AAJT-S Delivers Life-Saving Hemorrhage Control At A Civilian Level I Trauma Center
A Level I trauma case in which the AAJT-S delivered external aortic compression to a patient in hemorrhagic shock — stabilizing the patient within minutes to allow imaging and definitive surgical care.
Location: Medical University of Graz, Austria
Care team: Trauma center · Medical University of Graz, Austria
Setting: Hospital · Level I trauma center
Application site: Abdomen
Case ID: US-26-10
Clinical Case Summary
Synopsis
Injury, intervention, and outcome at a glance
- Traumatic pelvic fracture
- 3-story fall
- Hypotensive, tachycardic, deformed pelvis
- Hemorrhagic shock from intrapelvic bleeding
- Pelvic binder placed by EMS
- Patient arrives to trauma center in shock
- Massive transfusion protocol & vasopressors initiated
- SBP remained in 70s despite intervention
- AAJT-S applied to abdomen
- SBP rose >90
- Patient remained stable through imaging and damage control surgery
- No device-related complications or ischemia
- Discharged after 105 days in hospital
Catastrophic Blunt Pelvic Trauma
A 27-year-old female arrived at the Medical University of Graz emergency department after a 3-story fall. She was hypotensive with a BP of 70/30 and tachycardic at 148
MTP Initiated - Patient continues to deteriorate
A pelvic binder had been applied by EMS. Upon arrival to the ED, the team initiated a massive transfusion protocol and vasopressor support. The patient continued to deteriorate because the hemorrhage wasn’t controlled.
AAJT-S Applied to Abdomen
The AAJT-S was applied to the abdomen, compressing the descending aorta externally to occlude blood flow to the injury site. Within minutes, the patient’s systolic blood pressure rose from 70 to 90 mmHg.
Stable Through Imaging and Surgery — Discharged at Day 105
With the AAJT-S in place, the patient remained hemodynamically stable through CT imaging and damage control surgery. There were no device-related complications and no signs of ischemia. After 105 days in hospital, she was discharged neurologically intact.
“The case illustrates the utility of the AAJT as a life-saving intervention in the primary management of unstable patients with non-compressible pelvic hemorrhage.”
