Wang Meiling Zhuang Yufeng Shanghai Changhai Hospital, Department of Vascular Surgery Lu Qing Sheng Recently, the Department of Vascular Surgery welcomed the smallest patient in history, only ten months old, white, chubby, lively and cute, adults will tease him “giggling” into a ball, it seems that this innocent baby does not know that in their own body has buried a Health risks. The baby’s right leg was swollen and obviously thicker than the left leg. The mother and father, who were new parents, were very frightened by the situation and went to many famous children’s hospitals in China to seek medical help, which made the baby’s mother and father feel even more scared. The baby was referred to our vascular surgery department by the doctor’s recommendation, and on examination, Dr. Lu Qing Sheng, the deputy chief physician, found that the baby’s swollen right leg could be palpated at the groin with a significant fluctuation, accompanied by cat-like blood flow, and after further examination, it was determined to be a medically induced femoral arteriovenous fistula. It turned out that the baby had been treated at a local hospital for a cold three months earlier and had a femoral arteriovenous fistula caused by a right femoral vein puncture and blood draw. If left untreated, it can lead to a series of complications such as swollen and deformed legs and heart failure. Minimally invasive endovenous treatment is the first choice for the average patient with a femoral arteriovenous fistula. However, for this child, who is only 10 months old, the developmental reasons for minimally invasive endovenous treatment may have long-term sequelae, but because the child’s blood vessels are very thin and the traditional method is very difficult to perform, there are pros and cons to either option. The result can only be one, that is, to choose the most effective way, in order to make the long-term results better, Lu Qing Sheng, deputy director of the Department of Surgery, decided to challenge the traditional surgical approach. Before the operation, we organized a discussion with experts, invited Dr. Gan Lu from the Department of Pediatrics and Dr. Rui Bao from the Department of Anesthesiology, who is experienced in infant and child anesthesia, to evaluate the risks of intraoperative and perioperative care and to develop solutions. The operation was very successful. After the operation, the child was transferred to the pediatric department and was carefully treated and cared for by Dr. Gan Lu and nurse practitioner Guo Linfang. In a post-operative checkup, the parents of the child who accompanied him said excitedly: “We have been out for more than 3 months, we have been to all the major pediatric hospitals in the country, the doctors said to give up treatment, refused to take over, we are also discouraged, but fortunately we found here, Changhai Hospital saved my son’s life, we will let our son remember the benefactor forever! ” Professor Jing Zaiping, director of vascular surgery, said, “Deputy Director Lu Qing Sheng adopted the traditional surgical method very correctly, analyzed the problem very carefully, thoughtfully, and had a long-term vision. The success of this surgery was accomplished through the collaboration of multiple disciplines, which not only reflects the spirit of unity and cooperation of our Changhai people, but also shows the comprehensive strength of our Changhai Hospital. In recent years, with the increasing development of arteriovenous puncture vascular examination and interventional treatment in medical work, the incidence of medically induced femoral arteriovenous fistula is also gradually increasing, as doctors should strengthen basic skills training to avoid similar medical secondary disasters.”
