Uterine Vascular Anomalies: Management and Treatment Overview

Abstract

Uterine vascular anomalies (UVAs), while rare, can result in severe, life-threatening hemorrhage. An understanding of the presentation and management options for UVAs is important for interventional radiologists to appropriately evaluate and care for these patients. The authors propose a standardized terminology for UVAs to avoid confusion and conflating congenital from acquired vascular lesions, which have a different pathophysiology. Limited high-level evidence and no definitive guidelines for UVA management exist, although endovascular treatment with uterine artery embolization has generally become the first-line approach for symptomatic or persistent UVAs with high technical and clinical success rates. There is also no consensus on the optimal embolization technique; the authors propose an initial approach to first embolize the dominant uterine artery supplying the UVA with gelatin sponge, with the option to embolize the contralateral side at the time of initial embolization if there is persistent supply (avoiding bilateral empiric embolization). Repeat embolization is feasible and recommended in the setting of recurrence, and both clinical and imaging follow-up is important. Ultimately, a multidisciplinary approach with individualized patient management is needed, particularly in the face of a lack of consensus guidelines for the management of symptomatic UVAs.
