How does arm hemangioma return a responsibility?

summary

Hemangioma is the most common benign tumor in infants. Patients are required to pay enough attention to the treatment of this disease. The incidence rate is about 4% - 10%. It is usually seen in girls, which is about 3-5 times of boys. The incidence of white race is higher than that of yellow race, which is rare in black race. The incidence of premature low birth weight infants (birth weight less than 1 kg) is as high as 25%, and the incidence of twins is also relatively high. So we must do a good job in the related work of this disease, then how about the hemangioma of the arm?.

How does arm hemangioma return a responsibility?

First, most scholars believe that in the process of human embryonic development, especially in the early stage of vascular tissue differentiation, due to the small-scale dislocation of its control gene segment, it leads to abnormal tissue differentiation in specific parts and develops into hemangioma. Some scholars believe that in the early stage of embryo (8-12 months), the embryonic tissue suffered mechanical damage and local tissue bleeding, resulting in the distribution of some hematopoietic stem cells to other embryonic cells, some of which differentiated into angioid tissue and eventually formed hemangioma.

Second: hemangioma is composed of a large number of proliferative blood vessels. At the early stage of embryo, the primitive vessel is a kind of tube made up of endothelial cells, which forms a dense network in the middle of the stroma. Later, with the development of various organs, the primitive vascular network gradually differentiated into many vascular plexus and lymphatic plexus associated with organs.

Thirdly, the embryonic development of blood vessels can be divided into three stages: plexiform stage, reticular stage and tubular stem stage. If there is an obstacle or abnormality in the normal development of a certain stage, the deformity of the normal development of that stage may appear. In the plexiform phase, if some capillaries stop developing, they will produce capillary hemangioma; In the reticular phase, cavernous hemangioma can be seen if the enlarged vessels are clustered and tend to fuse together.

matters needing attention

Found with hemangioma should actively to our regular hemangioma hospital treatment. According to the type, location, size and blood flow of vascular malformation, the treatment method will be selected. The principle of treatment is not only to cure the disease, but also to give consideration to the shape and function of the face.
