I read the comments of Dr Singer with great interest. Because of disunity of the patient's care among several institutions, no clotting studies were obtained. I cannot say, however, that the persistent bleeding was not related to puncture of the uterus with the sound in the presence of anticoagulants. Although surgery is performed frequently on patients receiving anticoagulant agents, bleeding points are ligated or electrocoagulated. In this instance, a uterine puncture that would have stopped bleeding spontaneously, as evidenced by common experience with punctures during routine curettages, did not stop bleeding for 72 hours, and the only outstanding factor was the administration of anticoagulant medication. Therefore, I believe that anticoagulation constitutes a relative contraindication for intrauterine-device insertion.
