Application of oxytocin in ultrasound-guided percutaneous microwave ablation for treatment of hypervascular uterine fibroids: a preliminary report

Figures & data

Table 1. Characteristics of patients in both treatment groups.

	Oxytocin	Control
Age (years)	38.3 ± 4.3	39.2 ± 4.1
Number of fibroids (n)	19	19
Volumes (cm^3)	89.6 ± 36.7	89.9 ± 37.3
Location in uterus (n)
Intramural	14	14
Subserosal	2	2
Submucosal	3	3

Data were presented as mean ± standard deviation or n number of fibroids.

Figure 2. CDU showed hypervascular fibroids (A) before oxytocin administration (Adler grade 3); (B) after 20 min of intravenous oxytocin administration. Blood supply of myoma decreased to Adler grade 0.

	Oxytocin	Control
Major axis, cm^a	4.42 ± 0.45	3.78 ± 0.51
Anteroposterior diameter, cm^b	3.91 ± 0.42	3.29 ± 0.43
Left and right diameter, cm^c	4.28 ± 0.41	3.55 ± 0.39
Volume, cm^3 ^d	36.96 ± 2.78	22.68 ± 3.38

Data were presented as mean ± standard deviation.

^a The longest upper and lower diameter of the myoma in the sagittal plane.

^b The longest anterior and posterior diameter of the myoma in the sagittal plane.

^c The longest left and right diameter of the myoma in the axial plane.

^d t = 12.68, p = 0.001.
