[Aortic dissection at the acute phase].

ACUTE AORTIC DISSECTION Acute aortic dissection is the most common and dramatic of aortic emergencies. The many complications that it generates, such as rupture or malperfusion, make it a complex pathology to be managed in the context of an emergency, which requires many medical and surgical skills. Its medical management is based on the control of arterial pressure, and its surgical treatment on the replacement of the ascending aorta when damaged, or the endovascular repair of the descending thoracic aorta by aortic stentgraft. The clinical and radiological features of its prevention in the general population are unfortunately still little recognized.
