Glasgow Aneurysm Score (GAS)

Predicts perioperative mortality in elective and ruptured AAA repair (Samy 1994). GAS = age + 17(shock) + 7(MI) + 10(CVD) + 14(renal disease).

Score interpretation

Low mortality risk 60–80

→ Standard elective AAA repair pathway (EVAR preferred per NICE NG156). Cardio-pulmonary fitness assessment pre-op (CPET, echo).

Moderate mortality risk (~10–20%) 81–95

→ MDT discussion. Optimise comorbidities; consider EVAR if anatomy permits. Detailed informed consent. ITU bed planned.

High mortality risk (>30%) 96–200

→ Discuss best supportive care vs intervention. EVAR strongly preferred if intervention offered. Family meeting pre-op. If ruptured presentation — apply Hardman in parallel.
