The angiogram obtained from the microcatheter revealed reflux of the contrast to the pseudoaneurysm from the distal artery (Fig. 4).

The Onyx  was slowly injected to occlude the uterine artery distal to the pseudoaneurysm, at the site of the pseudoaneurysm, and more proximally with good control of the flow; this obliterated the parent artery without leakage into the pseudoaneurysm, thus avoiding mass effect in the myometrium (Fig. 5).
22-year-old female with uterine artery pseudoaneurysm. DSA image demonstrates Onyx  slowly injected distal to the pseudoaneurysm to occlude the uterine artery and more proximally across the pseudoaneurysm. Note the Onyx  cast (black arrows).
