Pelvic pain syndrome or pelvic congestion syndrome, with no apparent organic cause, is a common gynecologicaldisorder. Ovarian varix, one of the causes of this syndrome, presents a difficult diagnostic and therapeuticproblem, though surgical ligation of the ovarian vein is an effective method of treatment. Although ovarian veinembolization has been recently developed as a useful alternative, no previous reports have described thisprocedure in Korea. We report a case of pelvic pain syndrome successully treated by ovarian vein embolization.
