Is scalp venous malformation hereditary?

Venous malformations often appear on the face, on the brain, and in places containing veins. These venous malformations have a great impact on our body, so we must pay attention to them and find reasonable treatment methods. Because the condition of the disease is different, it must be diagnosed into different categories so that everyone can have enough understanding.

Symptoms and signs

It often occurs on the cheeks, neck, eyelids, lips, tongue or floor of the mouth. The depth of the spot varies. If it is deeper, the skin or mucous membrane will be normal in color; if it is lighter, it will appear blue or purple. The borders are not very clear, it feels soft and can be compressed, and sometimes phleboliths can be felt. When the head is in a low position, the affected area becomes swollen with blood; after returning to its normal position, the swelling also shrinks and returns to its original state. This is called a positive position shift test. When the venous malformation is small, there are generally no symptoms. If it continues to develop and grow, it may cause deformation and functional disorders of the face, lips, tongue, etc. If infection occurs, it may cause pain, swelling, ulcers on the surface of the skin or mucous membranes, and there is a risk of bleeding.

Pathophysiology

The old classification was called cavernous hemangioma, which is composed of countless blood sinusoids of endothelial cells. The blood sinuses vary in size and shape, like a sponge structure. The blood in the sinus cavity coagulates to form a thrombus and may calcify into a phlebolith.

Diagnostic tests

For arteriovenous malformations, venous malformations in deep tissues, large cystic lymphatic malformations, etc., in order to determine their location, size, range and anastomosis, ultrasound, arteriography, aneurysm cavity angiography or magnetic resonance angiography (MRA) can be used to assist in diagnosis.

Treatment options

The treatment of blood vessels or vascular malformations should be determined based on factors such as the type and location of the lesion and the age of the patient. Current treatments include surgical resection, radiotherapy, hormone therapy, cryotherapy, laser therapy, sclerotherapy, and injection of sclerosing agents. Generally, a combination of treatments is used. Hemangiomas in infants and young children should be observed, and if they develop rapidly, timely intervention and treatment should be given.
