Aortic coarctation is a very aggressive type of disease of the great vessels, which is caused by long-term hypertension and unhealthy blood vessels, resulting in the formation of a rupture in the intima and mesima of the aorta, through which blood enters, creating a situation of two chambers, real and false. In the diagnosis of aortic coarctation, it is mainly determined by CTA of the aorta. The contrast of the CTA contrast agent reveals the true lumen as well as the false lumen, and clarifies the typology as well as the degree of aortic coarctation. In terms of treatment, type A aortic coarctation requires artificial vessel replacement plus implantation of a descending aortic stent, while type B aortic coarctation can be treated simply with implantation of a descending aortic overmolded stent. After the surgery, cardiotonic, diuretic, antihypertensive, and myocardial nutrition treatments are also required for a rapid recovery of the patient.
