Background:
Uterine arteriovenous communications are uncommon lesions that may be associated with life-threatening postpartum and postinstrumentation hemorrhage.
Case:
A primigravida presented with infected retained products of conception. Excessive hemorrhage of unclear etiology occurred at dilation and curettage. After a second episode of bleeding, the patient received a diagnosis of uterine arteriovenous fistula.
Conclusion:
Uterine arteriovenous communications should be included in the differential diagnosis in patients with excessive postpartum or postinstrumentation bleeding. Color and spectral flow Doppler can aid diagnosis and clinical management.
