Transradial and Transfemoral Uterine Fibroid Embolization Comparative Study: Technical and Clinical Outcomes

J Vasc Interv Radiol. 2020 Jan;31(1):123-129. doi: 10.1016/j.jvir.2019.08.016. Epub 2019 Nov 23.


Purpose: To compare clinical and technical outcomes of transradial (TRA) uterine artery embolization (UAE) with those of the transfemoral (TFA) approach.

Materials and methods: Consecutive patients who underwent UAE with TRA and TFA in an academic hospital between May 2014 and June 2018 were included in this study. The ability to perform the procedure as planned, complication rates, and reduction in uterine volume, fibroid enhancement, and symptomatic improvement were compared using descriptive statistics, Student t-test, and chi-square test.

Results: There were 91 patients in the TFA group and 91 patients in the TRA group, with 1 crossover to TFA due to vasospasm (1 of 91; 1%). The tallest patient in the TRA UAE group was 178 cm and 4 patients taller than 178 cm in the TFA UAE group. Larger particles (900-1,200 μm) were more often used in the TFA group than in the TRA group (P < .001). There were similar low rates of minor access site complications. In the TFA group (6 of 91, 7%), 5 patients had groin hematomas, and 2 patients had groin pain compared to the TRA group (5 of 91, 5%): in which 4 patients had transient focal occlusion of the radial artery and 1 patient had focal pain, all of which resolved with conservative management. There were similar rates of uterine volume reduction in 40% ± 17% in the TFA versus 36% ± 16% in the TRA group (P = .22) and no residual enhancement in 49 of 58 [84%] in the TFA group versus 66 of 77 [86%] in the TRA group (P = .84). There were similar reductions in modifying symptoms (60 of 64 [94%] in the TRA group; and 37 of 40 [93%] in the TFA group; P = NS) was noted at follow-up.

Conclusions: Transradial UAE in women up to 178 cm tall and transfemoral UAE have similar technical and clinical outcomes, with low rates of access site complications.
