As a pediatric cardiac surgeon for more than 20 years, I would like to share my views and hope that they will be helpful to parents of children with precocious heart disease. I. Choose minimally invasive treatment Sternal deformity occurs after surgery for precordial disease, mainly related to the median sternotomy. After the suture of median sternotomy, some younger infants and children, especially those with severe pneumonia or critical precocious heart disease, have softer sternum, and often struggle to breathe after evacuating the ventilator after surgery, and the lower part of the sternum is prone to depression and later easy to form funnel chest; while most children with median sternotomy of precocious heart disease are more prone to form sternal healing bulge, i.e. chicken chest. In order to prevent the occurrence of postoperative sternal deformity in precordial disease, for some common precordial diseases, it is better to choose side incision or small median incision for partial sternotomy and surgical minimally invasive blocking treatment, which can completely avoid the occurrence of corpus cavernosum or funnel chest. However, for choosing lateral incision, small median incision or surgical minimally invasive treatment, the operator needs to have rich experience and skills; in addition, the age of the child should be better than 6 months; complex precordial disease can choose small median incision, and it is better to avoid lateral incision in order to reduce the risk of surgery to the minimum. Second, postoperative prevention For children who need to perform a median incision all sternotomy, most children will have augmentation during the healing process of the sternum in the short term, but generally after six months the augmented sternum will disappear naturally, individual children sternal augmentation persists, that is, the formation of chicken chest, for this reason, in order to prevent the occurrence of postoperative chicken chest, one requires the doctor to suture the incised sternum after cardiac surgery is accurate alignment fixed, the second is the recent postoperative Use chest band or chicken chest instrument, for those who have formed chicken chest, you can choose orthopedic small splint to properly press the augmentation, fixed with chest band, after a period of time, the sternum will become flat. Although the incidence of postoperative funnel chest is extremely low, it is very difficult to prevent postoperative funnel chest. I have used various methods to suture the sternum in some children with severe pneumonia predilection in the postoperative period, but the results are not satisfactory. For some children with severe sternal depression, they need to be surgically corrected again later.
