1. Blood pressure control Shanghai Changhai Hospital, Department of Vascular Surgery, Lu Qing-sheng Adequate blood pressure control is of great significance in the rescue of aortic coarctation. Lowering blood pressure can reduce the irritation of blood flow to the vessel wall and prevent further separation of the vessel wall. Generally speaking, the threat to patient’s life from aortic coarctation is not limited to the coarctation itself, but is also closely related to the hematoma in the coarctation. If the hematoma progresses, it can lead to severe hypertension, cardiac tamponade, aortic rupture hemorrhage, and other serious life-threatening conditions. Therefore, patients with aortic coarctation should have strict control of blood pressure and heart rate. It has been shown that patients with poorly controlled blood pressure are 10 times more likely to have late rupture of aortic coarctation than those with good blood pressure control. 2. Traditional surgical treatment Since the 1950s, traditional vascular surgery techniques have made great progress, and doctors have saved many patients’ lives by applying artificial vessels to replace the diseased aorta. However, there are many problems with traditional surgery: (1) the incision is 40-100 cm long to better reveal the lesion; (2) the surgery is complicated, with long anesthesia time and the need for large amounts of blood transfusion; (3) the blood vessel must be blocked to perform vascular anastomosis, which inevitably affects the blood supply to the organ distal to the blocked vessel, easily leading to complications such as renal failure, liver failure and paraplegia; (4) the surgery is traumatic, risky, and requires high technical In the 1990s, the emergence of endoluminal vascular surgery technology made the minimally invasive treatment of aortic coarctation possible. In recent years, with the continuous progress of endoluminal vascular surgery technology and equipment, the diagnosis and treatment mode of thoracic and abdominal aortic coarctation has shifted from traditional open surgery to endoluminal minimally invasive treatment. For treatment, the surgeon simply makes a small incision of about 3 cm at the root of the patient’s thigh, and under X-ray fluoroscopy, a stented artificial vessel constricted in a catheter is introduced into the aorta via the femoral artery (Figure 1), and when the artificial vessel reaches the lesion site, it is released from the catheter and the memory alloy stent is opened (Figure 2), anchoring the artificial vessel to the normal arteries at the ends of the diseased aorta (also known as “anchorage zone”), blood flow is then passed through the stent lumen and the false lumen is gradually shrunk (Figure 3). Figure 1 Introduction of artificial vessel with stent Figure 2 Artificial vessel stent is released to seal the main fissure Figure 3 Rupture is closed and the false lumen is shrunken Compared with traditional surgery, minimally invasive endoluminal isolation is less invasive, patients can eat the same night after surgery and can get out of bed the next day, and the incidence of surgical complications and mortality are significantly reduced, and many patients who are elderly and combined with multiple chronic diseases and cannot tolerate traditional surgery are given a cure The chance of cure. This is what we often say – the most minimally invasive technique to cure the most dangerous diseases.
