During REBOA, the balloon is positioned above the bleeding site and inflated to reduce blood flow toward the injured region. This redistribution helps preserve circulation to the heart and brain while limiting ongoing distal hemorrhage. The benefit depends on maintaining the balloon position and using occlusion only as a temporary bridge.
Occlusion can reduce blood flow to tissues downstream from the balloon, creating a risk of ischemic complications if it continues too long. For that reason, clinicians must balance the need to support central circulation against the need to restore distal perfusion. Rapid balloon deflation is required once definitive hemorrhage control becomes possible.
The strategy is most relevant when severe internal bleeding occurs in a location that cannot be controlled effectively with external compression, especially in critically injured patients. Its value is greatest when temporary circulatory support is needed while clinicians move toward surgical or interventional treatment of the underlying hemorrhage.
Imaging helps clinicians guide and assess intravascular device placement, while continuous clinical monitoring helps evaluate the response to temporary aortic occlusion. These safeguards are important because the intervention must support pressure for the heart and brain without prolonging reduced distal flow. Decisions about maintaining or deflating the balloon therefore depend on both positioning and patient status.
The procedure begins with arterial access, followed by advancement of a balloon catheter through the vasculature into the aorta. Clinicians inflate the balloon above the hemorrhage to obtain temporary control, then continue monitoring while definitive surgical or interventional hemorrhage control is pursued. Balloon deflation must occur rapidly when ongoing occlusion is no longer necessary.
It functions as a bridge rather than a final treatment. By temporarily reducing blood flow below the occlusion site, the approach may stabilize circulation long enough for surgical or interventional teams to address the bleeding source. This makes timing central: the device supports resuscitation only until definitive control can be achieved.
Endovascular resuscitation addresses the challenge of managing critically injured patients with noncompressible torso hemorrhage, where bleeding may be difficult to control immediately. Its use combines intravascular device placement, circulatory support, imaging, and close monitoring. The intended outcome is temporary stabilization while clinicians establish more durable control of internal bleeding.
