Misconceptions: cavernous hemangioma and trapezius hemangioma. Numerous studies have shown that the so-called “cavernous hemangiomas” and “trabecular hemangiomas” are not tumors, but rather congenital vascular malformations associated with the formation of blood vessels during embryonic development. Therefore, they are currently defined as “venous malformations” and “arteriovenous malformations”, respectively. Myth: Capillary malformations are caused by an increase in the number of capillaries. It is believed that capillary malformation is a posterior microvenous malformation, not a disease caused by an excessive number of capillaries. Myths of treatment: Myth: Surgical excision is the preferred treatment option for venous malformations. Venous malformations not only involve the skin, subcutaneous fat, but also often invade into the muscle and are diffusely distributed. Surgical excision of venous malformations alone not only tends to disrupt function but also fails to deal with lesions within the muscle with poor results. Treatment of venous malformations can be done by sclerotherapy, and for problems that cannot be completely eliminated by this, other treatments such as surgery and laser can be considered to “add to the mix”. Surgical treatment can sometimes be “catastrophic” for venous malformations. Myth: Radiation therapy and isotope therapy can be the conventional treatment for venous malformations. Radiotherapy can destroy blood vessels, but it cannot be the conventional treatment for vascular malformations, considering the combination of efficacy and damage to normal tissue. Myth: Arteriovenous malformations can be treated by simply blocking the well-known blood supply arteries. Arteriovenous malformations are not the same as arteriovenous fistulas or aneurysms, which have multiple blood supply arteries. Unless all the blood supplying arteries of the lesion are blocked, the other arteries will compensate and instead lead to an aggravation or even catastrophic condition. Myth: The safety of sclerosing agents Sclerosing agents are double-edged swords that can bring healing and danger. The use of alcohol in arteriovenous malformations, for example, can even lead to organ loss and death if the techniques and risks involved are not adequately understood. Myth: Inadequate imaging judgment prior to surgical excision. For special sites, such as cranial sites and spinal sites where lesions exist with the possibility of CNS traffic, rash surgery may lead to serious complications. Myth: The surgical excision process should still be radical. For example: for the breast area of female infants, surgery can easily affect breast development problems, in addition, parotid denervation lesions for the facial nerve, etc., should be more cautious.
