Intracranial venous malformations are abnormally enlarged veins in brain. Venous malformations are a type of blood vessel abnormality in the brain or spinal cord.
Intracranial developmental venous anomalies (DVAs), otherwise known as venous malformations or venous angiomas, are assumed to be congenital abnormalities of venous drainage through which blood flows at low velocity. DVAs occur sporadically, perhaps due to ischemia during intrauterine life causing the development of aberrant venous architecture,1 but they occasionally obey a dominant pattern of inheritance due to a gene mutation on the short arm of chromosome 9, which is thought to alter early venous development.2,3 DVAs sometimes coexist with other intracranial vascular malformations, usually cavernous malformations of the brain (CMs).
The most important goal AVM treatment is to prevent internal bleeding from rupture, because which can lead to stroke / death. However, seizure control or stabilization of progressive neurological deficits are occasionally treatment goals. Though medication may be prescribed, it does not cure AVMs but medications are used to control pain and seizures. The management options for brain AVMs include observation or various treatment techniques, such as endovascular embolization, microsurgical techniques and stereotactic radiotherapy used alone or in combination with varying degrees of treatment-associated morbidity and mortality.
