According to a survey data of WHO, the total number of people suffering from hemangioma in China is rising, but the effective cure rate of hemangioma disease is very low, which is not only because the current level of medical technology is not exquisite and the lack of hemangioma experts, but also because parents do not understand the symptoms of hemangioma and do not pay enough attention to the disease. Because some parents of children with hemangioma take the disease lightly, a large proportion of children with hemangioma cannot receive timely and effective treatment. So, how to determine whether a child is suffering from hemangioma? In fact, the most typical symptom of hemangioma that can be observed by the naked eye is redness or swelling with protrusion, but this is not enough to determine whether your child has hemangioma or not, and it is especially important for every parent to have the correct criteria for determining hemangioma. Many babies are born with hemangioma disease, and the initial manifestation is usually a small red spot or red bumps like mosquito bites, if parents think it is not a serious phenomenon, it will get better after a while. Therefore, parents should take their children to the hospital to find a doctor with rich clinical experience for diagnosis. Some patients may show bright red or dark red patches, which may temporarily fade under external pressure and return to the original state after pressure is removed. 3.Some other patients’ skin may appear red, purple, purplish-red, etc. and protrude from the surface of the skin, in which case they should go to a regular hospital for relevant examination and should not delay the disease. 4.When the disease of hemangioma is more serious and cannot be accurately identified by visual observation, we should do auxiliary instrument examination, usually ultrasound, angiography, MRI, CT, etc. to confirm the diagnosis. In addition, there are also puncture, pathological examination and nuclear examination to assist doctors in making more accurate judgments about hemangioma disease. However, the specific tests that need to be done need to be determined by the patient’s condition and the doctor. We should not worry too much about the disease, because most of the skin hemangiomas grow on the epidermis, in general, professional doctors can achieve clinical diagnosis through visual inspection or simple examination, which can reduce the burden of the families of the affected children and avoid unnecessary expenses. Secondly, since 85% of the skin hemangiomas are in children, the radiation caused by the examination equipment to children can be reduced to avoid affecting their development. Finally, only individual children suspected of having cutaneous hemangioma with visceral hemangioma need targeted examination, and can draw on relevant testing equipment for auxiliary examination. After the disease is diagnosed, active treatment is required for early recovery. The above is a specific introduction to the diagnosis of hemangioma. Parents of children with hemangioma should not take it lightly and let it go, nor should they easily conclude that it is hemangioma when they find symptoms similar to hemangioma and use drugs indiscriminately. Because the cause of this disease is complex, the performance varies, and some of the symptoms are not obvious, it is necessary to find a professional hospital and a professional doctor in time. Doctors will choose different examination methods according to the child’s condition. Generally, under the guidance of experienced doctors, we can avoid detours, reduce some unnecessary examination items, save time and money, and achieve the purpose of diagnosing and treating hemangioma.
