Abstract [en]

Objective: Few countries offer organized screening of siblings of patients with abdominal aortic aneurysms (AAAs), although a hereditary trait is well known to exist. Male relatives, but not female, are invited within the population-based screening programs for elderly men in Sweden. Evidence regarding the optimal age to screen siblings is scarce. The aim of this study was to describe the age at detection in siblings found with AAAs. Methods: All patients treated for AAAs in two Swedish counties were screened for siblings. Consenting siblings aged 80 and younger were examined (N = 529) with ultrasound and were interviewed per protocol. Results: In the cohort of 529 siblings to AAA patients, 53 siblings were diagnosed with AAAs (sisters 16/276 [5.8%] and brothers 37/253 [14.6%]). The prevalence of AAAs in the siblings 65 years of age or younger was 16/207 (7.7%). One-third of the siblings found with AAAs were young (16/53 [30%]). Among the young siblings with AAAs, 8/16 (50%) had an aneurysm larger than 50 mm or were already surgically treated. The prevalence of AAAs in siblings older than 65 years of age was 37/322 (12%). Conclusions: The AAA prevalence in this sibling cohort is strikingly high compared to the prevalence in the population (in Sweden, 1.4%-2.2% in 65-year-old men). The young ages among diagnosed siblings reinforce that male siblings of AAA patients should be screened before age 65 (before the population-based program) and that structured programs for female siblings are called for.
