title: Massive intraperitoneal hemorrhage from ruptured corpus luteum during anticoagulant therapy.
abstract: The unpredictability of hemorrhagic complications during anticoagulant therapy is well known. An unusual case of massive intraperitoneal hemorrhage from a ruptured corpus luteum during such therapy is presented. That this complication is uncommon may be  because relatively few premenopausal women are placed on anticoagulant therapy. In addition, the most likely condition for which premenopausal women are given anticoagulants is thrombophlebitis associated with pregnancy and childbirth when ovulation is inhibited.
