Summary

Emergency surgery for symptomatic abdominal aortic aneurysms (AAA) within 24 hours has high early mortality. Delayed or elective surgery for non-ruptured AAA shows significantly lower mortality rates.

Area of Science:

  • Vascular Surgery
  • Aortic Aneurysm Research
  • Surgical Outcomes Analysis

Background:

  • Symptomatic, non-ruptured abdominal aortic aneurysms (AAA) present a surgical challenge.
  • Emergency open surgery for these conditions requires careful evaluation of outcomes.

Purpose of the Study:

  • To investigate symptoms and early mortality (<30 days) following open surgery for emergency, symptomatic non-ruptured AAA.
  • To compare outcomes between immediate emergency surgery and delayed/elective surgery for non-ruptured AAA.

Main Methods:

  • Retrospective cohort study of patients undergoing open surgery for non-ruptured AAA between 1983-1994.
  • Comparison of 30-day mortality between patients operated on within 24 hours of emergency admission versus those with delayed or elective surgery.

  • Analysis of co-morbidities and patient suitability for elective surgery.

    • Main Results:

    • Thirty-day mortality was 18% for patients undergoing emergency surgery within 24 hours for symptomatic non-ruptured AAA.
    • Mortality significantly decreased to 4.2% for delayed (semi-elective) or elective surgery (p=0.0002).
    • A proportion of patients who died after acute operations had previously been deemed unfit for elective surgery.

    Conclusions:

    • High early mortality in emergency non-ruptured AAA surgery is linked to co-morbidities and the acute nature of the operation.
    • Proposes distinct reporting categories for 30-day mortality: elective surgery versus surgery within 24 hours of emergency admission.
    • Suggests 'emergency non-ruptured' as a specific term for the latter group.
