What medicine does orbital vein sex hemangioma take?
summary
We all know that the eye is the window of the soul, its importance is self-evident. But many eye diseases threaten our window of mind. So how can we stay away from these threats? I think only when we understand the occurrence of some eye diseases can we effectively avoid damage. Next, let's learn something about orbital venous hemangioma.
What medicine does orbital vein sex hemangioma take?
If the orbital margin is palpable, anterior orbital incision, skin incision or conjunctival incision are usually used. After incision of skin, subcutaneous tissue, orbicularis muscle and orbital septum, purplish red tumor can be found, which often adheres to surrounding tissues. First, identify the relationship with levator palpebrae superioris, superior oblique muscle, medial rectus muscle and supraorbital nerve, and then blunt separation, such as adhesion with muscle and tendon, and fibrous cord extending into the surrounding fat, sharp dissection along the surface of the tumor and its vascular cavity, so as not to damage the functional structure. If the tumor has invaded the extraocular muscle or surrounded the optic nerve, it can only be resected mostly, especially in the orbital apex. The hard fibrous tissue will wrap the abnormal blood vessels, rectus muscle and optic nerve into a mass, which is more difficult to resect completely. This kind of case often has recurrence after operation. For the orbital venous hemangioma that cannot be completely resected, radiotherapy and radiotherapy are recommended γ It can be used for reference. The tumor is located in the medial or lower part of the orbit. Abnormal blood vessels are exposed under the conjunctiva. The tumor can be removed through conjunctival incision without scar. Sclerosing agent or pingyangmycin injection can also be used in patients limited to the anterior part of the orbit.
The etiology of venous hemangioma is unknown. Because the tumor often occurs in childhood, the composition of the tumor is more complex, in addition to veins, it is often accompanied by capillaries, rich fibrous tissue, some scholars believe that it is developed from capillary hemangioma, that is, most of the patients with capillary hemangioma spontaneously subside in the process of human growth. About 25% of the patients with fibrous hyperplasia, capillary hemangioma degeneration is not complete, and developed into a larger vein, the formation of vascular fiber tissue mass. However, this hemangioma is often multiple, mostly in the eyelids, head and neck and oral submucosa, some cases were found at birth or shortly after birth, so it may be angiodysplastic hamartoma in late fetal or postnatal.
Examination items: three mirror, immunopathological examination, X-ray examination, B-type ultrasonic examination, contrast enhanced CT scan, plain CT scan, and MRI examination of facial features. Histopathological examination: on the operating table or pathological specimens, it was found as a purple red mass without capsule, with extensive adhesion to the surrounding muscles and optic nerve, even involving the extraocular muscles, with fibrous cords extending into the orbital fat. The typical shape is large at the front end and small at the back end, with a few veins connected to the orbital apex. There was a large purple black blood cavity in the tumor. This kind of blood cavity can have many, and do not communicate with each other, showing purple grape shape (Fig. 2). The blood supply and drainage vessels of the tumor are veins, the blood flow is slow, and thrombosis is easy to occur. Purple black thrombus and phlebolith can be seen in the cut specimen. Microscopically, there was no capsule, and the tumor was mainly composed of veins with different diameters and pieces of fibrous tissue (Fig. 3). The thickness of the venous wall is different, the lumen is cystic, and it is sinusoidal in the thin-walled vascular area. Sometimes it is diagnosed as cavernous hemangioma. It is also often found that endothelial cells gather with only a few capillaries. Therefore, some people think that this tumor is the development of capillary hemangioma with incomplete spontaneous degeneration. There are more fibrous stroma in the lumen than in the cavernous hemangioma, and the main body of the tumor is composed of crisscross fibrous cells. There are many pieces of red blood cells and lymphocytes, foreign body macrophages and fat cells in the stroma, and striated muscle is common in the edge. Fat and rhabdomus may be caused by the enlargement of the tumor or the invasion of adhesion.
matters needing attention
Orbital venous hemangioma is still unknown. Understanding the risk factors of tumor and formulating corresponding prevention and treatment strategies can reduce the risk of tumor. We should pay attention to and improve those factors closely related to our life, such as smoking cessation, reasonable diet, regular exercise and weight loss. Appropriate exercise, enhance the physique, improve their disease resistance. Anyone who follows these simple and reasonable lifestyle knowledge can reduce the chance of orbital venous hemangioma.
