Abdominal Aortic Aneurysm (AAA) growth rates increase with size. Smaller AAAs (3-4 cm) grew 0.215 mm/month, while larger ones (>5 cm) grew significantly faster at 0.78 mm/month.

Area of Science:

  • Vascular Surgery
  • Medical Imaging
  • Cardiovascular Research

Background:

  • Abdominal Aortic Aneurysm (AAA) is a serious condition characterized by the enlargement of the aorta.
  • Monitoring AAA growth rate is crucial for predicting rupture risk and guiding treatment decisions.
  • Ultrasound is a common non-invasive imaging modality for AAA surveillance.

Purpose of the Study:

  • To assess the growth rate of Abdominal Aortic Aneurysms (AAAs) based on their initial diameter.
  • To provide data that can inform clinical management strategies for AAA patients.

Main Methods:

  • Retrospective analysis of 86 patients diagnosed with Abdominal Aortic Aneurysm.
  • Abdominal ultrasound was used to measure aneurysm diameter and track growth over time.

  • Aneurysms were categorized into three groups based on diameter: 3-4 cm, 4-5 cm, and >5 cm.

    • Main Results:

    • The mean growth rate for aneurysms measuring 3-4 cm was 0.215 mm per month.
    • Aneurysms with a diameter of 4-5 cm exhibited a mean growth rate of 0.33 mm per month.
    • Aneurysms with an anteroposterior (AP) diameter greater than 50 mm showed a significantly higher mean growth rate of 0.78 mm per month.

    Conclusions:

    • AAA growth rate is positively correlated with aneurysm diameter.
    • Larger abdominal aortic aneurysms demonstrate accelerated expansion rates.
    • These findings underscore the importance of regular ultrasound monitoring for timely intervention in AAA management.
