Intraoperative microvascular assessment with contrast-enhanced ultrasound (CEUS) during uterine artery embolisation (UAE): a case report and literature review

The clinical success of uterine artery embolization is determined by its endpoint. An aggressive UAE could lead to endometritis and increases the risk of unintended embolization of other organs. Conversely, an incomplete procedure may result in a poor clinical outcome due to regrowth of the fibroids. We present a case with innovative use of intraoperative contrast-enhanced ultrasonography (CEUS) for the assessment of vascularity of the targeted fibroid to determine the endpoint of embolization perioperatively. We aim to report a case of the use of intraoperative CEUS during UAE to highlight the potential pitfall of its use and provide a review of its application in the literature. Our case affirms the reported usefulness and the practical feasibility to assess the vascularity of fibroids during UAE and highlights that caution should be made by operators in cases of multiple fibroids.
