Can uterine artery embolization be an alternative to plastic and reconstructive uterus operation by minimally invasive surgery?

Introduction: Plastic and reconstructive minimally invasive surgery has been established as gold standard in myomectomy. Therapy failure eventually leads to future surgical interventions or hysterectomy: surgeons and patients should be aware of the risks and benefits. We conducted a systematic review to analyse the evidence on the therapeutic indications and adverse events associated with uterine artery embolization and thereby evaluating if this method could be a valid alternative therapy. Methods: In concordance with PRISMA guidelines, literature research was made in PubMed, Cochrane Library, UpToDate, Amboss and Medline databases. Clinical trials, reviews and case reports published in English between January 2010 and June 2020 were included. Results: 44 articles were included out of 838 papers identified at initial search. Regarding uterine fibroids, three original papers and one Cochrane review reported the benefits of the procedure as an alternative to surgery, even in large and giant fibroids. Furthermore, several studies discussed the use of embolization for postpartum haemorrhage to decrease rates of hysterectomy after other haemostatic methods were exhausted, because of the potential risk of abnormal placentation in a future pregnancy. The procedure can also be successfully used as prophylactic method in different obstetrical procedures. Conclusions: The use of embolization in different uterine pathologies is a minimally invasive procedure as an alternative to surgery, especially in women who desire to preserve their uterus. Its related complications are described and can be avoided by a stringent indication of the procedure. More evidence regarding fertility after UAE, use of the procedure prophylactically in obstetrical haemorrhage or in adenomyosis is needed.
