Emergency and prophylactic uterine artery embolization in gynecology and obstetrics – a retrospective analysis
Abstract
Background. This study aimed to evaluate the safety and efficacy of emergency and prophylactic uterine artery embolization (UAE) in our clinical practice, including technical success, clinical success, and associated complications.
Patients and methods. In this retrospective study, we analyzed 64 women who underwent emergency (n =18) and prophylactic (n = 46) UAE. Indications for emergency UAE included postpartum hemorrhage or severe hemorrhage during pregnancy termination, while prophylactic UAE was performed prior to surgical removal of retained products of conception (RPOC), delivery with abnormal placental implantation, or pregnancy termination (cervical pregnancy or fetal anomalies accompanied by abnormal placental implantation). Technical success of UAE was defined as complete exclusion of the vascular lesion and contrast stasis on the final angiogram, while clinical success was defined as cessation of bleeding after UAE without a hysterectomy.
Results. The overall clinical success of UAE in our study was 97 % (62/64). All embolization procedures were technically and clinically successful in the prophylactic group without life-threatening hemorrhages or hysterectomies (100 % success rate, 46/46). However, while 100 % technical success was similarly attained in the emergency group, bleeding was successfully controlled in 89 % of cases (16/18). In two patients with significant blood loss (over 2000 mL), embolization failed to achieve hemostasis, resulting in persistent bleeding and subsequent hysterectomy.
Conclusions. UAE is a safe and effective procedure for managing primary postpartum hemorrhage or severe hemorrhage during pregnancy termination and for decreasing the risk of severe hemorrhage during surgical removal of RPOC, delivery with abnormal placental implantation, or pregnancy termination.
