cerebral arterial disease

Cerebral arteriosclerosis, also known as cerebrovascular disease, refers to a range of conditions that affect the blood vessels of the brain and the cerebral circulation. This can lead to impaired blood flow to the brain, causing various symptoms and complications.

Causes and Risk Factors

• Damage or deformation of arteries supplying oxygen and nutrients to the brain [13]
• Ischemic strokes or mini-strokes, which are often a presentation of cerebrovascular disease [13]

Symptoms and Complications

• A stroke or cerebrovascular accident (CVA) can occur due to compromised cerebral perfusion or vasculature [11]
• Signs and symptoms may include:
  • Bleeding in the brain, leading to a hemorrhagic stroke
  • Treatment may involve medications or surgery

Types of Cerebral Arterial Disease

• Ischemic strokes: account for approximately 85% of all strokes [1]
• Hemorrhagic strokes: account for the remaining 15% of all strokes [1]

Risk Factors in Children

• Congenital heart problems
• Head trauma
• Blood-clotting disorders
• Sickle cell disease, which can cause narrowing of brain arteries (a significant risk factor for Black children) [14]

Treatment Options

• Intracranial stent placement
• Medications
• Surgery, such as superficial temporal artery to middle cerebral artery bypass surgery [15]

Cerebral Arterial Disease Signs and Symptoms

Cerebral arteriosclerosis, a condition where the arteries supplying blood to the brain become narrowed or blocked due to plaque buildup, can lead to various signs and symptoms. These may include:

• Transient Ischemic Attack (TIA) or Stroke: A blockage or narrowing in the carotid artery can cause a TIA or stroke, which may result in:
  • Trouble with vision or speech
  • Confusion
  • Dizziness
  • Drooping on one side of the face
  • Loss of feeling, muscle strength, or weakness on one side of the body
  • Severe headache
  • Vision loss in one eye
• Chest Pain: Atherosclerosis in the arteries close to the heart can lead to coronary artery disease, causing chest pain.
• Heart Attack or Heart Failure: Untreated coronary artery disease may result in a heart attack or heart failure.

Other Complications

In addition to these symptoms, cerebral arteriosclerosis can also cause:

• Aneurysm: A weakened area in the artery due to abnormal stretching from plaque buildup, which can burst and cause bleeding in the brain.
• Hemorrhagic Stroke: An aneurysm can lead to a hemorrhagic stroke, which is a life-threatening condition.

Treatment and Prognosis

Early detection and treatment of cerebral arteriosclerosis are crucial to prevent these complications. Treatment may include medications or surgery. The prognosis depends on the severity of the disease and promptness of treatment.

Diagnostic Tests for Cerebral Arterial Disease

Cerebral arterial disease, also known as carotid artery disease, can be diagnosed using various imaging tests and physical examinations.

• Ultrasound: A noninvasive test that uses high-frequency sound waves to view the carotid arteries in the neck. It can show buildup of fatty deposits called plaques and blood flow in the carotid arteries [1].
• CT or MRI Angiogram: These imaging tests can provide a detailed view of arteries in the brain and neck, including any blockages or narrowing [2]. They are less common than ultrasound but can be used to diagnose cerebral arterial disease.
• Cerebral Arteriogram: A catheter-based exam that provides a detailed view of blood vessels in the brain, head, and neck. It is usually done after other imaging tests show a problem [3].
• Physical Exam: A healthcare provider may perform a physical exam to check for symptoms such as balance issues, vision loss, headaches, and difficulty speaking [4].

Other Diagnostic Tests

• Transcranial Doppler (TCD) Ultrasound: This test looks exclusively at the blood vessels and blood flow within the body. It can be used to diagnose cerebral arterial disease [5].
• Perfusion Imaging: Uses CT or MRI technology to measure blood flow to the brain, helping doctors assess the extent of brain damage in stroke or how the brain tissue is getting its blood [6].

Symptoms and Conditions

Medications Used to Treat Cerebral Arterial Disease

Cerebral arterial disease, also known as intracranial atherosclerosis (ICAS), is a condition where the arteries in the brain become narrowed or blocked due to the buildup of plaque. This can lead to reduced blood flow to the brain and increase the risk of stroke.

Current Treatment Options

Several medications have been shown to be effective in treating cerebral arterial disease:

• Antiplatelet drugs: These medications, such as aspirin, prevent platelets from clumping together and forming blood clots that can block arteries. Aspirin is commonly used to treat patients with carotid artery disease, especially those who have had a transient ischemic attack (TIA) or stroke [8].
• Anticoagulants: These medications, such as warfarin, prevent the formation of blood clots by inhibiting the production of vitamin K-dependent clotting factors. However, anticoagulants are not commonly used to treat cerebral arterial disease due to their increased risk of bleeding complications [15].
• Pentoxifylline: This medication is indicated for the treatment of patients with intermittent claudication due to atherosclerosis or other obstructive arteriopathies [9].

Emerging Treatment Options

Newer medications and treatments are being investigated to improve outcomes in patients with cerebral arterial disease:

• Cilostazol: This medication has been shown to reduce recurrent ischemic stroke, with fewer hemorrhagic events compared to aspirin [3].
• Trackable drug-coated balloons: These devices are being developed for the treatment of primary or restenotic arteries and may offer improved outcomes in patients with ICAD [13].

Expanded Access

In some cases, expanded access to investigational medical products (drugs, biologics, or medical devices) may be available for patients with cerebral arterial disease who have not responded to standard treatments. This option should be discussed with a healthcare provider on an individual basis [10][11].

Differential Diagnosis of Cerebral Arterial Disease

Cerebral arterial disease, also known as intracranial atherosclerosis (ICAD), is a condition where the arteries in the brain become hard and narrow due to the buildup of plaque. Accurate diagnosis is crucial for effective treatment and management of this condition. Here are some key points to consider:

• Transient Ischemic Attack (TIA) vs. Acute Stroke: A TIA, also known as a "mini-stroke," is a temporary disruption of blood flow to the brain that resolves within 24 hours. In contrast, an acute stroke is a more severe and permanent disruption of blood flow.
• Cerebral Venous Thrombosis (CVT): CVT is a rare condition where a blood clot forms in one of the veins draining blood from the brain. This can cause symptoms similar to those of ICAD, such as headache, seizures, and weakness on one side of the body.
• Reversible Cerebral Vasoconstriction Syndrome (RCVS): RCVS is a condition where the blood vessels in the brain constrict or narrow, leading to temporary symptoms such as headache, nausea, and visual disturbances. This condition can be mistaken for ICAD due to similar symptoms.
• Large and Medium Vessel CNS Vasculitis: This is an inflammation of the blood vessels in the central nervous system (CNS), which can cause symptoms similar to those of ICAD, such as stroke, seizures, and cognitive decline.

Key Factors to Consider

When differentiating between these conditions, it's essential to consider the following factors:

• Clinical Presentation: The severity and duration of symptoms, as well as any changes in mental status or level of consciousness.
• Imaging Studies: CT and MRI scans can help identify areas of ischemia or infarction, as well as signs of inflammation or vasculitis.
• Laboratory Tests: Blood tests can help rule out other conditions that may mimic ICAD, such as infections or metabolic disorders.
