In July 2011, the Department of Cardiothoracic Surgery at Gulou Hospital in Jiangsu Province held a special patients’ meeting. The 40 patients had all suffered from aortic coarctation aneurysms (also known as aortic coarctation) and had successfully recovered. Experts say the experiences of these patients show that good blood pressure control can prevent 90 percent of aortic coarctations. An aortic coarctation aneurysm, also known as an aortic entrapment, is not really a tumor. Surgical treatment is commonly understood as the removal of the aneurysmal portion of the artery and its replacement with an appropriately sized artificial vessel. Zhang Chun buckle, 46, had a history of hypertension for many years, but had not been paying attention to controlling his blood pressure. On June 11 of this year, he suddenly felt a sharp pain in his chest and a rush of blood upward. Transferred to Gulou Hospital, just opened the chest blood vessels burst, blood sprayed the chief of the hospital’s cardiothoracic surgery director Wang Dongjin face. Thanks to Wang Dongjin a few seconds to find the burst blood vessel and timely stop bleeding, and then a little later the patient will be dead. Wang Dongjin said that the most typical symptom of aortic coarctation is severe chest pain, 90% of patients first symptoms for the sudden onset, persistent, progressive aggravation of severe chest pain, stabbing, tearing-like or knife-like pain, the patient often can not stand, at this time dripping with sweat, containing nitroglycerin is not effective. And once the onset of the disease, most of them will die within a week. Xu Biao, director of the Department of Cardiology at Gulou Hospital, said that aortic coarctation mainly attacks two types of people, one is congenital vascular dysplasia, such as patients with Marfan’s syndrome; the other is hypertensive patients, accounting for 90 percent. “Controlling hypertension will prevent 90 percent of aortic coarctations.” Xu Biao said. According to the report, aortic coarctation surgery is considered the most complex and risky surgery in cardiothoracic surgery, with a high mortality rate and a low success rate, and no surgeon can guarantee 100 percent success. Surgery has a 50% success rate, without surgery the mortality rate is 100%. Not only that, since the patient’s blood vessel can rupture at any time and will die within minutes as soon as it ruptures, the patient should be operated as soon as it is detected and should not hesitate. In the early stages of the disease, the operative mortality rate was about 20%D30%, and the long-term survival rate was very low. However, the operative mortality rate has now decreased to about 5% to 10%, and the long-term survival rate has also improved significantly. Gulou Hospital has treated 211 patients of this type since 2002, and the success rate and long-term survival rate have reached international standards.
