Introduction:
We sought to determine the feasibility of REBOA placement under intravascular ultrasound (IVUS) guidance and to determine flow dynamics while undergoing aortic occlusion of non-compressible torso hemorrhage (NCTH) secondary to aortic branch vessel injury.
Methods:
Ten Sus scrofa swine underwent laparotomy to create an artificial arteriovenous shunt between a mesenteric vessel and the IVC to simulate ongoing hemorrhage with auto-resuscitation. An IVUS catheter was advanced to the level of injury. A full- or partial-REBOA was then deployed proximally under IVUS guidance. Continuous hemodynamic data were collected.
Results:
All devices were placed successfully using IVUS. Comparing full- and partial-REBOA, femoral pressures were decreased (34% vs. 95%), and carotid pressures were increased (276% vs. 144%). Shunt flow was 26% of baseline for full-REBOA and 75% for partial-REBOA.
Conclusion:
Endovascular localization and treatment of hemorrhage has potential to advance combat casualty care through delivery of interventional approaches in a mobile technique with IVUS.
