Suspected acute aortic syndrome

Recognise a possible aortic dissection, avoid premature ACS treatment and coordinate urgent imaging, stabilisation and specialist transfer.

PAUSE BEFORE USING

This is an educational summary, not a point-of-care protocol. Follow current local emergency and medicines guidance and seek senior/specialist support.

FICTIONAL SCENARIO

A fictional 66-year-old with hypertension develops abrupt severe chest pain radiating to the back, a new pulse asymmetry and a 28 mmHg systolic blood-pressure difference between arms.

01 · RECOGNISE

Frame the danger first.

  • Abrupt severe chest, back or abdominal pain with pulse, blood-pressure, neurological or aortic-regurgitation findings should raise concern for acute aortic syndrome.
  • No single symptom or examination sign safely confirms or excludes dissection; combine history, examination and structured risk assessment.
  • A normal ECG or an elevated troponin does not resolve the differential between acute coronary syndrome and aortic disease.
02 · FIRST PRIORITIES

Act, escalate, reassess.

  1. Begin ABCDE assessment, monitoring, analgesia and immediate senior escalation while activating the local acute-aortic-syndrome pathway.
  2. Discuss definitive aortic imaging urgently with radiology and the accepting aortic team; use the locally agreed CT aortogram protocol when appropriate.
  3. Seek senior critical-care and cardiovascular guidance for controlled reduction of aortic wall stress, accounting for perfusion, aortic regurgitation and contraindications.
  4. Avoid reflex antiplatelet, anticoagulant or thrombolytic treatment until the competing diagnoses and bleeding risk have been assessed.
03 · ESCALATE NOW IF

Red flags that change pace.

  • Shock, syncope, tamponade physiology or rapidly changing haemodynamics
  • New focal neurology, limb ischaemia, mesenteric or renal malperfusion
  • New aortic-regurgitation features, heart failure or persistent severe pain
04 · COMMON ERRORS

What makes care less safe.

  • Calling the pain ACS before considering lethal alternatives
  • Waiting for troponin before arranging definitive imaging
  • Transfer without agreed blood-pressure, heart-rate, analgesia and deterioration instructions
05 · STRUCTURED HANDOVER

Say the concern plainly.

Suspected acute aortic syndrome with pain onset [time/pattern], haemodynamics [trend], pulse/BP/neurological findings [summary] and complications [present/absent]. Imaging and images are [status]; stabilisation is [status]. I need immediate aortic-centre advice and a safe transfer plan.
