than the degree of expansion of varicose veins. In addition, significant differences were observed between the number of patients with vulvar varicosities in the two treatment groups. Group 1 contained 13.6% of such patients compared with 55% in group 2 where more patients had a larger diameter of vulvar veins. The correlation analysis of the relationship between the diameter of pelvic veins and the severity of CPP in group 1 showed a very weak interdependence (r=0.1) between these parameters. In the second group, such relationship was totally absent. The correlation coefficient for the whole group included in the study was 0.01 which also indicates a very weak relationship between the diameters of the pelvic veins and chronic pelvic pain. Conclusion. The results of the present study give evidence that the clinical picture of PVV and the presence of PVC symptoms do not depend on the degree of expansion of the pelvic veins.
