Some people don’t care about the existence of hemangioma disease at all, which will directly lead to the slow deterioration of hemangioma disease. For the hazards of hemangioma disease, I believe that we must not know much about it, here let’s have a detailed understanding of the three major hazards of hemangioma disease, and hope that it will be helpful to the patients. 1.Harm to visual system and auditory system: visual periorbital hemangioma has greater visual impact, especially the hemangioma of upper eyelid, which can cause intractable astigmatism, myopia and strabismus. Posterior bulbar capillary hemangioma can cause blindness. In advanced stages, it can cause ptosis and protrusion of the eyeball. Lower eyelid hemangiomas have a lesser effect on vision. Hearing Hemangiomas located in the parotid gland can obstruct the external auditory canal, resulting in varying degrees of conductive hearing loss. If the hemangioma can’t degenerate by itself and affects the hearing of children for a long time, it can affect the formation of their speech ability. Harm to respiratory system: large hemangiomas of tongue and blowing pharynx in respiratory system can block the respiratory tract, and large hemangiomas in neck can compress the trachea, resulting in severe respiratory difficulties, which can lead to death of the child by suffocation in severe cases. Harm to internal organs and bones: congestive heart failure is a fatal complication for children with multiple subcutaneous and visceral hemangiomas. The incidence of heart failure in multiple subcutaneous hemangiomas without visceral hemangiomas is not high, but due to the abnormal traffic of extensive and tiny arteries and veins, it can produce significant reduction of peripheral vascular resistance, and thus make the cardiac output increase significantly, and there is shortness of breath, accelerated heart rate and enlarged heart. Skeletal damage and limb deformities mainly occur in large limbs and cavernous angiomas of the head and face. Due to the presence of arteriovenous anastomotic branches in the deep tissues of the affected limbs and around the bones, blood flow increases, the bone marrow is rich in circulation and blood oxygen increases, which contributes to the thickening and growth of the affected limbs. Skeletal hemangioma can produce destructive changes of bone quality, and then pathological fracture can be produced. Has the harm of hemangioma disease been understood? The existence of hemangioma disease seriously affects the health of the patient’s body, and in serious cases, the respiratory system of people will also have a great harm to the patient’s internal organs and bones are very harmful, I hope that people can pay attention to the harm of hemangioma!
