Stomatology

Signs and symptoms of venous malformations

Occurs on the cheeks, neck, eyelids, lips, tongue, or bottom of the mouth. The location is different, if the location is darker, the skin or mucous membrane is normal; if the location is lighter, the skin is blue or purple. The boundaries are not very clear. The ridges are soft and can be compressed, sometimes reaching vein stones. When the head is lowered, the lesion area becomes congested and swollen; after returning to the normal position, the swelling also shrinks and returns to its original state. This is called a positive body movement test. When the volume of venous malformation is not large, there is generally no subjective symptoms. If it continues to develop and grow up, it can cause facial and lip, tongue and other productive and functional disorders. If an infection occurs, it can cause pain, swelling, surface skin or mucosal ulcers, and there is a danger of bleeding.

Venous malformation pathophysiology

The old classification is called cavernous hemangioma, which is composed of countless blood sinuses of endothelial cells. Blood sinuses vary in size and shape, such as sponge structures. Sinus blood coagulates to form a thrombus, which can be calcified into vein stones.

Diagnosis of venous malformations

For arteriovenous malformations, venous malformations in deep tissues, macrocystic lymphatic malformations, etc., in order to determine their location, size, scope and anastomosis, ultrasound, angiography, tumor angiography or magnetic resonance angiography (MRA ) To assist in diagnosis.

Venous malformation treatment plan

Treatment of vascular or vascular malformations should be determined based on factors such as the type of lesion, location, and age of the patient. Current treatment methods include surgical resection, radiation therapy, hormone therapy, hypothermia, laser therapy, and sclerotherapy. Comprehensive treatment is generally used. Hemangiomas in infants and young children should be observed. If the development is rapid, certain interventions should also be given in time.
