Aortic coarctation refers to the passage of blood from the aortic lumen through an endothelial rupture into the middle layer of the aortic wall and tearing the middle layer of the aortic wall to form a false lumen. However, aortic coarctation can also occur in the absence of an endothelial rupture. The nomenclature of aortic coarctation is confusing, such as aortic coarctation, aortic coarctation formation, aortic coarctation dissection (separation) and coarctation aneurysm. In recent years, the term aorticdissection has been increasingly used by foreign scholars and has been recognized by many domestic scholars. Therefore, it is recommended that the term “aortic dissection” be used uniformly in China to facilitate standardization and communication. Aortic interstitial hematoma refers to the overflow of blood from the arterial lumen into the aortic wall without rupture of the outer membrane of the artery. Depending on the time of onset, aortic coarctation is divided into two categories: acute (14 days). There are two internationally accepted staging methods for aortic coarctation. DeBakey (DeBakey) typing: ① DeBakey type I, aortic coarctation starts from the ascending aorta (or aortic root) and involves most or all of the aorta; ② DeBakey type II, aortic coarctation involves only the ascending aorta; ③ DeBakey type III, aortic coarctation involves only the descending aorta (Ⅲa, involving only the thoracic descending aorta; Ⅲb, involving the thoracic and abdominal aorta ). Stanford typing, proposed by Daily and others in the 1970s, is divided into 2 types: ①Stanford type A, aortic coarctation involving the ascending aorta (including the aortic root); ②Stanford type B, aortic coarctation involving the descending aorta.
