Surgery for cerebral vascular malformations

Cerebral vascular malformation surgery is a surgical procedure we use to treat abnormalities in the blood vessels of the brain that can cause health problems.

These malformations can include arteriovenous malformations (AVMs), cavernomas and arteriovenous fistulas, among others. They can be congenital (present from birth) or acquired throughout life.

While some people can live with these malformations without symptoms, others may experience serious complications such as brain haemorrhages, seizures, severe headaches or neurological deficits.

Benefits of surgery for cerebral vascular malformations

Surgery for cerebral vascular malformations involves the identification and removal, or correction, of these malformations, reduces the risk of complications and improves the patient’s quality of life. The main goal of surgery is to prevent bleeding in the brain and to alleviate the symptoms associated with the malformation.

Types of surgery for cerebral vascular malformations

Arteriovenous malformations (AVM)

Gliomas are a type of brain tumour that originate in glial cells, which are the support cells of the
central nervous system. Surgery is a treatment that offers the possibility of completely removing the primary tumour,
which can help reduce pressure on surrounding brain structures and alleviate
neurological symptoms that may be causing it.
In many cases, surgery relieves symptoms caused by the tumour, such as headaches, vision problems,
seizures and neurological deficits. Esto puede mejorar significativamente la calidad de vida del paciente.

Cavernous angiomas
Cerebral vascular malformation surgery is a suitable treatment option for cavernous
angiomas for several reasons. This surgical procedure aims to eliminate the risk of cerebral haemorrhage
by completely removing the cavernous angioma, thus alleviating associated symptoms and preventing
future complications. Surgery can significantly improve the patient’s quality of life by restoring normal
brain function and allowing for a more active and carefree life.

Arteriovenous fistulas
Arteriovenous fistulas (AVF) are a type of vascular malformation in which there is an abnormal direct connection
between arteries and veins, without the normal intermediate capillary system. This causes blood flow
abnormally fast and straight from the arteries into the veins, which can cause a number of problems,
including risk of haemorrhage, heart failure, and neurological damage. Surgery is an appropriate treatment option
for arteriovenous fistulas because it can help prevent bleeding, alleviate symptoms, normalise
the blood pressure and prevent long-term complications by correcting the vascular abnormality and restore the
blood flow in the brain.
