Uterine Artery Embolization of Uterine Arteriovenous Malformation: A Systematic Review of Success Rate, Complications, and Posterior Pregnancy Outcomes.

Uterine Arteriovenous Malformation (UAVM) is a rare but life-threating cause of uterine bleeding. The clinical management of this condition is challenging, and there is a need to describe the most adequate approach for these patients. Uterine artery embolization (UAE) is the most widely-published treatment in the literature in recent years, although there is a need to update the evidence on this treatment and to compare it with other available therapies. Thus, the objective of this systematic review is to quantify the efficacy of UAE of UAVM. In addition, we evaluated the clinical context of the patients included, the treatment complications, and the pregnancy outcomes after UAE. With this goal in mind, we finally included 371 patients spread over all continents who were included in 95 studies. Our results show that, similar to other medical therapies, the global success rate after embolization treatment was 88.4%, presenting a low risk of adverse outcomes (1.8%), even in women with later pregnancy (77% had no complications). To date, this is the largest systematic review conducted in this field, although there are still some points to address in future studies. The results obtained in our study should be outlined in UAE protocols and guidelines to aid in clinical decision-making in patients with UAVM.
