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.
7例与妊娠相关的子宫动静脉畸形最初因药物流产后长时间出血的病史而被怀疑，随后经彩色多普勒扫描得以确诊。所有病例均采取期待治疗并自然消退。当动静脉畸形需要通过病理或血管造影进行诊断时，可能只会报告最严重的病例。既然现在可以通过超声识别它们，那么像这样的轻度病例可能会被发现更为常见。
