What are central nervous system vascular malformations?

Central nervous system vascular malformations are the rare problems involving the blood arteries in the brain or spinal cord and their membrane coverings.

What are the types of central nervous system vascular malformations?

Vascular anomalies of the central nervous system exist in several forms, among them being:

• AVMs or arteriovenous malformations: They are abnormal blood vessel tangles that connect veins and arteries. An AVM can occur anywhere in the body. It usually occurs on or near the spinal column or within the brain. The largest threat of brain haemorrhages and other complications is connected with this type.
• Telangiectasia of the capillaries: These are capillaries, which are very minute blood vessels and larger than usual.
• Abnormalities of the caverns: These are abnormally developed blood arteries in the brain or spinal cord. They resemble popcorn or mulberries.
• Arteriovenous fistulas in the dura: These are peculiar connections between arteries, a draining vein, and the dura, the hard covering that covers the brain or spinal cord.
• Venous malformations: These are abnormally enlarged veins in the brain or spinal cord. They also are called developmental venous anomalies.

What are the symptoms of central nervous system vascular malformations?

The symptoms depend on the type and place of the central nervous system vascular abnormality. There are even vascular abnormalities that may not cause any symptom, and they may be detected through imaging for another purpose.

Some vascular abnormalities of the central nervous system may cause the following symptoms:

• Bleeding.
• Seizures.
• A headache.

The neurological impairments constitute all disorders of the brain and nervous system that deteriorate over time. Speech, eyesight, balance, and memory can be affected by neurological deficiencies.

What causes central nervous system vascular malformations?

It is not known why central nervous system vascular malformations occur. Some are congenital, that is, they are present at birth. Others occur later. Certain genetic conditions increase the risk for having a vascular malformation. Central nervous system injury might also be a cause.

What are the complications associated with central nervous system vascular malformations?

It results from vascular abnormalities of the central nervous system leading to brain or spinal cord injury. Damage could be caused through hemorrhage or bleeding into adjacent tissues. Others include exertion of pressure in certain areas of the brain or spinal cord and causing inability to attain tissues.

Some of the complications include:

• Stroke.
• Rupture of the blood artery and causing harm to the brain.
• Death.
• Issues of children's behaviour and learning.

The risk of recurrence of a bleeding episode is high after the first episode. Pregnancy may predispose an individual with vascular abnormality to bleed more easily.

How is central nervous system vascular malformations diagnosed?

A medical professional seeks a family history of stroke, epilepsy, or similar disorders to diagnose a vascular abnormality of the central nervous system. The term bruit refers to the whooshing sound produced by some vascular abnormalities. The bruit is caused by rapid blood flow via an abnormality. A stethoscope may be used by a provider to hear the sound.

Imaging examinations

• Imaging studies and angiograms can find vascular malformations in the central nervous system. An angiography is the picture that will show the movement of blood with the use of veins or arteries. With a contrast dye introduced to the blood, the picture will reveal blood vessels. It lights up the dye on the scan.
• Computerised tomography or magnetic resonance angiography might be used for the diagnosis and treatment of vascular abnormality in the central nervous system.
• Some vascular malformations, for example, cavernous malformations, can be identified using routine MRI or CT scans.

What is the treatment for central nervous system vascular malformations?

The course of treatment for a central nervous system vascular malformation is determined by its kind, location, symptoms, and bleeding risk. Sometimes it is enough just to observe some changes in deformity and possibilities of bleeding.

Medications

Anti-seizure medications and headache pain relievers are the two pharmaceuticals that may be used to treat the symptoms of a venous malformation.

Surgery or other treatments

Some of the central nervous system vascular abnormalities carry a high risk of bleeding and can be treated. The treatment depends on the abnormality.

• Surgery: To remove the deformity, this requires surgical incisions into the brain or spinal cord. The most common cause of surgery is a small, easily accessible arteriovenous malformation.

Any surgery contains risks of the infection and the blood loss as well. Harm to healthy tissues in the place is also probable.

• Radio surgical stereotactic technique: The radiation beam used in radio surgical stereotactic technique targets with precision the blood vessel abnormality. The shape of the abnormality disappears in time due to the destruction caused to the walls by the radiation used.

The dangers are lowered with radio surgery compared to that of traditional surgery since no cutting is involved, though healthy tissue might be injured by radiation.

• Embolisation of the blood vessels: This method makes use of a catheter, which is a long, thin tube. The tube is inserted into the leg or groin artery that supplies blood to the deformity. After that, it is guided by X-ray imaging and threaded to the brain.

The surgeon inserts coils or a glue-like material into the tube to obstruct the artery and reduce blood flow to the abnormality.

It may not be totally eradicated by embolisation, or the result may not be persistent. Frequently, it occurs in association with other surgical interventions.

What to expect from doctor?

You may be asked the following questions from your provider:

• Do you have episodic or persisting symptoms?
• How severe are your symptoms?
• What seems to improve your problems, if anything?
• What seems to bring on your symptoms, if anything?
