When a tear occurs in the innermost layer of the aortic wall blood is then channeled into the wall of the aorta separating the layers of tissues. Aortic dissection is the prototype and most common form of acute aortic syndromes and a type of arterial dissectionIt occurs when blood enters the medial layer of the aortic wall through a tear or penetrating ulcer in the intima and tracks longitudinally along with the media forming a second blood-filled channel false lumen within the vessel wall. As succinate triggers inflammatory changes in macrophages we investigated the significance of succinate in the pathogenesis of AAD and its clinical relevance.
