Pharyngeal vascular malformation

Introduction to pharyngeal vascular malformation Congenital pharyngeal malformation is an abnormal development of the embryo. Under normal development, there is a curvature between the two components of the original internal carotid artery, the third arch and the active arch. When the heart position is lowered, the curve is straightened. No longer exist. If it is not straightened and persists, an arterial ring or arterial buckling will be formed on the deep side of the pharyngeal wall or the posterior pharyngeal wall, which is close to the tonsil fossa and the posterior pharyngeal wall. It is easy to cause damage when the tonsil or pharyngeal tonsils are removed. The main cause of the disease is due to ovarian function decline, low or lack of estrogen levels in the body, reduction of glycogen in vaginal epithelial cells, vaginal pH value, and reduced ability to kill pathogens. At the same time, due to vaginal mucosa atrophy, epithelial phenotype, Insufficient blood supply, reduce vaginal resistance, facilitate bacterial invasion and reproduction caused by inflammatory lesions, in addition, poor personal hygiene habits, lack of nutrition, especially vitamin B deficiency in group B, may be related to the incidence. basic knowledge The proportion of illness: 0.003%-0.004% Susceptible people: no specific population Mode of infection: non-infectious Complications: pharyngeal foreign body

Cause of pharyngeal vascular malformation

The main reason is due to the decline of ovarian function, low or lack of estrogen levels in the body, reduction of glycogen in vaginal epithelial cells, vaginal pH value, and reduced ability to kill pathogens. At the same time, due to vaginal mucosa atrophy, epithelial venous, insufficient blood supply To reduce vaginal resistance, to facilitate bacterial invasion and reproduction caused by inflammatory lesions, in addition, poor personal hygiene habits, lack of nutrition, especially vitamin B deficiency in group B, may be related to the incidence.

Pharyngeal vascular malformation prevention

The disease is congenital disease, caused by abnormal embryonic development, and no effective preventive measures.

Pharyngeal vascular malformation complications Complications, pharyngeal foreign bodies

Or have a foreign body sensation in the pharynx.

Symptoms of pharyngeal vascular malformation Common symptoms Vascular malformation Pharyngeal foreign body sensation

According to the clinical manifestations and percussion pulsation, a preliminary diagnosis can be made. X-ray carotid angiography can identify the location and shape of vascular malformation.

Light can be asymptomatic, or have a foreign body sensation of pharynx, obstruction and pulsation, check the posterior pharyngeal wall or tonsils around the tonsils, there are obvious beats, percussion can have a sense of pulsation.

Examination of pharyngeal vascular malformation

Check to see the posterior pharyngeal wall or the swelling around the tonsils, there are obvious beats, percussion can have a sense of pulsation.

Diagnosis and diagnosis of pharyngeal vascular malformation

Should be noted with the infection of the internal carotid aneurysm, the posterior pharyngeal abscess corrodes the blood vessel wall and the pseudoaneurysm.
