Abstract No. 456 Radiation dose during uterine fibroid embolization in a major health care system: transradial vs. transfemoral access

Abstract

Transradial access (TRA) is now seen as an alternative to transfemoral access (TFA) for performing uterine fibroid embolization (UFE). To assess for non-inferiority of technique, our study compares dose area product (DAP) and fluoroscopy time (FT) after UFE between TRA and TFA across multiple hospitals in a single health system. All UFE cases performed from 7/2013 and 7/2018 in a large academic health system were reviewed. Patient demographics, clinical factors, and procedure characteristics were reviewed including patient age, DAP, FT, and access site. Adverse events were recorded. Statistical comparison between the TRA and TFA groups was performed with paired t tests. 387 UFE procedures were performed across five hospital sites (TRA n=313, TFA n =74) (Table 1). The median FT after TRA was 15.9 minutes and 17.7 minutes after TFA (p=0.14). The median DAP after TRA was 152503.5 mGycm2 and 228135 mGycm2 after TFA (p=0.12). There was no statistically significant difference between DAP and FT for UFE performed after TRA and UFE performed after TFA despite multiple sites and providers, although there was a trend towards lower DAP and FT with TRA.Table 1TRATFATotal patients31374 Site A19916 Site B445 Site C1107 Site D05 Site E01Fluoro time (min)15.917.7p=0.14Median dose (mGycm2)152503.5228135p=0.12 Open table in a new tab
