Doppler Sonography and 3D CT Angiography of Acquired Uterine Arteriovenous Malformations (AVMs): Report of Two Cases.

Uterine Arteriovenous Malformations (AVMs) are rare but life threatening causes of abnormal vaginal bleeding. Accurate clinical and radiological diagnosis is essential because uterine instrumentation that is often used for management of other sources of abnormal bleeding, can lead to massive hemorrhage. Timely diagnosis and early proper treatment can markedly reduce the associated disease mortality. Ultrasound with colour and spectral doppler is the initial imaging modality of choice. Three-dimensional computed tomography (CT) angiography can determine the actual extent of the vascular malformation and helps in pre-interventional planning noninvasively. Uterine AVM can be either congenital or acquired in nature with latter being more common. We hereby report two cases of acquired AVMs diagnosed by color doppler sonography and confirmed by three-dimensional CT angiography. Both the cases reported here had previous history of dilation and curettage for abortion. Clinically one patient presented with profuse uterine bleeding and another with meno-metrorrhagia and both cases underwent surgical removal of uterus.
