Webb12 apr. 2024 · Few contemporary reports show data on true prevalence rates and natural history. Recently, authors reported from the Danish Cardiovascular Multicentre Screening Trials (14 989 participants) a mean ascending aortic diameter of 37 mm in men and 34 mm in women. The reported prevalence of ATAA was ∼0.1% in both sexes. Webb26 mars 2024 · A simple parameter, called the Aneurysm number (An) which is defined as the ratio of transport to vortex time scales, has been shown to classify the flow mode in simplified aneurysm geometries.Our objective is to test the hypothesis that An can classify the flow in patient-specific intracranial aneurysms (IA). Therefore, the definition of this …
