The Xiamen Heart and Cardiac Surgery team performs aortic dissection surgery.
The reporter learned from the First Affiliated Hospital of Xiamen University, the Cardiovascular Hospital Affiliated to Xiamen University (hereinafter referred to as Xiamen Heart) and other hospitals that the temperature dropped sharply some time ago, and the number of patients with aortic dissection increased significantly. Cardiac surgeons caution that controlling blood pressure is key to preventing aortic dissection.
Phenomenon. The temperature drops sharply and the number of patients with aortic dissection increases.
Grandma Liu, who is in her 80s, suffers from arteriosclerosis and high blood pressure, and a few days ago, because of chest pain and syncope, she was referred to the Department of Cardiac Surgery of the First Affiliated Hospital of Xiamen University and was diagnosed with type A aortic dissection. The cardiac surgery team performed emergency surgery on him, and after experiencing respiratory failure, kidney failure and other difficulties, the old man was successfully discharged from the hospital two days later.
The reporter learned from the Department of Cardiac Surgery of the First Hospital that in the past three days, the department has admitted 4 patients with aortic dissection, "According to my clinical experience, after the sudden drop in temperature, the number of patients tends to increase, and it is currently the high incidence period of the disease." Kuang Feng, deputy chief physician of the cardiac surgery department of the First Hospital, said.
This is also the case with Xiaxin. From January 25th to 30th, the hospital admitted 37 patients with aortic dissection, of which the peak period was from 9 a.m. to 4 a.m. the next day on January 25, and the medical staff fought for 19 hours in a row to successfully "defuse" 6 patients with type A aortic dissection who encountered danger, the oldest patient was 73 years old, and the youngest was 33 years old
Analyse. Sudden onset of type A aortic dissection is the most dangerous.
Peng Hua, head of the second department of cardiac surgery in Xiaxin, said that the aorta is a large artery that extends from the heart to supply blood to the whole body, and it is under great pressure from the blood just pumped out of the heart. Aortic dissection refers to the blood in the aortic lumen entering the aortic intima from the aortic intimal tear, and gradually peeling off the intima and the media, forming a true and false cavity of the blood vessel. Once the dissection ruptures, a large amount of blood will suddenly rush to the heart, leading to cardiac arrest, which is a very dangerous cardiac critical illness.
Aortic dissection tends to occur suddenly, with acute severe chest pain that cannot be relieved as the main symptom. Depending on the location of the aorta tear, patients often also experience symptoms of multiple systems, such as abdominal pain, lower limb pain, purple toes, heart failure, sweating all over the body, headache, syncope, nausea, vomiting, dyspnea, etc. In this case, patients may develop hypotension due to large amounts of blood flowing to the false lumen and tears in the corresponding blood vessels in the extremities or due to massive cardiac fluid tamponade. Kuang Feng said.
Peng Hua said that aortic dissection is mainly divided into two types: A and B, and compared with type B, type A aortic dissection is more dangerous, with a very high mortality and disability rate. Acute type A aortic dissection without ** has a mortality rate of up to 50% within 48 hours and an increase of 1% every 1 hour, so it is called a "vascular bomb".
Kuang Feng explained that type A aortic dissection affects the ascending aorta, which is closer to the heart and carries a higher risk of rupture. Type B aortic dissection affects only the descending aorta and can be performed by medical or stent surgery in most patients**.
Let's popularize science. Aortic dissection.
Aortic dissection refers to the blood in the aortic lumen entering the aortic media from the aortic intima tear, separating the media, and expanding along the long axis of the aorta to form a state of true and false lumen separation of the aortic wall. The disease is rare, with an incidence of 1 in 100,000 to 1 in 200,000 per year, with a peak age of 50 to 70 years and a male-female ratio of about 2 3 to 1. 65% and 70% die of cardiac tamponade and arrhythmia in the acute stage, so early diagnosis and ** are very necessary.
Most patients have sudden onset chest and back pain, type A is more common in the anterior chest and interscapular area, and type B is more common in the back and abdomen. The pain is severe and unbearable, peaking immediately after the onset of the disease, in the form of a knife or tear. In a small number of patients with a slow onset, pain may be insignificant.
