Abdominal aortic coarctation is a separation of an artery from the abdominal aorta due to degenerative disease or external forces that cause rupture of the intima, and blood leaks through the rupture in the intima into the middle layer of the aortic wall. After the formation of an entrapment in the abdominal aorta, it may extend upward and downward along the longitudinal axis causing aneurysmal dilatation. The resulting hematoma compresses the corresponding arterial branches and may lead to symptoms of organ ischemia such as acute ischemic nephrosis and splenic necrosis. Abdominal aortic coarctation carries a great risk of rupture and when it occurs, the patient has sudden severe tearing pain. In severe cases, the rupture of the dissection can be fatal due to massive bleeding, resulting in acute heart failure or severe shock. The main methods to confirm the diagnosis of abdominal aortic coarctation are CTA and MRI, and the application of abdominal ultrasound also has some diagnostic value. The risk of abdominal aortic coarctation is very high, and it is recommended that patients go to the hospital in time according to the symptoms, so as not to delay the condition and cause serious consequences.
