Intracranial venous malformations are abnormally enlarged veins in brain. Venous malformations are a type of blood vessel abnormality in the brain or spinal cord.
Venous malformations are the most frequent slow-flow vascular malformations referred to specialized centers.Most of them are sporadic, and unifocal (VM, 93%), although 1% are multifocal . Inherited forms, comprised of cutaneomucosal venous malformations (VMCM, 1%) and glomuvenous malformations (GVMs, 5%) are often multifocal.There is no sex preponderance. VMCM and GVM have an age-dependant variation in penetrance, which reaches its maximum by 20 years of age (87% for VMCM and 93% for GVM).
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.
