Delayed hemorrhage as a result of ruptured uterine artery pseudoaneurysm after transmyometrial oocyte retrieval: Management by transcatheter arterial embolization using N-butyl-2-cyanoacrylate.

Uterine artery pseudoaneurysm is a rare but potentially life-threatening complication that can occur after various uterine manipulations. A 34-year-old nulliparous patient with a previous history of four consecutive miscarriages with unknown etiologies underwent transmyometrial oocyte retrieval as a result of malpositioning of the right ovary. Six days later, she experienced massive vaginal bleeding after a day of intermittent bleeding and was transferred to our hospital. At triage, continuous bleeding from the cervical canal was observed. Color Doppler ultrasonography and three-dimensional computerized tomographic angiography revealed a ruptured pseudoaneurysm originating from the peripheral branch of the right uterine artery in the lower uterine segment. It was successfully treated by transcatheter arterial embolization with N-butyl-2-cyanoacrylate. Transcatheter arterial embolization with N-butyl-2-cyanoacrylate is a feasible option for uterus-preserving management of late massive hemorrhage resulting from a ruptured uterine artery pseudoaneurysm after transmyometrial oocyte retrieval.
