Ultrasound diagnosis of uterine arteriovenous fistula associated with placental site trophoblastic tumor
2003
We report a case of a woman with abnormal vaginal bleeding who had a placental site trophoblastic tumor (PSTT) detected following hysterectomy. Surgery was performed because of a large uterine arteriovenous fistula detected by transvaginal color and pulsed Doppler sonography. Color Doppler sonography revealed a lacunar-type lesion with a marked increase in uterine vascularity, and pulsed Doppler sonography demonstrated a low resistance index. This vascular pattern indicated the formation of blood lacunae and arteriovenous shunts caused by PSTT within the uterine myometrium. This is the first report to describe the ultrasound findings in a case of PSTT complicated by a uterine arteriovenous fistula. Copyright © 2003 ISUOG. Published by John Wiley & Sons, Ltd.
