Chronic abdominal aortic occlusive disease related to antiphospholipid syndrome: a rare presentation
Objective Chronic abdominal aortic occlusive disease (CAAOD) is an uncommon manifestation of antiphospholipid syndrome (APS), impacting cardiovascular health and peripheral arterial circulation. We investigated CAAOD in antiphospholipid antibodies (aPL)-positive patients, aimed to offer comprehensive clinical and radiological insights. Methods aPL-positive patients with arterial thrombotic events were categorised into CAAOD and non-CAAOD. Extensive data, including clinical features, radiological images and outcomes, were analysed. Results This case-control study involved 114 patients who experienced arterial events from 2013 to 2021, revealing 12 patients with abdominal aortic stenosis or occlusion. The CAAOD group, predominantly young (36.67±11.83) males (75.00%), exhibited significantly higher rates of critical smoking habits (66.67% vs 25.49%, p= 0.006 ) and hyperhomocysteinaemia (66.67% vs 31.37%, p= 0.026 ). Radiological findings showed long-segment infrarenal aorta stenosis in CA
