Patient: The child is now 8.5 months old and was born with a grape-like birthmark on his left leg, which is now slightly enlarged. He was seen by you on September 7, but due to the short period of time, there are some situations that I would like to get further help from you. 1. If a bandage is used to counteract the abnormal development of the left leg, how long should it be tied? 2. We have read about the dangers of KT and are very worried that our child will have a large abnormal left leg or a long and short leg trek. Ultrasound findings: soft tissue enhancement and thickening in the left calf and medial left foot, with uneven echogenicity, about 12 MM at the thicker area. CDFI: sparse short strips of blood flow signal seen in the left calf and medial left foot. Zhang Jing, Department of Interventional Therapy, Guangzhou Children’s Hospital: It depends on the development of the disease, some cases need to be used for life, generally children can customize elastic stockings when they grow up, which is more convenient to use; at present, we can review while observing, if there is rapid development or other abnormalities appear we will give some targeted treatment to control the progress of the lesion; if necessary, we will do the above treatment. Patient: Thank you Dr. Zhang, but I still have the following confusion and would like to ask for your help: 1. What is this disease all about and why is it so difficult to cure? 2, in fact, the most worried is afraid that this disease will make the baby appear long and short legs, resulting in lameness, he is so cute, really can not bear to see him suffer this kind of crime. Is there an effective way to stop this phenomenon from occurring? 3. You asked us to see you again on October 12 for a follow-up consultation, is that the time to make targeted treatment measures according to BB’s condition? 4. It is true that BB’s left calf is not as dark as before after the bandage is put on now, but after loosening it for a while, it returns to its original shape. We are very anxious about this. The mood has not been able to calm down. Guangzhou Children’s Hospital interventional therapy department Zhang Jing: is a congenital malformation formed by abnormal embryonic development, difficult to completely cure; leg growth is generally related to arteriovenous fistula, can do interventional surgery, most can be controlled to a certain extent, generally will not have a major impact on the child; review and then decide; is so.
