Abdominal aortic aneurysms (AAAs) are a serious and often silent vascular condition. Although women develop AAAs less frequently than men, they face higher complication rates, are more likely to rupture at smaller aneurysm sizes, and have significantly worse outcomes when rupture occurs.
The WARRIORS (Women's Aneurysm Research: Repair Immediately Or Routine Surveillance) trial compares two approaches to managing small AAAs (4.0–5.4 cm) in women aged 50 or older:
- Early Endovascular Aneurysm Repair (Early EVAR): A minimally invasive procedure performed while the aneurysm is still small
- Routine surveillance: Regular monitoring with repair offered if the aneurysm reaches 5.5 cm or larger (current treatment standard)
Participants are followed for five years, tracking survival, rupture rates, quality of life, and costs. The findings will directly inform future clinical guidelines for women with AAA.
