Acute Hemoperitoneum, IUD, and Occult Ovarian Pregnancy

IUD users scored 3 of 9 ovarian pregnancies reported in Ottawa and its environs. There were also 7 instances of acme idiopathic hemoperitoneum of ovarian origin unrelated to IUD use; in 3 of these cases, suspicious of ovarian implantation were heightened by finding small clusters of chorionic villi in ovarian hematomas and gestational type hyperplasia in ovarian endometriosis. Such suspicions remain unconfirmed; in none of these cases was hemoperitoneal blood retained for laboratory procedures in order to identify the products of conception which, from ovarian implants, may be aborted in toto. Lest some unsuspected ovarian eccyeses go undetected, search for abortuses of ovarian origin in the hemoperitoneum should supplement microscopic examination of cystectomy or wedge resection specimens of ovary.
