title: Right ovarian vein drainage variant: is there a relationship with pelvic varices?
abstract: OBJECTIVE
  To correlate right ovarian vein (ROV) variations that drain into the right renal vein (RRV) with the presence of pelvic varices.
  
  
  METHODS
  Routine abdominal multidetector-row computed tomography scans of 324 women were analyzed for the presence and type of ROV variations in this retrospective study. The subjects were divided into 2 groups: those with ROV variations and those without such variations. The diameters of the subjects' ROV, left ovarian vein (LOV), and parauterine veins were measured. Pelvic varices and the presence and degree of ovarian vein reflux were noted and compared between the 2 groups. The chi2-test and the Pearson correlation test were used for statistical analysis.
  
  
  RESULTS
  Thirty-two (9.9%) of 324 women studied exhibited ROV variant that drained into the right renal vein, and the remaining subjects (90.1%) exhibited a normal pattern of ROV drainage that flowed directly into the inferior vena cava. Pelvic varices were identified in 59 (18%) of the subjects. Reflux was not observed in any patient without pelvic varices. Fifty-seven of 59 women exhibited ovarian vein reflux. In 56 of those 57 individuals, reflux occurred only in the LOV, and in 1 subject, reflux was noted predominantly in the ROV. No significant relationship between the presence of an ROV that drained into the right renal vein and pelvic varices was noted.
  
  
  CONCLUSIONS
  Although right-sided pelvic varices associated with right ovarian vein drainage variations are rare, anatomic variations of the right ovarian vein are not. This study did not find an association between the presence of right ovarian vein and pelvic varices.
