What this trial studies

This is a multicenter, prospective, single-arm study in conflict-affected regions of Ukraine testing the AAJT-S abdominal aortic and junctional tourniquet as a temporary measure for severe PPH due to uterine atony that is refractory to uterotonics and intrauterine balloon tamponade. When eligibility is confirmed and standard measures have failed, the AAJT-S is applied to the upper abdomen and inflated to 250 mmHg to temporarily occlude the abdominal aorta and reduce pelvic blood flow. The study will collect feasibility, safety, and clinical effectiveness outcomes including control of bleeding, need for definitive surgery or hysterectomy, transfusion requirements, and device-related adverse events. The intent is to buy time to assemble surgical teams, initiate transfusion, and establish anesthesia where access to definitive care may be delayed.

Who should consider this trial

Good fit: Postpartum women aged 18 or older with primary PPH (estimated blood loss >1300 mL) from uterine atony that has not responded to uterotonics and balloon tamponade, who can provide oral informed consent prior to device application, are the intended candidates.

Not a fit: Patients whose bleeding is due to trauma, retained placental tissue, or primary coagulopathy (all exclusion criteria) are unlikely to benefit from this aortic compression approach.

Why it matters

Potential benefit: If successful, the device could rapidly reduce pelvic blood loss and buy critical time to reach definitive care, potentially lowering mortality, transfusion needs, and emergency hysterectomy rates.

How similar studies have performed: Aortic and junctional tourniquets have shown some success in trauma and emergency settings, but their use specifically for refractory PPH is relatively novel with only limited case reports and small series.
