Vacuum-Induced Tamponade for Treatment of Postpartum Hemorrh
Postpartum hemorrhage is the main cause of maternal mortality worldwide, with rising incidence, thus demanding new treatment approaches. Intrauterine balloon systems with the application of intrauterine vacuum are promising new methods.

All women treated with vacuum-induced tamponade using a modified balloon system were included in this single-center study. Aiming to reduce uterine size for control of postpartum hemorrhage, the intrauterine balloon was filled to 50–100 mL and connected to a vacuum device. The success rate of vacuum-induced tamponade, defined as no need for additional interventional treatment, was analyzed by etiology of postpartum hemorrhage and time period of use.

- Vacuum-induced tamponade was applied in 66 women. The success rate was 86% in women with uterine atony and 73% in women with postpartum hemorrhage due to placental pathology.

- Success rate improved over the study period, culminating in a success rate of 100% in women with postpartum hemorrhage due to uterine atony in the second half of the observation period.

This observational study supports the pathophysiologic understanding of uterine atony: to treat an atonic uterus, uterine volume must be reduced, leading to coiling of the uterine spiral arteries and, hence, reduced blood loss.
