The common typing methods for aortic coarctation are: 1. Debakey typing: depending on the extent of involvement of the rupture and the coarctation, for example, type I endothelial rupture is usually located in the ascending aorta, and the coarctation tear can involve the ascending aorta, aortic arch, descending aorta, and abdominal aorta; type II endothelial rupture is in the ascending aorta, but the scope of the coarctation is limited to the ascending aorta; type III rupture is located in the descending arch or abdominal aorta, and the coarctation is located in the descending arch, thoracic aorta, and abdominal aorta; 2. Stanford typing: coarctation involving the ascending aorta is type A coarctation, and coarctation involving the descending arch and abdominal aorta is type B coarctation.
