Question
The child’s hands, feet, and lips have turned purple, and their hands appear blackish. They have undergone CT scans, echocardiograms, and blood tests, all of which have come back normal.
Answer
It may be congenital heart disease. Treatment requires surgical intervention, involving ligation and excision combined with suturing. Postoperative care is necessary. If the condition worsens rapidly or there are frequent respiratory tract infections, symptomatic treatment should be actively pursued. Children have many causes of endocrine diseases. Immediate treatment should be sought after diagnosis, along with stress reduction and good hygiene habits. Parents should avoid letting their children picky eat or have a biased diet and maintain a reasonable diet.
