Pelvic venous changes after tubal sterilization.

We studied pelvic venous patterns after tubal ligation and compared them after different tubal sterilization procedures. To this end transuterine pelvic venography was performed preoperatively and after the first and sixth periods postoperatively in 56 women. All procedures that interrupt or interfere with the blood supply were analyzed in terms of uterine congestion, uterovaginal and ovarian varicosities and the incidence of pelvic venous stasis. There is a compelling need for a sterilization method that does not interrupt or damage the pelvic circulation; ideally it should be nonsurgical.
