The human aorta is composed of an intima, a middle elastic layer, and an outer membrane, and under normal circumstances these three layers are closely fitted together. Aortic coarctation refers to the destruction of the aortic wall by certain pathological factors, and the high speed and high pressure arterial blood flow separates its inner and outer membranes, thus forming a pseudo-lumen of the coarctation and causing the outer membrane of the thoracic aorta near the rupture to expand, and blood flows in the pseudo-lumen and squeezes the true lumen, so it is also called aortic coarctation hematoma, or aortic coarctation for short. When aortic entrapment ruptures, blood flows rapidly into the pericardial cavity or the left pleural cavity, which can rapidly lead to death. The disease has a rapid onset and very high mortality rate, and is extremely dangerous, making it the number one human disease killer. Clamp tears can start anywhere in the aorta, but the most common sites are in the proximal part of the ascending aorta, within 5 cm of the aortic valve, and below the opening of the left subclavian artery in the thoracic segment of the descending aorta. Therefore, once acute thoracic back tear-like pain occurs, a high degree of vigilance and suspicion for aortic coarctation disease is warranted. Patients should immediately undergo the following examinations and diagnoses: 1. A plain chest radiograph can provide a clue to the diagnosis. For patients with acute thoracic back tear-like pain with hypertension, if a widened upper mediastinal shadow or a widened aortic shadow is found in the chest radiograph, further examinations such as CTA must be performed to clarify the diagnosis. 2. Aortic CTA is the most commonly used preoperative imaging assessment method, with a sensitivity of 90 CTA tomography can be observed to divide the aorta into true and false chambers, and the reconstructed image can provide two-dimensional and three-dimensional images of the whole aorta. Its main disadvantage is that contrast agent has to be injected and corresponding complications may occur, and artifacts produced by aortic pulsation can interfere with the image and diagnosis. After a clear diagnosis of aortic coarctation disease, the following treatments may be chosen depending on the patient’s specific situation: conservative treatment, minimally invasive interventional treatment and traditional major surgical treatment. Minimally invasive endoluminal interventions can minimize the invasiveness of the procedure and have minimal impact on the patient’s respiratory and circulatory vital signs, which greatly increases the safety of the procedure and the survival rate of the patient.
