Volumetric magnetic resonance-guided high-intensity focused ultrasound ablation of uterine fibroids through abdominal scars: the impact of a scar patch on therapeutic efficacy and adverse effects.

ABSTRACT: To retrospectively compare the treatment success, therapeutic efficacy, and adverse effects of magnetic resonance-guided high-intensity focused ultrasound (MRgHIFU) treatment for uterine fibroid patients with and without abdominal scars.Seventy-six women who underwent treatment were divided into group 1 (patients with abdominal scars, which were covered with scar patches that prevents ultrasound energy from reaching the scar tissue immediately behind the patch) and group 2 (patients without abdominal scars). Non-perfused volume (NPV) ratios immediately after treatment, and fibroid volume reduction ratios and symptom severity scores (SSS) at the 6-months follow-up were assessed. All adverse effects were recorded.The mean NPV ratios in groups 1 and 2 were 87.0 ± 14.1% and 91.5 ± 13.3%. At the 6-months follow-up, the fibroid volume reduction ratios in groups 1 and 2 were 0.45 ± 0.27 and 0.43 ± 0.21, and the corresponding improvement in mean transformed SSS were 0.7 ± 0.39 and 0.79 ± 0.28, respectively. No serious adverse effects were reported. The minor adverse effects encountered in this study are likely related to the temperature increase in the near-field of the ultrasound beam path, which inevitably leads to skin burns, or far-field heat absorption by distant bony structures (i.e., sciatic nerve symptoms), and are typically manifested inter-procedurally and resolved shortly thereafter.The findings in this study suggest that the scar patch could be used safely and efficiently in MRgHIFU treatment for the patients with uterine fibroids and abdominal scars in the ultrasound beam path.

Project description:BACKGROUND:Uterine leiomyomas are common benign tumours found in women of reproductive age that are rarely associated with intra-abdominal haemorrhage. The aetiology behind this relationship is poorly understood and the aforementioned association poorly recognized from a patient's clinical presentation. Available information in the literature is limited to case reports. The aim of this systematic review is to document and highlight the occurrence of intra-abdominal haemorrhage from uterine fibroids, and determine associated morbidity and mortality. METHODS:A systematic review of Medline, EMBASE, Web of Science, Scopus, and The Cochrane Library - CENTRAL was performed from the databases inception through to December 2018 for case report and series of patients who experienced intra-abdominal haemorrhage from uterine fibroids. Findings were presented according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. RESULTS:We identified 115 publications reporting on 125 original case reports. The documented intra-abdominal haemorrhage were commonly due to the rupture of superficial blood vessels over the surface of a fibroid, followed by rupture and avulsion of the fibroid involved. A clinical picture of sudden and profound hypovolemic shock with severe abdominal pain was often the presenting complaint, with a correct pre-operative diagnosis only made in 7 cases on computed tomography imaging. Hysterectomy and myomectomy were the most common surgery performed. Mortality was reported in 4 cases which were directly related to complications of uterine fibroids. CONCLUSION:Intra-abdominal haemorrhage secondary to uterine fibroids remained a rare phenomenon which is poorly recognized among clinicians. While this association is not representative of the population of interest, it highlights the pathophysiological spectrum of uterine fibroids and its relevance to emergency physicians, surgeons and gynaecologists during clinical practice.
