Cervin A, et al. - Researchers examined the prevalence of popliteal artery aneurysm (PA) among men with screening detected abdominal aortic aneurysms (≥ 30 mm, AAAs) and subaneurysmal aortic dilatation (25–29 mm, SAA). Further, they assessed the relationships between PA and the diameters of the aorta, iliac, and femoral arteries. Among a total of 19,820 65-year-old men who underwent screening between 2006 and 2017, 173 (0.9%) were diagnosed with AAA, and 149 were diagnosed with SAA (1.1% of those screened 2006–2013, eligible for this study). At least one PA of any size, 3.0% were ≥ 15 mm and 2.2% ≥ 20 mm, was detected in 14.2% of the examined cohort. This suggests that individuals with screening detected AAA and SAA show a high prevalence of PA. Findings suggest no correlation of PA with the aortic diameter in this cohort, where all had dilated aortas, while it showed correlations with peripheral and iliac artery diameters.
