Leuprolide acetate treatment and myoma arterial size

Abstract

Intramyomatous arteries were smaller and more often showed arteriosclerotic changes in leiomyomas removed from women treated with GnRH-a compared with those given placebo. The estrogen deprivation induced by GnRH-a may cause a relative vasoconstriction of myomatous vessels. Whether this decreased vessel size is the principal contributor to decreased myoma size will require further study.
