Unilateral uterine artery embolization and Bakri tamponade balloon insertion in the treatment of acute puerperal uterine inversion: a case report

Abstract

Background Acute puerperal uterine inversion is rare but may cause massive postpartum blood loss due to uterine atony. Therefore, these patients must be diagnosed, and uterine replacement must be performed as soon as possible. However, in some cases, active bleeding due to uterine atony becomes uncontrollable, even though the uterine inversion itself is treated. In these cases, additional treatments, including surgical procedures, are needed. Case presentation A 41-year-old Japanese woman, gravida 1, para 0, was hospitalized for labor induction at 40 weeks and 3 days of gestational age. She had a vacuum-assisted delivery after 3 days of oxytocin administration, but acute uterine inversion occurred. Although replacement of the inverted uterus was successful by manual repositioning and Bakri balloon tamponade insertion, massive postpartum hemorrhage caused by uterine atony became uncontrollable. In this situation, since disseminated intravascular coagulation had developed, we used uterine artery embolization to stop the bleeding. After detecting the pseudo-aneurysmal sac and tortuous vessels of the right uterine artery, transcatheter right-sided uterine artery embolization was performed. Thirteen days after uterine artery embolization, she was discharged with no complications. Conclusions In cases of disseminated intravascular coagulation caused by massive postpartum bleeding, uterine artery embolization may often be selected. In our case, since we performed angiography to detect the main bleeding site, the hemorrhage could be stopped with unilateral uterine artery embolization alone, without hysterectomy.
