Peng Peng (a pseudonym), a 3-and-a-half-year-old boy repeatedly infected with pneumonia, was diagnosed with congenital heart disease with patent ductus arteriosus and underwent "percutaneous patent ductus arteriosus closure" intervention in the pediatrics of the East Hospital of the people's Hospital of Wuhan University (Hubei Provincial People's Hospital).
Because Peng Peng's arterial catheter is a long funnel-shaped one with the narrowest inner diameter less than 2mm, it is difficult to complete the traditional operation. Professor He Bing, vice president of the East Hospital and director of Pediatrics of the people's Hospital of Wuhan University, and Dr. Tuohu team from the Department of cardiovascular diseases achieved "reverse arrest" through minimally invasive intervention, established a track, successfully blocked the arterial catheter, and Peng Peng recovered well after operation, Discharged smoothly.
Professor He Bing introduced that the arterial catheter (PDA) was originally the normal blood flow channel between the pulmonary artery and aorta in the fetal period. After birth, the baby starts spontaneous breathing of the lungs and the arterial catheter closes automatically within 24 hours. If the channel cannot be closed continuously, patent ductus arteriosus is a congenital heart disease. This is a common congenital cardiovascular malformation, accounting for 12% ~ 15% of the total number of congenital heart diseases. The disease can lead to children's growth retardation, decreased activity tolerance, repeated respiratory tract infection, heart enlargement, increased pulmonary circulation pressure and resistance, heart failure and other symptoms. Therefore, the disease needs early detection and treatment. The patient can be cured by blocking the patent ductus arteriosus and interrupting its blood flow in a minimally invasive way.
This time, the pediatric cardiovascular team of the East Hospital of the people's Hospital of Wuhan University developed a special "retrograde capture" scheme for Peng Peng, which is to introduce the super sliding guide wire through the arterial end, let the catheter as thin as a hairspring pass through the small heart, and pull the guide wire into the artery and establish the arteriovenous track after capturing the guide wire through the catcher at the venous end. With the deployment of the occluder, it can be seen on the computer display that the occluder was successfully implanted into the patent ductus arteriosus of children. Postoperative angiography showed that the occluder was in good position and no residual shunt was found. After Peng Peng was returned to the ward, all vital signs were stable, and he could go to the ground the next day after operation.
"Generally speaking, cardiac interventional therapy is the treatment of congenital heart disease without thoracotomy. Compared with traditional surgery, interventional therapy has the advantages of less trauma, shorter operation time, faster postoperative recovery and fewer complications. Generally, it can be discharged two days after operation." Dr. Tuo Hu said that at present, transcatheter closure of patent ductus arteriosus has become the main treatment for patent ductus arteriosus.
