Balloon tamponade is an effective intervention for managing postpartum hemorrhage, particularly in resource-limited settings. However, cervical relaxation during balloon insertion may cause balloon slippage, resulting in placement failure. This complication is associated with increased blood loss, a higher risk of hysterectomy, and unnecessary use of resources.

We conducted a retrospective analysis of 10 patients who underwent modified cervical cerclage balloon fixation combined with cervical clamping for postpartum hemorrhage complicated by balloon slippage. These patients were treated between January 1, 2021, and January 1, 2024, at two hospitals in Cheng Du and Xizang, China. The primary outcome was successful hemostasis following intervention. Secondary outcomes included perioperative blood loss and drainage volume. Data analysis was performed using descriptive statistics and the Shapiro-Wilk test.

The modified method was applied in 10 patients. Hemostasis was successfully achieved in 9 of 10 cases (90%). In 1 patient, additional uterine artery embolization was required due to an arteriovenous fistula.

Modified cervical cerclage balloon fixation combined with cervical clamping is an effective and low-cost approach for preventing balloon slippage in appropriate clinical settings.
