Objective: to study the effectiveness of methods of endovascular treatment of May-Turner syndrome and nutcracker syndrome as a cause of varicose veins of the pelvis in men with chronic pelvic pain syndrome.
Materials and methods: a comprehensive examination was carried out in 445 men with chronic pelvic pain syndrome. The patients’ age ranged from 20 to 68 years (mean age 39.5 years). The diagnosis of varicose veins of the pelvis was established in 49 patients, of which 25 had primary varicose veins of the pelvis, in 24 – secondary varicose veins of the pelvis (13 patients with May–Turner syndrome, 11 patients with nutcracker syndrome).
The patients with the nutcracker syndrome underwent embolization of the testicular and pelvic veins using the combined sandwich technique. Patients with May–Turner syndrome underwent stenting of the left common iliac vein.
Results: In order to assess the technical efficiency of endovascular treatment, control ultrasound was performed at 1, 3, 6 and 12 months. In 100% of cases, throughout the observation period, the patency of venous stents was maintained; in all cases of embolization of the left testicular vein, there was no blood flow in the embolized vein. In order to assess the clinical efficacy of endovascular treatment after 1, 3, 6, 9 and 12 months. after it, patients were questioned using the NIH-CPSI scale and VAS. The most significant changes in clinical manifestations and ultrasound data were observed after 3 months. after endovascular treatment.
Conclusions: Balloon angioplasty and iliac vein stenting in May-Turner syndrome and left gonadal vein embolization in nutcracker syndrome are minimally invasive treatments with a favorable patient safety profile.
