Assessment of uterine fibroid infarction after embolization with tris-acryl gelatin microspheres

Figures & data

Figure 1. (A) Presents contrast-enhanced MRI of the fibroid prior to UFE. (B) Presents the same fibroid after UFE with complete fibroid infarction (100%) without residual contrast enhancement. Category 1.

Figure 2. (A) Presents contrast-enhanced MRI of the fibroid prior to UFE. (B) Presents the same fibroid after UFE with almost complete fibroid infarction (90–99%) and residual contrast enhancement below 10%. Note small irregularity on the base of embolized fibroid. Category 2.

Figure 3. (A) Presents contrast-enhanced MRI of the fibroid prior to UFE. (B) present the same fibroid after UFE with incomplete fibroid infarction (<90%) and with residual contrast enhancement over 10%. The central part of the fibroid is with residual contrast enhancement. Category 3.

Table 1. Patients symptoms and MRI characteristics

Dominant symptom and MR characteristics	Number of patients/percentage
Patients symptoms	• Predominantly bleeding—11 (42%) • Predominantly bulk-related symptoms—5 (19%) • Both (bleeding and bulk-related)—10 (39%)
Dominant fibroid localization	• Intramural—23 (88%) • Subserosal—2 (8%) • Submucosal—1 (4%)
Number of fibroids	• 1 fibroid—10 (38%) • 2–5 fibroids—13 (50%) • >5 fibroids—3 (12%)
Uterus volume prior to UFE—cm³	Median/range
	500.3 cm³/ (93.7–1,149.2 cm³)
Dominant fibroid volume prior to UFE—cm³	Median/range
	186.3 cm³ (26.4–484.1 cm³)

Figure 4. (A) Presents fibroid prior to UFE. The left uterine artery was not embolized due to small calibre. (B) Presents almost complete fibroid vascularization from the right uterine artery. (C) Presents control contrast enhancing MRI with complete fibroid infarction despite the left uterine artery was not embolized.

Figure 5. The median changes in the HRQOL and symptoms severity score. (A) Significant increasing in HRQOL after UFE (p < 0.001). (B) Significant decreasing of symptoms severity score (p < 0.001).
