Ruptured Abdominal Aortic Aneurysm Management (ESVS 2024)
Ruptured Abdominal Aortic Aneurysm Management (ESVS 2024): Suspected Ruptured AAA → Rapid Clinical Assessment → Permissive Hypotension.
Pathway Overview
16 steps
Algorithm Steps
16 total
01Start 02Action Rapid Clinical Assessment
Time-critical - mortality increases hourly
- Classic triad present in ~50%
- Abdominal or back pain (often sudden)
- Hypotension or hemodynamic instability
- Known AAA or pulsatile abdominal mass
- Risk factors: age >65, male, smoking, HTN, family hx
03Warning Permissive Hypotension
Target SBP 70-90 mmHg if conscious
- Avoid aggressive fluid resuscitation
- Target SBP 70-90 mmHg if patient conscious
- Higher target if neuro symptoms
- Prevents clot disruption
- MTP on standby - do not over-transfuse initially
04Decision Hemodynamic Status
Determines imaging vs direct to OR
05Warning Hemodynamically Unstable
Direct to OR - no imaging
- Refractory hypotension despite resuscitation
- Cardiac arrest or peri-arrest
- Skip CT - go directly to OR
- Aortic occlusion balloon (REBOA) if available
- Open repair or EVAR based on surgeon preference
06Action Open Surgical Repair
Required if EVAR not feasible
- Midline laparotomy
- Proximal aortic control (suprarenal or infrarenal)
- Tube graft or bifurcated graft
- Damage control surgery if unstable
- Higher short-term mortality but durable
07Action Intraoperative Considerations
Critical management points
- Massive transfusion protocol (1:1:1)
- Cell salvage if available
- Hypothermia prevention
- Acidosis correction
- Consider leaving abdomen open (ACS risk)
08Action Post-Operative ICU Care
Intensive monitoring for complications
- Abdominal compartment syndrome monitoring
- Colonic ischemia (10-20%) - sigmoidoscopy if concern
- AKI - monitor UOP, avoid nephrotoxins
- Cardiac events common
- Lower limb perfusion checks
09Warning Abdominal Compartment Syndrome
Suspect if rising IAP, oliguria, resp failure
- Monitor bladder pressure
- IAP >20 mmHg with organ dysfunction = ACS
- Decompressive laparotomy if ACS
- Temporary abdominal closure
- Occurs in 10-30% of open repairs
10Outcome Survival
30-day mortality 30-50%; better with EVAR if suitable
11Warning Colonic Ischemia
Common complication - high mortality
- Occurs in 10-20% of cases
- Suspect if bloody diarrhea, sepsis, metabolic acidosis
- Sigmoidoscopy for diagnosis
- Colectomy if transmural ischemia
- Higher risk: IMA ligation, hypotension, prior sigmoid disease
- Path rejoins step 10Shared downstream outcome
12Action Acute Kidney Injury
Common - multifactorial
- Occurs in 20-40%
- Hypotension, contrast, suprarenal clamp
- Avoid nephrotoxins
- RRT if indicated
- Often recovers if patient survives
- Path rejoins step 10Shared downstream outcome
13Outcome Mortality
30-50% overall; 100% without intervention
14Action Endovascular Repair (EVAR)
Recommended if anatomically suitable (Class I)
- Lower 30-day mortality vs open (IMPROVE trial)
- Percutaneous or cut-down access
- Aortouniiliac + fem-fem bypass if needed
- May need aortic occlusion balloon as bridge
- Consider local anesthesia if unstable
- Path rejoins step 07Shared downstream outcome
15Action CT Angiography
If hemodynamically stable - rapid protocol
- Confirms diagnosis
- Determines EVAR anatomic suitability
- Shows rupture location (retroperitoneal vs free)
- Must be performed rapidly (<30 min)
- Do not delay if deteriorating
16Decision EVAR Anatomically Suitable?
Assess neck length, angulation, iliac access
- Infrarenal neck ≥10-15mm
- Neck angulation <60°
- Adequate iliac access
- Graft availability
- Team expertise
- Path rejoins step 14Shared downstream outcome
- Path rejoins step 06Shared downstream outcome

Individual patient factors may require deviation from these recommendations.
Known Limitations
- Mortality 30-50% even with optimal treatment
- Requires immediate vascular surgery and OR availability
- EVAR requires suitable anatomy - not all patients eligible
- Permissive hypotension contraindicated if neurological symptoms
- Post-op complications common: ACS, colonic ischemia, AKI
