Key result
Women with abdominal aortic aneurysms experience faster aneurysm growth and higher rupture risk at smaller diameters, highlighting the need to determine ideal elective repair thresholds.
Why the study?
Should abdominal aortic aneurysms in women be repaired at a lower diameter threshold?
Should abdominal aortic aneurysms in women be repaired at a lower diameter threshold?
This review emphasizes the need to re-evaluate the diameter threshold for elective AAA repair in women due to their higher rupture risk at smaller diameters compared to men.
May support lower AAA repair thresholds in women; extends sex-specific risk data but leaves open need for dedicated trials.
Abdominal aortic aneurysm (AAA) primarily affects male patients; however, female patients with AAA have a faster rate of aneurysm growth, have higher risk of rupture even at smaller diameters, and have worse outcomes following repair of ruptured and intact aneurysms. Furthermore, early natural history studies and randomized controlled trials evaluating surveillance versus repair in small aneurysms were conducted primarily in male patients. Therefore, there are limited data regarding the ideal threshold for elective repair of AAA in women, either by aortic diameter or by alternative measures. We review the existing literature regarding AAA in women and consider the most appropriate threshold for repair.

Deery et al. (2018) conducted a review in Abdominal aortic aneurysm. Elective repair at lower diameter threshold was evaluated. Women with abdominal aortic aneurysms experience faster aneurysm growth and higher rupture risk at smaller diameters, highlighting the need to determine ideal elective repair thresholds.
