Neurovascular disease and syndromes

Neurovascular lesions are abnormal growths or masses that develop within the blood vessels supplying blood to the brain and spinal cord.

These lesions can occur in various parts of the body.

Types of Neurovascular Lesions

There are several types of neurovascular lesions, including:

• Atherosclerosis: This occurs when plaque builds up in the arteries, reducing the flow of blood and oxygen to the brain.

• Arteriovenous malformations (AVMs): These are abnormal tangles of blood vessels that form between the arteries and veins.

• Cerebral aneurysms: These are weakened areas in the blood vessels of the brain, which can rupture and cause bleeding in the brain.

• Dural arteriovenous fistulas (DAVF): These are abnormal connections between the arteries and veins on the surface of the brain.

Symptoms of Neurovascular Lesions

The symptoms of neurovascular lesions can vary depending on the specific type of lesion and its location.

Diagnosis of Neurovascular Lesions

Diagnosing neurovascular lesions typically involves a combination of physical exams, imaging tests, and lab tests. Your doctor may perform a neurological exam to check your reflexes, muscle strength, and sensory function. They may also order imaging tests, such as a CT scan, MRI, or angiogram, to get a closer look at the blood vessels in the brain and identify any abnormalities.

Treatment of Neurovascular Lesions

The treatment for neurovascular lesions typically depends on the specific type of lesion and its location. Treatment options for these lesions include:

• Embolization: This is a minimally invasive procedure that involves injecting a substance into the blood vessels to block the flow of blood to the lesion.

• Surgery: In some cases, surgery may be necessary to remove the lesion.

• Radiation therapy: Radiation therapy can be used to shrink lesions or stop their growth.
