Abstract

Objective(s)To evaluate whether ovarian vein incompetence may be a source of chronic pelvic pain (CPP) in women.Study designTwenty-two women, aged 19-50 years, with chronic pelvic pain, no laparoscopically detected pelvic pathology, and evidence of reflux in dilated pelvic veins on transvaginal color Doppler ultrasound underwent retrograde ovarian venography and sclerotherapy of the ovarian vein(s) if incompetent. The primary outcome was symptom change as assessed by a symptom questionnaire and visual analog pain scales (VAS) at 3, 6, and 12 months of follow-up. Changes in pelvic circulations after sclerotherapy procedure were also evaluated by serial ultrasound examinations. Differences between baseline and post-procedural VAS scores were analysed using the Wilcoxon signed-rank test.ResultsTwenty (91%) of the 22 women had venographic evidence of incompetent ovarian vein(s) and received sclerotherapy. There were no immediate or late complications. Variable symptom relief was observed in 17 (85%) of the 20 treated women, with follow-up at 12 months showing marked-to-complete relief in 15 patients and mild-to-moderate relief in the remaining 2 patients. Three (15%) women had no improvement in symptoms. Median VAS scores at 3 (2.0), 6 (2.5), and 12 months (3.0) were significantly lower than at baseline (8.0) (P<.001). Follow-up ultrasound examinations showed absence of pelvic venous reflux in all but 3 patients, in whom recurrence of reflux was seen at 3 months.Conclusion(s)Ovarian vein sclerotherapy provided symptomatic relief and improved pelvic circulation in most patients. These findings suggest that ovarian vein incompetence was the likely source of chronic pain in these women, and that sclerotherapy was a safe and effective treatment for this condition.CondensationOvarian vein incompetence leading to pelvic circulatory changes may be a cause of chronic pelvic pain in women.
