Abstract
OBJECTIVE: To retrospectively compare the imaging findings and the outcomes for patients with vascular uterine abnormalities (VUA) and to identify prognostic factors. MATERIAL AND METHODS: Between 2007 and 2012, 38 patients with vaginal bleeding and abnormal ultrasonographic (US) findings consistent with acquired VUA were consecutively included (mean age 31.6 years, range 19-62). Follow-up was 32 months in mean (1-78 months). Seventeen women (44.7%) started bleeding immediately after curettage, spontaneous miscarriage, trophoblastic disease, or section scars, with the remainder starting bleeding after 8 days to 2 years. All US, CT (n=2), MR (n=5) and angiographic (n=26) images were reviewed and compared to medical reports in order to identify severe VUA requiring treatment, and predictive factors. RESULTS: No information about severity was provided by US, MRI or CT. Twelve patients were successfully managed conservatively. Angiography identified 6 non-severe VUA, corresponding to an isolated uterine hyperemia, and 20 severe VUA, corresponding to an association of a nidus and early venous drainage. Recurrences were more often observed for severe VUA (p=0.001). The hemoglobin level was significantly lower (below 11 g/L) in these cases (p=0.004). Recurrences were significantly more frequently observed for patients with history of dilatation and curettage (p=0.02). Hysterectomy was performed for three patients only (8%). Among the women who wished to have children, 14 (77.8%) were pregnant after 9 months in mean (range 2-23). CONCLUSIONS: Recurrence happens more frequently after curettage and in case of anemia or severe VUA findings on angiography, justifying adequate embolization for these patients.
