Non-aortic aneurysms Natural history and recommendations for referral and treatment

Background Non-aortic aneurysms constitute a collection of conditions where the same pathology presents in multiple anatomic locations. They are often detected incidentally and the aetiology, natural history, clinical presentation and treatment of non-aortic aneurysms may differ completely, depending on their site. Objective This article summarises current knowledge about non-aortic aneurysms in a structured manner, highlighting the natural history and recommendations for referral and treatment. Discussion Non-aortic aneurysms have an underestimated morbidity and mortality risk, and elective treatment has been demonstrated to prevent complications such as rupture or embolisation. Although endovascular repair has become increasingly popular, conventional open surgical repair has continued to play a substantial role in the treatment of non-aortic aneurysms: Treatment must be tailored to the patient and anatomic location, and early counselling and assessment by a vascular specialist is recommended.
