Syndrome of venous compression neuropathy in patients with pelvic varicose veins

Abstract

The study objective is to investigate the pathogenesis of the development of pelvic symptoms in patients with pelvic varicose veins.Materials and methods. From 2015 to 2022, 145 men with pelvic varicose veins were examined. The examination included questioning of patients using questionnaires (scales) and instrumental methods: 1) ultrasound examination of the scrotum with color Doppler mapping; 2) transrectal ultrasound examination of the prostate and veins of the periprostatic plexus; 3) magnetic resonance imaging of the inferior vena cava and pelvic vessels or computer (multispiral) tomography of the abdominal organs with contrast; 4) phlebography of the renocaval and ileocaval segments.Results. The variant anatomy of fibrous and fibro-osseous canals (tunnels) can explain the fact that with equally pronounced expansion of the pelvic veins, some patients have pelvic symptoms due to nerve compression, while the other part does not. This concept is supported by the fact that in those patients who had complaints of pain, dysuria and erectile dysfunction, after surgical treatment of pelvic varicose veins, in most cases they disappeared or decreased.Conclusion. Pain syndrome (56.6 % of cases), erectile dysfunction (51 % of cases) and dysuria (17.9 % of cases) were noted as clinical manifestations in patients with pelvic varicose veins. Analysis of data after examination and treatment of patients with pelvic varicose veins allowed us to identify “venous compression neuropathy syndrome” as a probable cause of the development of pelvic symptoms in patients with pelvic varicose veins. Depending on the level of localization of nerve compression by varicose veins, we proposed to distinguish three forms of this syndrome: 1) thoracic, 2) lumbar, and 3) sacral form.
