heart stent surgery

Cardiac stent surgery is a new technology for improving myocardial insufficiency and cardiac artery occlusion caused by coronary heart disease in the last 20 years. Simply put, the process of cardiac stent surgery is to puncture the blood vessels, make the catheter advance in the blood vessels, reach the opening of the coronary artery, use a special delivery system to transport the stent to the site where it needs to be placed, place and withdraw the catheter, and end the operation. . The patient underwent surgery under local anesthesia. He usually gets out of bed after 24 hours of puncture, and is usually discharged three days after surgery. Treating diseases: coronary atherosclerotic heart disease Indication Acute myocardial infarction Within 6 hours after the occurrence of myocardial infarction, the interventional treatment should be carried out as soon as possible to the conditional hospital, and the blood vessels that have been occluded can be quickly opened. The effect of recovery of cardiac function is better than that of thrombolysis and drug treatment. Unstable angina Because of the possibility of evolving into an acute myocardial infarction, a cardiac stent is suitable. Labor angina The patient walks a little further and may experience symptoms such as chest pain and chest tightness. Sitting quietly or resting for a while, the symptoms will ease. Fallot tetralogy In patients with abnormal anatomy of the coronary arteries, placement of the percutaneous right ventricular outflow tract into the cardiac stent is less risky than surgery alone. Complex congenital heart disease Complex congenital heart disease such as severe pulmonary stenosis or pulmonary atresia, suitable for placement of stents in the percutaneous catheter. Contraindications After coronary angiography, the occlusion of the stenosis is determined. Cardiologists generally believe that more than 75% of patients with occlusion often have myocardial infarction, and those aged 30-65 years old can't stand the body. Surgical procedure 1. During treatment, the doctor first extends a very thin catheter through the blood vessel to the narrowed artery. 2. Then, use a filling rubber balloon to open the narrow area. 3. Finally, the artery stent is held in the narrowed artery that has been dilated to prevent it from retracting. 4. After exiting all the catheters, the arterial stent remains in the narrowed artery that has been dilated.
