Measuring abdominal aorta diameter in women 50 and older
Official title: Studio Osservazionale Prospettico Multicentrico nazionAle Nel Sesso Femminile peR la valutaziOne Del DIametro Dell'aorTa addominalE - A National, Multicenter, Prospective Observational Study in Females to Assess Abdominal Aortic Diameter
Run by Fondazione IRCCS Ca' Granda, Ospedale Maggiore Policlinico · NCT07487961 · Data updated 2026-11-12
This project will measure abdominal aorta and common iliac artery sizes and collect reproductive and health history from women aged 50 and older to define typical diameters and identify female-specific risk factors for aortic disease.

Is this trial a fit for you?
✓Likely a good fit
Women aged 50 years or older who can provide informed consent and who have no prior diagnosis of thoracic or abdominal aortic aneurysm and no prior aortic surgery are ideal candidates.
✕Probably not a fit
Women under 50, those with a prior aortic aneurysm diagnosis or prior open or endovascular aortic surgery, and individuals unable to consent are excluded and unlikely to benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
Women aged 50 and older without prior aortic aneurysm or aortic surgery will be enrolled and undergo ultrasound measurement of the abdominal aorta and common iliac arteries using standard perpendicular probe placement with inner-to-inner and outer-to-outer caliper recordings. Measurements will include antero-posterior and lateral diameters and documentation of thrombus or calcification. Investigators will also collect demographic, pathophysiological, and reproductive history data including menarche, pregnancy/infertility, and menopause. The primary goal is to define ultrasound reference diameters in the female population and secondarily to identify sex-specific risk factors for abdominal aortic disease.
Why it matters
Potential benefit: If successful, this work could establish female-specific aortic diameter reference ranges and help identify women at higher risk of aneurysm or rupture, improving screening and treatment timing.
How similar studies have gone: Standard ultrasound measurement techniques are well established, but dedicated studies defining female-specific aortic diameter norms are limited, so this approach addresses a relatively understudied area.
