Indications
- Blunt abdominal bleeding
- Pelvic bleeding
Rationale
- Temporary measure for haemorrhage control until definitive plan is made
- Buys time
- Helps control arterial bleeding - not arterial back bleeding or venous bleeding
What is it
- Retrograde Endovascular Balloon Occlusion of Aorta
- Via Femoral puncture
- Aorta divided into 3 zones
- 1 - Left subclavian artery to the coeliac artery
- 2 - Coeliac artery to the most caudal renal artery (no go zone)
- 3 - Extends distally from the most caudal renal artery to the aortic bifurcation
- Can be total, partial and intermittent
External marks
- Zone I – Xiphoid (approx 50cm)
- Zone III – Umbilicus (approx 40cm)
Risks
- Intimal flap with distal limb ischaemia
- Thromboembolism
- Infection
- Bleeding
- Deploying in wrong landing zone - inadvertent ischaemia
- Release of K rich deoxygenated blood upon deflation
