[Established Indications for Invasive Treatment of Thoracic Aortic Aneurysm].

Thoracic aortic aneurysms are associated with high morbidity and mortality due to rupture and dissection. Conservative medical treatment is associated with a 5-year survival rate of 13 %. This rises to 70-79 % in case of surgical treatment. While classical surgical strategies still dominate the care for acute and chronic pathology of the ascending aorta and the proximal arch region, new endovascular concepts are emerging and are likely to evolve as primary treatment strategies for descending aortic pathology in suitable patients.
