Summary

Aneurysm size over 5 cm combined with a hyperattenuation crescent sign on CT scans can predict the risk of a ruptured abdominal aortic aneurysm, aiding clinical decision-making.

Area of Science:

  • Radiology
  • Vascular Surgery
  • Medical Imaging

Background:

  • Abdominal aortic aneurysms (AAAs) pose a significant rupture risk.
  • Predictive imaging biomarkers for AAA rupture are crucial for timely intervention.

Purpose of the Study:

  • To assess the utility of CT scan findings in predicting AAA rupture.
  • Specifically evaluating aneurysm size, hyperattenuation crescent sign, and mural calcification discontinuity.

Main Methods:

  • Retrospective review of 27 patients with AAAs requiring surgical repair.
  • Multislice CT (MDCT) images analyzed by two radiologists for aneurysm dimensions and specific signs.
  • Consensus review of imaging findings.

Main Results:

Related Experiment Videos

  • Ruptured AAAs had a mean maximum diameter of 6.95 cm vs. 5.50 cm in non-ruptured cases.
  • All ruptured aneurysms exceeded 5.0 cm in size.
  • Hyperattenuation crescent sign (95% specificity) and mural calcification discontinuity (100% specificity) strongly indicated rupture.

Conclusions:

  • An aneurysm size >5 cm with a positive hyperattenuation crescent sign is a significant predictor of rupture.
  • These CT findings can aid in risk stratification for abdominal aortic aneurysms.
