Pulmonary stenosis surgery does not necessarily need to open the chest, according to the patient’s specific situation to choose the appropriate surgical methods, interventional surgery does not need to open the chest. 1. Interventional surgery: If the pulmonary artery stenosis is simple, you can choose interventional surgery, the surgery is generally percutaneous intervention balloon expansion, through the femoral vein of the thigh, for the balloon expansion of the pulmonary artery, the surgical incision is only femoral vein, but due to the lack of open-chest visualization of the conditions, the emergence of accidents may be difficult to rescue in a timely manner. 2. Open-heart surgery: If pulmonary stenosis is serious and combined with other intracardiac malformations, open-heart surgery is required. The success rate of the surgery is high and the curative effect is accurate, but the postoperative recovery of open-heart surgery is slow and a large incision in the middle of the sternum is left behind. If pulmonary stenosis occurs, it is important to seek medical attention as soon as possible to avoid adverse complications.
