Summary

Small abdominal aortic aneurysms typically grow over time. Regular ultrasound monitoring is crucial for patients managed non-operatively to track aneurysm diameter changes.

Area of Science:

  • Vascular Surgery
  • Diagnostic Imaging

Background:

  • Abdominal aortic aneurysms (AAAs) are a significant vascular condition.
  • Non-operative management is an option for smaller AAAs.
  • Monitoring aneurysm growth is essential for timely intervention.

Purpose of the Study:

  • To evaluate the growth rate of small abdominal aortic aneurysms.
  • To determine the necessity of regular ultrasound monitoring in non-operatively managed AAAs.

Main Methods:

  • Fifty patients with abdominal aortic aneurysms (2.5-5.0 cm) were initially managed non-operatively.
  • Aneurysm diameter was assessed using 6-monthly ultrasound examinations.
  • Growth rates and size increments were analyzed.

Main Results:

  • The median annual growth rate was 0.22 cm.
  • 77.8% of aneurysms increased in size over the study period.
  • Even aneurysms < 4.0 cm showed progression, with a maximum 6-monthly increment of 0.7 cm.

Conclusions:

  • Small abdominal aortic aneurysms demonstrate progressive growth.
  • Six-monthly ultrasound remeasurement is vital for non-operative AAA management.
  • This monitoring facilitates decisions regarding elective surgical intervention.
