[Acute and chronic pathologies of the thoracic aorta: From diagnosis to treatment].

Aortic pathologies benefit from imaging innovation and interventional radiology developments in order to improve patient management. At the early phase, vital risk should be considered. Whole body CT scan evaluate the complete aorta and its branches to assess the pathology and to choose the best approach between surgery or interventional radiology (fenestration, stentgraft, peripheral stenting). Algorithms, based on the understanding of the complications mechanisms and evolutive risk, modified the management specifically for aortic dissection. At chronic phase, GPs and angiologists should follow their patients in order to detect aortic complications and to treat cardiovascular risk factors. MRA is well indicated if possible.
