The world's rare disease "five-linked disease" 9-year-old child successfully completed surgery in Harbin through 3D printing technology

Release date: 2016-01-18

On January 6th, Vice-President Li Huaining of Harbin Children's Hospital led the team of the Xinwai team to cooperate with the team of Professor Jiang Shulin of the Department of Cardiovascular Surgery of Harbin Medical University and the team of Professor Cui Jian of the Fourth Hospital of Harbin Medical University. With 3D printing technology, it lasted 7.5 hours. For a 9-year-old Cantrell hypothyroid disease in the world, he successfully completed 12 operations including right-handed single-atrial septal plasty, ventricular defect repair, and right ventricular outflow tract. On the 13th, the reporter saw the well-guarded girl in the intensive care unit of Harbin Children's Hospital. The girl was clear-headed and recovered well.

According to reports, this complex heart, chest and abdominal wall deformity can not accurately determine the specific shape of the deformity before surgery with conventional diagnostic methods. The surgical team used 3D printing technology to discuss the surgical plan several times before surgery, and deduced the surgical procedure on the printed 3D model to preview the surgical accident.

For this rare congenital malformation, most of the successful reports at home and abroad are infants, that is, less than 2 years old, the baby is relatively easy to rebuild due to rapid growth and regenerative ability. In this case, the child is 9 years old. For children, the chest wall, abdominal wall and surrounding bone tissue are fixed in position and grow relatively slowly, which makes it difficult for surgery reconstruction. On the other hand, the child's heart is complex and deformed, and its blood oxygen carrying capacity is reduced compared with normal children, and the body's resistance is poor. If artificial large-area materials are used to repair large-area defects, it is bound to increase the possibility of postoperative infection of the implant. These two traditional methods can not be used. After repeated discussion, the surgical team has taken a different approach and used the patient's own rectus abdominis muscle as a reconstruction material for the chest wall and abdominal wall defects. This kind of congenital malformation correction surgery done with one-time abdominal muscles at home and abroad No reports have been reported.
