title: Arteriovenous malformations of the uterus associated with medical abortion.
abstract: Seven cases of uterine arteriovenous malformations associated with pregnancy were initially suspected by the history of prolonged bleeding after a medical abortion and then confirmed by color Doppler scanning. All cases were managed expectantly and resolved spontaneously. When AVMs required diagnosis by pathology or angiography, only the most severe cases would have been reported. Now that they can be recognized on ultrasound, it is possible that mild cases such as these will be found to be much more common.
