    Abstract:
    BACKGROUND: Abdominal aortic aneurysm (AAA) is three to five times more common among men compared with women, yet up to 38% of all aneurysm related deaths affect women. The aim of this study was to estimate the prevalence of synchronous or metachronous aneurysms among women with AAA, as diagnosis and treatment could improve survival. PATIENTS AND METHODS: This is a retrospective study of prospectively registered patients. All women operated on, or under surveillance for, AAA were identified at two Swedish hospitals. Aneurysms in different locations were identified using available imaging studies. Aneurysms were defined according to location: thoracic ascending aorta ≥42 mm, descending ≥33 mm, abdominal aorta ≥30 mm, common iliac artery ≥20 mm or 50% wider than the contralateral artery, common femoral artery ≥12 mm, popliteal artery ≥10 mm. RESULTS: A total of 339 women with an AAA were included. The median follow up was 2.8 (range 0-15.7) years. Thirty-one per cent had an aneurysm in the thoracic aorta (67 of 217 investigated, 84% were located in the descending aorta), 13 (19%) underwent repair. Twelve per cent had a common iliac artery aneurysm (24/259, 76% were investigated). Common femoral artery aneurysms were identified in 4.3% (8/184, 54% investigated). Popliteal artery aneurysms were identified in 4.0% (6/149, 44% investigated). The prevalence of infrainguinal aneurysms was higher among patients with synchronous iliac aneurysms (40% vs. 1.6%, OR 42, 95% CI 6.4-279, p < .001). CONCLUSIONS: Thoracic aortic aneurysms are common among women with AAA, most commonly affecting the descending aorta, and detection frequently results in repair. Popliteal and femoral aneurysms are not rare among women with AAA, and even common if there is a synchronous iliac aneurysm.
