The endothelial rupture of aortic coarctation is located next to the left subclavian artery in the aortic arch and is quite close to the opening of the left subclavian artery. If the cardiology department followed the conventional method to cover the rupture, the left subclavian artery might be blocked, and this artery is the source of blood supply to the left upper limb, which would definitely affect the function of the patient’s left upper limb and might even lead to paralysis of the left upper limb. In order to preserve the function of the patient’s left upper extremity, the cardiac medical and surgical team decided to perform a large vessel bypass first to ensure the blood supply of the left subclavian artery, and then to perform an interventional procedure, a combined medical and surgical technique known internationally as “hybrid” technique, which is characterized by less damage and greater benefit. The patient was able to get out of bed the day after surgery, with only about 5 cm long wounds under the clavicle and in the neck. The intervention was performed on the fourth postoperative day. Because of the bridge vessel, there was no need to worry about the blood flow in the subclavian artery, and the stent was placed with ease, covering the endothelial rupture of the aorta intact, and the patient was able to get out of bed the day after surgery. The patient was able to get out of bed on the same day after the surgery. After a review of the aortic CTA, it was confirmed that the stent with membrane was in good position and the artificial vessel between the left subclavian artery and the left common carotid artery was flowing smoothly, and the patient was discharged safely. In fact, many cases that were previously labeled as “sudden death” are today considered to be caused by aortic aneurysms. With the growing population of hypertensive patients, aortic aneurysms are a common occurrence. The main risk is rupture and hemorrhage, and about half of the patients die from rupture and hemorrhage in the acute phase of the disease. For this reason, a coarctation aneurysm is known as an “untimely bomb” in the human body. Aortic coarctation aneurysm is like a river bank in flood season, the inner bank has been torn open, the rushing river water into the inner and outer bank, and continue to violently impact the precarious outer bank, the consequences are unimaginable, the chance of successful rescue is very small, within a few minutes the patient may die from hemorrhagic shock. Proximal entrapment almost always requires arterial replacement surgery under surgical extracorporeal circulation, while distal entrapment can be treated by intervention i.e. retrograde upward through the lower limb artery to the aorta and implantation of a stent with membrane to close the endothelial rupture, the latter being less risky and less complicating than the former during the surgical period, but with a higher recurrence rate.
