The natural history of abdominal aortic aneurysms (AAAs) renders them clinically silent for much of their evolution. These aneurysms will inevitably expand with time and, although surveillance programmes exist, an acutely ruptured AAA is still a relatively common clinical scenario. The classical presentation is with rapid haemodynamic deterioration with accompanying ...

Early detection of atherosclerotic renal artery stenosis (ARAS) is clinically important with respect to blood pressure control, prevention of renal insufficiency, and even improving survival. We investigated whether the presence of significant ARAS (luminal diameter narrowing ≥70%) could be predicted using a logistic regression model before coronary angiography/intervention. Initially, we ...

Thoracic endovascular aortic repair (TEVAR) is known to have a survival benefit over open repair in patients with descending thoracic aneurysms and has become a mainstay of therapy. Because death before 1 year after TEVAR likely indicates an ineffective therapy, we have created a predictive model for death within 1 ...
