Abstract
Abdominal aortic aneurysm (AAA) screening has contributed in the decrease of aneurysm related and all-cause mortality. The objective of our study is to present our experience from the only existing pilot AAA screening program in Greece. Men from both urban and rural areas in Central Greece, aged >60 years old without a previously known diagnosis of AAA were invited through the public primary health care units to participate to a screening program. Demographics, comorbidities, family history and anthropometric data were recorded. Aortic diameter values of >30 mm and common iliac artery (CIA) diameter values of >18 mm, were defined as aneurysmatic by ultrasound. The screening program included 1256 individuals (1256/1814; response rate 69%). The incidence of AAA and CIA aneurysm was 2% (25/1256) and 2.3% (29/1256), respectively. Increased age (P<0.042), tobacco use (P<0.006) and its duration (P<0.008) were related to higher incidence of AAA, while diabetes mellitus to lower one (P<0.048). Multivariate analysis showed that AAA was associated to longer duration of smoking (1.05, CI: 0.02-6.6; P=0.01). Statin and antiplatelet therapy were administrated in 40% (10/25) and 44% (11/25), respectively of individuals with AAA. An additional analysis was provided between subjects with AD of 25-30 mm and AD <25 mm. In multivariate analysis, no factor was associated to AD of 25-30 mm. The incidence of AAA and CIA aneurysm in Central Greece is 2% and 2.3%, respectively. Smoking duration was the strongest associated factor with AAA incidence. This provides to healthcare policy makers a strong valid point for the prevention strategies.
