Vascular spiders

classification

Vascular nevus isbabyThe most common benign tumor, is formed by the hyperplasia of embryonic vascular network.

Vascular nevus is divided into two kinds, hemangioma and vascular malformation.

For the growth of blood vessels and vascular malformation can never fade.

Hemangioma, is caused by the proliferation of vascular endothelial cells.Clinically to strawberry hemangioma and cavernous hemangioma is relatively rare.It is generally believed that hemangioma natural course can be divided into: stage hyperplasia, stability, fade.Hemangioma grow in the neonatal period quickly, is generally not life-threatening.In aged 1 to 1 and a half into the plateau.75% ~ 80% of the children at the age of seven, hemangioma is expected to reach full regress.

For the treatment of hemangioma, generally should establish the concept of active treatment, on the basis of correct diagnosis, according to the specific situation to choose the following methods:

(1) laser treatment, in recent years, applied laser treatment of superficial vascular disease are common.

(2) the hormone therapy, local hormone injections and oral corticosteroid therapy.

Radiation therapy (3), generally does not claim toThe childUse.

(4) frozen.

(5) surgery.

(6), were followed for growth is not obvious or entering plateau, fading period is the preferred means of hemangioma.

Treatment method and principle

The principle of laser treatment for vascular nevus: is to use hemoglobin inside capillaries in near 590 nm wavelength absorption peaks and the surrounding normal tissue absorption is less, and in each pulse of the interphase heat dissipation characteristics and principles of the laser beam thermal coagulation effect of hemoglobin, lead to vascular occlusion, and make the vascular spiders stopped growing, and finally disappear.And rely on selective solar-thermal role.

Other treatments include: hormone therapy, local hormone injections and oral corticosteroid treatment;Radiation therapy, generally do not advocate for children use;Follow-up observations, for growth is not obvious or enter a plateau, fading period is the preferred means of hemangioma.Frozen;Surgical treatment, etc.

Vascular spiders is the most common benign tumor of the baby, is formed by the hyperplasia of embryonic vascular network.Vascular nevus points hemangioma and vascular malformation, for the growth of blood vessels and vascular malformation can never fade.Hemangioma, is caused by the proliferation of vascular endothelial cells.Clinically to strawberry hemangioma and cavernous hemangioma is relatively rare.Treatment of vascular nevus method has a lot of kinds, at present is generally believed that the laser is the preferred treatment.
