The reason why the 2-year-old boy suddenly turns black and blue is that

Huihui, a 2-year-old, is lively and lovely. He should have been loved by thousands of people. However, no children would like to play with him. Even adults are deliberately or unintentionally away from him. Huihui had a disease that made Huihui look like an endangered patient.

This kind of disease is pulmonary arteriovenous fistula, which is a very rare lung disease. It will cause long-term hypoxia and high mortality without treatment. Recently, a hospital in Shenzhen made precise and minimally invasive interventional treatment for Huihui, which not only saved his life, but also exempted Huihui from suffering from discrimination due to his dark skin.

Hospital for children with unknown etiology

More than a month ago, Huihui's face and lips suddenly began to turn blue and purple and black. "Congenital heart disease", "food poisoning", "infectious disease" and other conjectures and doubts filled Huihui's whole family. However, the cause of the disease is still unclear after he went to seek medical treatment. Not only is the family's economic burden more and more heavy, but also people around him are deliberately alienated due to Huihui's illness.

Until half a month ago, Huihui's parents took him to the hospital. After the doctor received him, his first impression was "difficult and miscellaneous diseases", because Huihui's symptoms looked like "congenital heart disease", but he couldn't find any bad performance of heart function. For further diagnosis and treatment, on November 4, Huihui entered the cardiovascular department. The cardiovascular physician immediately reported Huihui's related condition to the superior physician. The chief physician of the Department attached great importance to it and organized the diagnosis and treatment work quickly. After preliminary examination, congenital heart disease, food poisoning and infectious diseases were basically excluded. Then, the discussion in the Department was immediately carried out. After careful analysis of the condition, the possibility of pulmonary arteriovenous fistula was considered to be the greatest.

Experts completed bedside echocardiography and contrast-enhanced echocardiography, the results clearly suggested that 'pulmonary artery fistula' may be possible, and then contacted the radiology department to quickly improve the CT + enhancement of the heart, which was consistent with the clinical report, and finally 'pulmonary arteriovenous fistula' was confirmed.

According to doctors, pulmonary arteriovenous fistula is a rare pulmonary disease, which is the abnormal communication between pulmonary artery and pulmonary vein. The incidence of this disease in women is about twice that in men, and the diagnosis rate in infancy or childhood is only 10%. With the growth of age, the disease's apparent rate is increasing. The natural outcome of this disease is not good, and the mortality rate of untreated patients is 11%.

Improvement of patients' condition after minimally invasive surgery

After the diagnosis was made clear, the chief physician organized the discussion in the department again, discussed the treatment plan, and agreed that minimally invasive interventional surgery was the first treatment plan. On November 9, after 7 hours of hard work, the operation was successfully completed.

After the operation, Huihui's blood oxygen saturation rose from 70% to 95% before the operation. Finally, Huihui got rid of the skin cyanosis and blackness caused by long-term hypoxia. It can be seen that Huihui's complexion and lips changed from cyanosis and blackness before the operation to pink, white and tender. A 2-year-old child's innocence and liveliness reappeared on Huihui's face.
