Use of Uterine Artery Embolisation for Pregnancy-related Complications: a Single-Institution Experience

Objective: To evaluate the indications, efficacy, and complications of uterine artery embolisation (UAE) in different pregnancy-related conditions. Methods: All patients who underwent UAE for pregnancy-related conditions from January 2008 to December 2013 in a regional hospital in Hong Kong were retrospectively reviewed. Indications for UAE, details of UAE procedure, success rate, and complication rate were analysed. Any reported pregnancy following UAE was also noted. Results: A total of 24 patients underwent 25 UAE procedures. In nine patients, 10 UAE procedures were performed for scar pregnancy and its related complications. In 15 patients, UAE was performed for postpartum haemorrhage. Angiographic success rate was 100% in both groups. The clinical success rate was 80% in the postpartum haemorrhage group. The overall complication rate was 16%. There were three (12.5%) documented subsequent pregnancies. Conclusion: Scar pregnancy and postpartum haemorrhage were the most common indications for UAE in pregnancy. UAE is safe and effective in managing these conditions.
