Open artery catheter ligation and suture

1. After the arterial catheter is diagnosed, surgery is performed at any age in principle, but the best surgical age is 5 to 7 years old (that is, preschool age). Before the age of 5 years, if the condition is serious and it is difficult to sustain life without surgery, early surgical treatment should also be performed. If the patient has heart failure, it is best to perform surgery after the heart failure is stable for 3 months; if the heart failure cannot be controlled, it should be surgically treated under the supervision of drug therapy. If there is bacterial endocarditis, a large dose of intravenous antibiotics should be applied, and the operation should be performed after the endocarditis is controlled for 3 months. If endocarditis cannot be controlled, rescue surgery should be performed at the same time as high-dose antibiotics. 2. If the catheter is slender, it is usually used for ligation. When the diameter of the catheter is greater than 1cm, and the length of the catheter is less than 0.5cm, the ligation may break the catheter, and the suture should be selected. For patients with obvious pulmonary hypertension, severe suture is generally used; recanalization is easy to occur after ligation.
