Emergency surgery for abdominal aortic aneurysms (AAA) carries a high mortality risk, particularly in patients with preoperative shock. Elective AAA repair shows significantly lower mortality rates.

Area of Science:

  • Vascular Surgery
  • Aortic Aneurysm Research
  • Surgical Outcomes Analysis

Context:

  • Abdominal aortic aneurysm (AAA) repair mortality varies significantly, especially in emergency settings.
  • Literature review indicates a wide mortality range (14-70%) for emergency AAA operations.
  • Retrospective analysis of 82 AAA patients provides subgroup-specific mortality data.

Purpose:

  • To analyze the mortality rates of abdominal aortic aneurysm (AAA) patients across different surgical subgroups.
  • To compare mortality between elective and emergency AAA repair.
  • To identify risk factors influencing AAA surgery outcomes.

Summary:

  • Overall 30-day mortality for elective AAA repair was 5%, with 0% for patients under 75.
  • Emergency AAA surgery had a 33% 30-day mortality rate.

  • Mortality was significantly higher in emergency cases with preoperative hypovolemic shock (52% vs. 9.5%).
  • Subgroup mortality varied: asymptomatic AAA (5.4%), symptomatic AAA (10%), retroperitoneal rupture (34%), and intraperitoneal rupture (66.6%).

    • Impact:

    • Highlights the critical impact of preoperative shock on emergency AAA surgery outcomes.
    • Demonstrates the improved safety of elective AAA repair, especially in younger patients.
    • Provides crucial data for risk stratification and surgical planning in AAA management.
