Treatment of May-Turner syndrome as a cause of chronic pelvic pain, with an assessment of the clinical effect after stenting of the left common iliac vein

Introduction. Chronic pelvic pain (CPP) is chronic or persistent pain perceived in structures related to the pelvis of men and women.CPP is often associated with compression of the left common iliac vein (CIV) by the right common iliac artery, i.e. May-Turner syndrome (MTS). MTS treatment consists in surgical elimination of vein compression by the endovascular method - stenting of the left CIV.Purpose of the study. Evaluation of the clinical effect after stenting of the left OPV in STSMaterials and methods. We performed 27 stentings of the left iliac veins for MTS. 27 (100 %) complained of chronic pain in the pelvic area of varying degrees of intensity (4-8 points on the VAS scale). Assessment of the clinical status of the operated patients, as well as ultrasound of the veins of the lower extremities and small pelvis, was performed on the 30th day after discharge from the hospital and 6 months later at the control visit.Research results and discussion. The technical success of stenting was achieved in 100 % of patients. All stents were patent by ultrasound. No adverse events were observed in this group of patients during the 30-day period.The subjective assessment of the degree of regression of primary complaints, according to the questionnaire, was 48.3 %. Patients noted an improvement in the quality of life, a persistent reduction in pain.Further analysis showed that within 90-180 days after surgery, the degree of regression of primary complaints approaches 86.3%.Conclusion. Stenting of the left CIV, elimination of compression and improvement of venous outflow from the pelvic organs, within 90-180 days after surgical treatment, leads to the desired clinical effect with the relief of chronic pelvic pain or a persistent decrease in the degree of pain syndrome (the degree of regression of primary complaints is 86.3 %).
