Pelvic congestion in women: evaluation with transvaginal ultrasound and observation of venous pharmacology

Abstract
Fourteen women with chronic pelvic pain due to congestion underwent transvaginal ultrasound scanning to observe changes in the diameters of dilated pelvic veins. Spontaneous fluctuations were observed, and intravenous dihydroergotamine resulted in a consistent venoconstrictor response (p = 0.0021) during 20min observation. Transvaginal ultrasound is useful for imaging dilated pelvic veins and for the study of venous pharmacology.
