Biomechanical prediction of abdominal aortic aneurysm rupture risk: Sensitivity analysis
Objectives: The purpose of this research is to determine the quantitative relationship between the peak wall stress of abdominal aortic aneurysm (AAA) and its clinical risk factors including its maximum diameter, asymmetry index, wall thickness and abnormal high blood pressure. Methods: The response surface experimental design with one response and four variables was used to design the experime...
متن کاملAbdominal aortic aneurysm and risk of rupture.
370 residents of Rochester, Minnesota, with clinicallyrecognized unruptured abdominal aortic aneurysm (AAA), were identified through record review. The rolling entry period was 1951-1984. Of these 181 had at least one documenting ultrasound. Five persons had rupture of the aneurysm within 48 hours of the ultrasound exam, and were excluded from the study. The study group consisted of the remaini...
متن کاملAdvancements in identifying biomechanical determinants for abdominal aortic aneurysm rupture.
Abdominal aortic aneurysms are a common health problem and currently the need for surgical intervention is determined based on maximum diameter and growth rate criteria. Since these universal variables often fail to predict accurately every abdominal aortic aneurysms evolution, there is a considerable effort in the literature for other markers to be identified towards individualized rupture ris...
متن کاملPrediction of outcome after abdominal aortic aneurysm rupture.
BACKGROUND Most vascular surgeons practice a selective policy of operative intervention for patients with ruptured abdominal aortic aneurysm (AAA). The evidence on which to justify operative selection remains uncertain. This review examines the prediction of outcome after attempted open repair of ruptured AAA. METHODS The Medline and EMBASE databases and Cochrane Database of Systematic Review...
متن کاملBiological, Geometric and Biomechanical Factors Influencing Abdominal Aortic Aneurysm Rupture Risk: A Comprehensive Review
The current clinical management of abdominal aortic aneurysm (AAA) disease is based to a great extent on measuring the aneurysm maximum diameter to decide when timely intervention is required. Decades of clinical evidence show that aneurysm diameter is positively associated with the probability of rupture, but that other parameters may also play a role in causing or predisposing the AAA to rupt...
