To document immediate and short-term changes in uterine perfusion after uterine artery embolization (UAE).

Fifteen patients (median age, 42 years) underwent UAE with tris-acryl gelatin microspheres and a limited embolization protocol. Contrast-enhanced magnetic resonance imaging was performed before therapy and 1 hour (immediate), 48–72 hours (subacute), and a median of 5 months (short-term follow-up) after UAE to determine uterine and leiomyoma perfusion. Leiomyomas with a minimum diameter of 10 mm were included. Changes in regional (ie, fundus/body/cervix), zonal (ie, endometrium/inner/middle and outer myometrial layer), and leiomyoma perfusion were documented.

UAE was technically successful in all patients. Immediate contrast-enhanced MR imaging revealed ischemia of the uterine body and fundus. The endometrium and inner …
