VASCULAR MALFORMATIONS

VASCULAR MALFORMATIONS

Vascular malformations are congenital abnormalities of the brain vascular system and of the spinal cord vascular system, which are classified as:

 

Brain aneurysms: which are pathological enlargements of the lumen of an artery.

Vascular malformations - Causes

 

The main cause of vascular malformations is accidental abnormalities caused in the cerebral vessels during fetal development.

 

Vascular malformations - Symptoms

 

The most common symptoms of vascular malformations include:

 

• subarachnoid hemorrhage
• intraventricular hemorrhage
• epileptic seizure
• intracerebral hemorrhage
• headache
• decreased visual acuity
• ophthalmoplegia
• psychological disorders

 

The following treatment methods of vascular malformations are recommended: surgical removal of accessible malformations, embolization of selected malformations usually in conjunction with focused radiation (γ-knife radiosurgery or gamma knife surgery).

 

In any case, the site, the magnitude of the lesion, the age of the patient, the degree of neurological dysfunction and the general health condition of the patient should be taken into account so as to determine the optimal therapeutic approach.
