Cervical pregnancy: assessment with three-dimensional power Doppler imaging and successful management with selective uterine artery embolization.

Cervical pregnancy is frequently associated with extensive hemorrhage which, in severe cases, may be stopped only by hysterectomy. We report a case of an anembryonic cervical pregnancy diagnosed at 10 weeks, and associated with a large arteriovenous malformation. The patient was conservatively managed with simple selective uterine artery embolization. After embolization, her vaginal bleeding ceased and the level of serum beta-human chorionic gonadotropin decreased rapidly. No additional treatment was given. The patient's postoperative course was uneventful and the cervical mass had disappeared at the follow-up 4 months later. To the best of our knowledge, this is the first report of conservative management of cervical pregnancy simply by uterine artery embolization. The role of three-dimensional power Doppler ultrasonography in the assessment of cervical pregnancy and in monitoring the therapeutic response is discussed.
