Novel Use Of Contrast-Enhanced Sonography In The Diagnosis Of Central Uterine Necrosis Following Embolization For Postpartum Hemorrhage

Since 2007, we have identified 2 cases of central uterine necrosis after uterine arterial embolization for postpartum hemorrhage. Contrast-enhanced sonography showed an absence of enhancement of the internal myometrium. Magnetic resonance imaging with gadolinium confirmed the diagnosis. The images obtained for the first case were corroborated by histologic analysis from a hysterectomy done for sepsis. For the second, case, contrast-enhanced sonography performed during a follow-up period of conservative treatment revealed a reduction of necrosis. Our study shows that contrast-enhanced sonography seems to be a useful examination as an adjunct to grayscale and power Doppler imaging in the diagnosis and follow-up of uterine necrosis.
