What is aortic coarctation? The aorta is composed of three layers of structures called the intima, mesentery and epia. In so-called aortic coarctation, blood flow in the lumen of the aorta enters the mesentery through the tear in the endothelium and splits the vessel wall into true and false lumens, which become aortic coarctation. The false lumen continues to increase in size and can form a coarctation aneurysm. Aortic coarctation has a rapid and extensive destructive onset and can cause aortic rupture and ischemia of organs and limbs leading to death in the acute phase, while in the chronic phase, the aortic coarctation can gradually expand to form a coarctation aneurysm. As the diameter of the aneurysm increases, the patient’s entrapped aneurysm will eventually rupture leading to death. Clinical manifestations of aortic coarctation 1. severe pain like tearing or cutting in the chest and back and abdomen; 2. patients often have a sharp increase in blood pressure; 3. ischemic manifestations of organs and limbs; 4. hemiplegia, paraplegia, confusion, coma, intestinal obstruction, pain in the extremities, weakness, renal failure, aneurysm rupture may appear as shock, pericardial tamponade, blood in the chest, vomiting, hemoptysis, and difficulty in inspiration. Treatment of aortic coarctation Drug treatment: Hypotension, analgesia, sedation. Traditional surgery: open chest, open abdomen, replacement of the diseased aorta with artificial blood vessels, which is difficult and complicated to operate, with high surgical complications and mortality. Endovascular isolation
Minimally invasive interventional method, only a small inguinal incision is needed to implant the overlapping stent into the lumen of the diseased vessel to isolate the rupture. The method is fast and effective, with little patient pain and complications, and is a new treatment method that has been increasingly performed in recent years.
