I believe there are many people who already know a lot about aortic coarctation, but there are still many people who have aortic coarctation type a and don’t know what it means, so let’s go together to understand what exactly is aortic coarctation type a. 1, aortic coarctation refers to the aortic cavity blood from the aortic intima tear into the aortic intima, is the aortic intima further to a greater degree of tearing, the formation of the aortic wall of the true and false separation of the two cavities is called aortic coarctation, type a aortic coarctation is mainly refers to the intima rupture is located in the ascending aorta. 2, the extension will go beyond the aortic arch, the distal tear up to the abdominal aorta and even the iliac artery, very dangerous, and its mortality rate is very high, if not timely treatment, within 24 hours to two weeks, its mortality rate can reach 70%, if once diagnosed should go to active surgery or interventional treatment. The disease of aortic coarctation type a is very dangerous, I believe that we can try to protect their own bodies, we may be an inadvertent action will lead to a lot of pressure in the body, we have to go to a regular habit of life, for our body organs to reduce the pressure, reduce the disease.
