Glasgow Aneurysm Score (GAS)
Predicts operative mortality in intact and ruptured AAA repair (Samy 1994). GAS = age in years + 17 (shock) + 7 (myocardial disease) + 10 (cerebrovascular disease) + 14 (renal disease).
Score interpretation
Prospective evaluation (Samy 1996, intact and ruptured AAA): 0 % operative mortality below 70.
→ Standard elective AAA repair pathway (EVAR preferred per NICE NG156). Cardio-pulmonary fitness assessment pre-op (CPET, echo).
Operative mortality rises with the score between 70 and 95 (Samy 1996).
→ MDT discussion. Optimise comorbidities; consider EVAR if anatomy permits. Detailed informed consent. ITU bed planned.
80 % operative mortality above 95 in the prospective evaluation (Samy 1996).
→ Discuss best supportive care vs intervention. EVAR strongly preferred if intervention offered. Family meeting pre-op. If ruptured presentation — apply Hardman in parallel.
