Aortic coarctation that gives doctors the creeps

  A very dangerous complication of hypertension is aortic coarctation! Once it occurs, the chances of successful resuscitation are extremely low. Doctors encounter such complications and sometimes sigh helplessly: nasty entrapment!  1. How is aortic coarctation formed?  Let’s start with the structure of the aorta. The large blood vessel emanating from the heart is called the aorta, which is divided into the thoracic aorta and abdominal aorta according to the different stages along the aorta, and then continues with a number of descendant bifurcations up to the microcirculatory capillaries to meet the blood supply of the whole body. The aortic vasculature consists of three inner and three outer layers, namely the inner, middle and outer layers (called in medical terminology the inner, middle and outer membranes), which are closely fitted together to form a resilient to carry the transported blood.  In a healthy state, the three layers cannot be split apart, and when some reason causes a gap to open between the inner and middle layers of the artery, a sinister aortic coarctation is formed. The formation of this gap is related to the usual day-to-day hardening, damage, plaque, and calcification formation of the local blood vessels until finally a broken open gap is formed under strong pressure.  Once the aortic coarctation gap is formed, this gap will “break” under the strong blood pressure and rapidly expand the inner middle layer of the aorta to gradually peel off and expand (as shown above), up to the heart and down to the tail of the abdominal aorta, leading to a series of manifestations mainly tear-like pain, including shock and rapid death.  2.How to prevent aortic coarctation in hypertension?  There are many common causes of aortic coarctation, including some precordial diseases such as Marfan syndrome, idiopathic degenerative changes in the aortic mesentery, aortic atherosclerosis, and aortic inflammatory. Due to the increasing popularity of eugenics prenatal checkups, precardiac disease has become rare, so the most common cause of aortic coarctation is hypertension (including primary hypertension and secondary hypertension), and almost all patients with aortic coarctation are hypertensive patients with poor blood pressure control. In other words, every one of the 300 million patients with hypertension in China must achieve blood pressure control to normal range when it comes to antihypertensive treatment.  Pregnancy is another factor that causes aortic coarctation and may be related to altered hemodynamics during pregnancy. If pregnancy is then combined with hypertension, known as hypertension, it should be given high priority and the decision to advise the patient to terminate the pregnancy should be made in appropriate cases depending on how well the blood pressure is controlled.  Therefore, the main measure to prevent aortic coarctation in hypertensive patients is to always control the blood pressure to the level required by the doctor (medically called attainment); if combined with hyperlipidemia, diabetes mellitus and other comprehensive vascular risk factors, the patient should pay enough attention.
