BackgroundAging changes the aorta in length, tortuosity and diameter. This is relevant in thoracic endovascular aortic repair (TEVAR) and in the long term follow up.Methods and resultsTwo groups of hundred patients 60°). A linear regression model was built to test the effect of age and gender on tortuosity. Tortuosity was more pronounced in the ≥ 65 compared to the ConclusionNormal DTA tortuosity increases with age. This is important to understand natural aging and for TEVAR planning and follow-up.
