Arteriovenous hemangioma

Introduction to Arteriovenous Arteriovenous hemangioma (arteriovenoushemangioma) was first reported by Biberstein and Jessner in 1956 as a varicose aneurysm Cirsoidaneurysm. This disease is a benign tumor. Some people think that it is derived from the cutaneous arteries. Some people think that it may be a hamartoma of the vascular ball Sucquet-Hoyer tube. Sexual proliferation. basic knowledge The proportion of illness: 0.001% Susceptible people: good for middle-aged and elderly Mode of infection: non-infectious Complications: hearing impairment

Causes of arteriovenous aneurysm

The lesion is located in the upper and middle parts of the dermis, which is more limited and has no capsule. It can be seen that the thick-walled and thin-walled blood vessels containing monolayer endothelial cells are tightly aggregated, and the endothelial cells have occasional protrusions, which are likely to be veins. The thick-walled vessel wall is mainly fibrous tissue. However, most of them also contain some smooth muscles. Most of the lumens have red blood cells. Occasionally, blood clots are variable. There are often true arterial components, and inflammatory infiltration is often seen.

Arteriovenous hemangioma prevention

There is no effective preventive measure for this disease. Early detection and early diagnosis are the key to the prevention and treatment of this disease.

Arteriovenous hemangioma complications Complications, hearing impairment

1. Ulcers. The common complication of hemangioma is ulceration, which has an incidence of about 5%. It is most prone to occur during rapid proliferative phase or at special anatomical sites (upper lip, upper chest, perianal or perineal).

2. Hearing impairment. The onset of hemangioma can lead to hearing impairment in patients. The parotid hemangioma can completely block the external auditory canal and affect hearing, but it will not affect the development of the child.

3. Visual impairment. Visual impairment is also a common complication of hemangioma, and periorbital hemangioma blocks sight, leading to cost amblyopia. Even if the line of sight is unaffected, the upper hemangioma can cause astigmatism. Periorbital or intraorbital hemangioma can cause axial destruction, astigmatism, and myopia, leading to disuse amblyopia. Disuse of amblyopia is one of the common causes of blindness.

Symptoms of arteriovenous hemangioma Common symptoms Blue rubber bullae, papules, blood vessels and surrounding areas... Arteriovenous short circuit phenomenon

The disease is more common, occurs in middle-aged and elderly, occasionally seen in children, more common in men, skin lesions are single red or purple papules, ranging from 1mm to 3cm, average 4 ~ 6mm, good for head or neck It can occur on the skin or mucous membranes, usually without symptoms, and a few patients have pain or itching.

Inspection of arteriovenous hemangioma

Histopathology: clear boundaries, no capsule, shallow dermis and dermis in the middle of the dermis are composed of thick-walled and thin-walled blood vessels closely mixed, usually with thick-walled blood vessels, vascular lining as a single layer of endothelial cells, occasionally mechanized and recanalized Thrombosis, a true arterial structure with an internal elastic membrane is seen in most tumors.

Diagnosis and differential diagnosis of arteriovenous

According to the clinical manifestations, the characteristics of skin lesions, combined with histopathology can diagnose the disease.
