Screening men over 65 for abdominal aortic aneurysms (AAA) significantly reduces rupture and related deaths. Early diagnosis through screening, especially in high-risk groups like coronary artery bypass grafting patients, can lower mortality rates.

Area of Science:

  • Vascular Surgery
  • Diagnostic Imaging
  • Public Health Screening

Background:

  • Ruptured abdominal aortic aneurysms (rAAA) cause significant mortality, particularly in older men.
  • Abdominal aortic aneurysms (AAA) share a high prevalence with coronary artery disease (CAD).
  • Screening men over 65 has shown promise in reducing AAA rupture and related deaths.

Purpose of the Study:

  • To assess the incidence of AAA in patients awaiting coronary artery bypass grafting (CABG).
  • To evaluate the feasibility of AAA screening in this high-risk population.
  • To determine the potential impact of early AAA diagnosis on perioperative outcomes.

Main Methods:

  • A cohort of 118 patients scheduled for CABG underwent abdominal aortic duplex ultrasonography.

  • An aortic diameter exceeding 2.6 cm was defined as abnormal, indicating potential AAA.
  • Detected aneurysms were managed through either immediate surgery or surveillance protocols.

    • Main Results:

    • The study detected 18 abdominal aortic aneurysms (15.3%) among the screened patients.
    • Five patients required surgical intervention, while 13 were placed under surveillance.
    • The mean age of AAA detection was 64.8 years.

    Conclusions:

    • Patients with symptomatic CAD exhibit a high incidence of AAA, posing perioperative rupture risks.
    • Integrating AAA screening into the routine work-up for coronary revascularisation is recommended.
    • Consider staged repair for AAAs exceeding 5.5 cm to mitigate rupture risk.
