Background. Screening for abdom­i­nal aor­tic aneu­rysm (AAA) has not yet been estab­lished in Japan. We there­fore ­report the char­ac­ter­is­tics of a ­screened pop­u­la­tion and dis­cuss the impli­ca­tions of screen­ing using ultra­sound in Japan.
Methods. The sub­jects in our screen­ing group were com­posed of 4428 par­tic­i­pants who were 60 years of age or older. Aneurysm was detect­ed in 16 cases, 15 males and 1 ­female, the detec­tion rate being 0.4% in total and 0.9% in the males. We com­pare the char­ac­ter­is­tics of ­screened ­patients (n=16) with non-­screened ­patients oper­at­ed on for abdom­i­nal aor­tic aneu­rysm (n=166).
Results. There were no sig­nif­i­cant dif­fer­enc­es in the mean age or in the ­female ratio between the ­screened and non-­screened ­groups (71 vs 70 y/o, 6% vs 13%, respec­tive­ly). Solitary iliac aneu­rysms were sig­nif­i­cant­ly (p<0.05) more fre­quent in the ­screened than in the non-­screened group (19% vs 3%). The size of aneu­rysm in the ­screened group was sig­nif­i­cant­ly (p<0.05) small­er com­pared with the non-­screened group. Sixty-three per cent of the ­screened group and only 8% of the non-­screened group had an aneu­rysm less than 40 mm in size. Aneurysm was pal­pa­ble in only 31% of those of the ­screened group. There were no sig­nif­i­cant dif­fer­enc­es ­between the ­groups in the fre­quen­cy of arte­rio­scle­rot­ic risk fac­tors such as hyper­ten­sion, ischaem­ic heart dis­ease, dia­betes mel­lit­us, periph­er­al vas­cu­lar dis­ease and smok­ing hab­its. Surgical treat­ment was select­ed in 7 out of 16 ­screened ­patients. The remain­ing 9 ­patients with small-sized abdom­i­nal aor­tic aneu­rysms have been care­ful­ly fol­lowed up.
Conclusions. Screening for abdom­i­nal aor­tic aneu­rysm using ultra­sound is advis­able espe­cial­ly for male par­tic­i­pants and for the detec­tion of iliac aneu­rysms. This screen­ing pro­ce­dure is use­ful for early detec­tion ­because the ­screened aneu­rysm is gen­er­al­ly small-sized and impal­pa­ble.
