PoCUS Spotlight: Abdominal Aortic Aneurysm (AAA)
PoCUS enables rapid bedside assessment of the abdominal aorta, helping clinicians identify aneurysms and recognize patients at high risk of rupture before catastrophic deterioration occurs.
A ruptured AAA is a silent killer — rapid recognition saves lives.
Why PoCUS matters
• Rapid bedside assessment
• Visualize the aorta from diaphragm to iliac bifurcation
• Measure outer wall to outer wall
▫️ ≥ 3 cm → aneurysm
▫️ ≥ 5 cm → high rupture risk
Key ultrasound pearls
• Aorta sits anterior to the spine
• Thick echogenic walls
• Non-compressible (unlike the IVC)
• Always scan in both transverse & longitudinal views
Clinical takeaway
AAA rupture → catastrophic hemorrhage → high mortality
PoCUS allows early detection and faster definitive care.
