title: Sonographic diagnosis of postpartum pseudoaneurysms of the uterine artery: a report of 2 cases.
abstract: Two cases of post-partum uterine artery pseudoaneurysm are described, 1 after normal vaginal delivery and the other after Caesarean section. Both cases were complicated by heavy bleeding and treated with catheter embolization. A turbulent arterial-type velocity waveform with high peak velocity and forward end-diastolic flow was registered in the feeding vessel. The peak blood flow velocity was high in both cases. The resistance index in the uterine artery was lower in the affected side of the uterus. Three-dimensional angiosonography was used to calculate the volume of the lesion, demonstrate its shape, and identify the feeding vessel.
