With the rapid development of modern medicine, surgical interventional occlusion technology (also called hybrid technology, composite technology) combines open-chest direct cardiac surgery and medical interventional surgical methods to perform interventional treatment through a tiny surgical incision, giving full play to the respective advantages of the first two methods, with no extracorporeal circulation, small trauma, fast recovery, no radiation damage, no contrast damage, no peripheral vascular injury and other risks. At present, surgical interventional occlusion technology has been widely carried out worldwide. Since the Third Affiliated Hospital of Zhengzhou University started the surgical occlusion of precardiac disease two years ago, the Center has successfully applied ultrasound-guided surgical occlusion to treat dozens of children with ventricular and atrial defects, with a 100% success rate and no complications and good results. Our cardiac surgery department can perform both direct cardiac surgery and surgical intervention. These two treatment methods have their own advantages and disadvantages. Intracardiac direct vision surgery has a long history and exact effect, which has been tested for a long time and has good treatment effect and long-term results, while transthoracic surgical occlusion is less traumatic, without the influence of radiation and contrast agent and without peripheral vascular loss, but as a new technology carried out relatively late in China, the recent effect is good and the long-term effect needs further follow-up. These two techniques complement each other and are suitable for different patients, and we can take different treatment plans according to the patient’s condition. The surgical interventional occlusion technique is mainly suitable for transthoracic occlusion of atrial septal defect, ventricular septal defect and patent ductus arteriosus, pulmonary valve stenosis expansion and stent placement, etc. Its outstanding features are safety and minimally invasive, which are reflected in the following aspects: there is no age and weight limit, early detection and early treatment can be achieved; the skin incision is tiny, about 2cm long; no extracorporeal circulation is needed, less blood loss, no intraoperative The two methods can be switched at any time, and once the blockage is unsuccessful, it can be changed to open-heart direct vision surgery at any time; no radiation, no contrast damage; no damage to peripheral blood vessels.
