Predictive factors for success in uterine fibroid embolisation

A search of patient and procedural variables is performed to better understand the 10% failure rate of uterine fibroid embolisation (UFE) and what factors may contribute to decreased success in UFE. Statistical analysis of demographic and procedural factors associated with UFE was performed at two separate centres. 300 women were treated in approximately equal numbers for menorrhagia or post menopausal bleeding at two Los Angeles hospitals, a university centre and a community hospital. We did a comparison of success and failure groups by all demographic and procedural variables recorded. Both groups were statistically analysed. No demographic factors were predictive of success for UFE. Both centres had similar success rates. The pre-procedural total uterine volume was not associated with failure. However, pre-procedural diameter of the largest fibroid > 8.5 cm was predicative of failure.
