The effects of daflon on pelvic pain in women with Taylor syndrome

The syndrome of chronic pelvic pain without an obvious pathology has been described as pelvic congestion (Taylor) syndrome. It is frequently associated with continuous bilateral lower abdominal pain and dyspareunia. Pelvic examination reveals tenderness without induration or masses. Although their importance in the pathophysiology of pain is uncertain, prominent enlarged broad ligament veins are observed at laparoscopy. We evaluated the effects of daflon, a venomimetic agent that regulates the circulatory tonus of the venous system, on pelvic pain and investigated the role of enlarged veins in the pathophysiology of Taylor syndrome. Ten women (age 28-35 yrs) with chronic pelvic pain were diagnosed with the syndrome at laparoscopy. They all had prominent broad ligament and ovarian veins without other pathologies such as endometriosis to explain the etiology of pelvic pain. Five women were randomized in a double-blind fashion to receive daflon 500 mg twice/day for 4 months, and five a vitamin pill placebo; they were crossed over for another 4 months. They scored the frequency and severity of lower abdominal pain and dyspareunia on a scale from 0 to 6, and the results were compared with pretreatment values. At the end of the fourth month the frequency and severity of pelvic symptoms began to decrease with daflon compared with pretreatment and placebo. The mean scores were significantly less at the end of 4 months (9.3 ± 1.1 vs 4.2 ± 1.4, respectively, p
