AI-Native Scoping Reviews & Evidence Mapping

AAA risk is not just “age and diameter”: this review shows smoking as the dominant driver, diabetes as a paradoxically protective signal, and women as lower-prevalence but higher-risk patients once aneurysm develops. The full evidence map explains which biological, anatomical, genetic, and post-EVAR surveillance signals may move AAA risk assessment beyond diameter alone.

Abdominal aortic aneurysm is becoming less common in routine population screening, but prevalence remains sharply concentrated in older male smokers, first-degree relatives, and patients with vascular or cardiopulmonary disease. This review maps where AAA is now rare, where it is still unexpectedly frequent, and why future screening may need to become more targeted than universal.

Cystic adventitial disease is a rare but clinically important vascular mimic of atherosclerosis, aneurysm, and embolic disease — especially in younger patients with claudication and few cardiovascular risk factors. This SAIMSARA evidence map compresses scattered case-level evidence into a practical diagnostic and treatment roadmap, linking popliteal dominance, synovial/articular origin theories, imaging clues, recurrence risk, and surgical versus percutaneous strategies.
