Aortic Aneurysm
Conditions
Brief summary
Retrospective study to evaluate the impact of computational wall stress analysis based on computed tomography (CT) of ruptured and not-ruptured aortic aneurysms as an additional predictor for rupture with dedicated software.
Detailed description
In patients with known aortic aneurysm who received clinically indicated CT during a time period from 01/2004-12/2013 the CT data was evaluated with dedicated software, A4clinics, VASCOPS GmbH, Graz, Austria. The following parameters will be evaluated: exterior and luminal diameter, intraluminal thrombus (ILT) thickness, vessel-, luminal- and intraluminal thrombus volume, peak wall stress (PWS), peak wall rupture risk (PWRR), von Mises-stress and rupture risk-index in the ILT.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| To calculated the rupture risk equivalent diameter (RRED) of the aortic aneurysm and rupture risk-index in the intraluminal thrombus within the aortic aneurysm. | CT Data from 01/2004-12/2013 | By using the finite analysis from the CT data the peak wall stress (PWS), the peak wall rupture (PWRR) and the mises stress within the aortic aneurysm depending on the diameter and volume of the aortic aneurysm and of the intraluminal thrombus will be measured. |
