Neck hemangioma symptom?

summary

Cervical hemangioma is a congenital disease. It is a kind of vascular disorder in a certain stage of embryonic development, which makes its morphology stop at this stage. 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. Neck hemangioma symptom? Let's talk about it

Neck hemangioma symptom?

The symptoms and signs of cervical hemangioma depend on the type, size, location, depth and extent of the tumor. Most hemangiomas invade more superficial tissues, such as skin and subcutaneous tissues; The invasion of muscles, deep blood vessels, larynx, pharynx, cervical spine and other tissues was less. If it has invaded deep tissue, there are some corresponding symptoms, such as dysphagia, respiratory tract obstruction, hematemesis, massive hemorrhage, etc.

X-ray examination of the neck is valuable to understand the size and extent of the deep tumor or whether the tumor invades the cervical or laryngeal cartilage. If preoperative angiography can find out the nutrient branches of hemangioma, ligation of supply vessels at both ends of hemangioma can reduce intraoperative bleeding, which is conducive to complete resection of hemangioma.

According to the clinical manifestations, the diagnosis of cervical hemangioma is not difficult, but if it invades some important organs in the deep neck, such as carotid artery and larynx, special attention should be paid. Puncture of the tumor is very helpful for diagnosis. If blood is drawn out, the diagnosis can be made.

matters needing attention

The larger hemangioma can be removed by stages. If there is a connection between the hemangioma and the carotid artery, special care should be taken during the operation to avoid massive hemorrhage. Postoperative residual hemangioma can be treated with radiotherapy or other therapies.
