Еndovascular treatment of traumatic aortic injury

Acute aortic syndromes represent a group of life-threatening conditions characterized by disruption of the integrity of the aortic wall and a high risk of rupture and fatal outcome. These include aortic dissection, intramural hematoma, and penetrating atherosclerotic ulcer, which share similar pathophysiological mechanisms. Traumatic aortic injury represents a distinct clinical entity resulting from high-energy blunt chest trauma and is associated with signifi cant early mortality. Blunt traumatic injury of the thoracic aorta most commonly occurs as a result of sudden deceleration forces during road traffi c accidents or falls from height. The most frequently affected segment is the aortic isthmus, due to the anatomical and biomechanical characteristics of the transition between the mobile aortic arch and the fi xed descending thoracic aorta. A substantial proportion of patients die at the scene of the incident, and among those who survive the fi rst hours, the risk of subsequent rupture remains high. Computed tomography angiography is the method of choice for diagnosis and therapeutic planning in traumatic aorti
