Diagnosis of Ovarian Vein Syndrome (OVS) by Computed Tomography (CT) Imaging

Abstract

This article aims to explore the characteristics of computed tomography (CT) images of ovarian vein syndrome (OVS). The approval of the research ethics committee and the written informed consent of the patients were obtained. The CT images of 11 patients who had been diagnosed with OVS were retrospectively analyzed. All patients were examined with CT urogram, both plain CT scans and enhanced CT scans (including arterial phase, venous phase, and secretory phase). The datum was pulled into a computer workstation for post-processing. Ureteral obstruction at the position and ureteral dilation above it, where the ovarian vein crosses over the ureter, were found in all 11 patients. In addition, 4 patients presented with right upper ureteric calculi, 10 with right renal calculi (including 8 patients with multiple renal calculi that also had obvious uronephrosis), and 2 with a urinary calculus or cystolith. The diameter of the ovarian vein in them ranged from 5 mm to 13 mm. Varicose veins around the uterus were found in 2 patients, and the diameter of the left ovarian vein was larger than 7 mm in 1 patient.In conclusion, analysis of CT images is a vital method in diagnosing OVS.
