Our aim was to compare the immediate non perfused volume (NPV) ratio, the complication rate, the adenomyosis volume reduction ratio, the transformed symptom severity score (tSSS) improvement at follow-up between patients with transverse and longitudinal scar patients groups using scar-patch in magnetic resonance guided...

and materials 20 women (38.2±5.1 years) who underwent MR-HIFU ablation were divided into 2 groups: the transverse scar group (N=10) and longitudinal scar group (N=10). The immediate NPV ratio, adenomyosis volume reduction ratio and tSSS at 6 months follow-up were accessed. All complications and adverse events were investigated during ablation procedure and follow-up period

The volume of adenomyosis was 102.1ml ± 50.4 (57.0-162.0 ml) for the transverse scar group and 101.3ml ± 48.8 (46-152 ml) for the longitudinal scar group. The mean transverse and longitudinal scar size in length were 126.5 mm ± 49.2 and 111.8 mm ± 32.8, respectively. The NPV ratio was 72.1% ± 15.1 (57.5-100 %) in the transverse scar group and 69.4% ± 13.4 (58.5-100%) in the longitudinal scar group (p>0.05). The volume reduction ratio follow-up was 24.0% ± 18.2 (-4.5%-39.8%) for transverse scar group...

Our findings revealed no difference in treatment outcome between two groups. Therefore, we suggest that the scar-patch could be served efficiently in MR-HIFU treatment of adenomyosis patients with transverse and longitudinal abdominal scars.
