Patients with basilar artery thrombosis may present with a variety of symptoms, depending on the extent and location of the blockage. Common symptoms include sudden dizziness, difficulty speaking, double vision, weakness or numbness on one side of the body, and loss of coordination. In severe cases, it can lead to loss of consciousness or coma. These symptoms occur because the brain is not receiving enough blood and oxygen.

Diagnosing basilar artery thrombosis involves a combination of clinical evaluation and imaging studies. A doctor will assess the patient's symptoms and medical history, followed by imaging tests such as a CT scan or MRI to visualize the blood vessels in the brain. A CT angiography or MR angiography may be used to specifically look at the blood flow in the basilar artery and identify any blockages.

Treatment for basilar artery thrombosis aims to restore blood flow to the brain as quickly as possible. This may involve the use of thrombolytic drugs, which dissolve blood clots, or mechanical thrombectomy, a procedure to physically remove the clot. In some cases, anticoagulant medications are used to prevent further clotting. Supportive care, including managing blood pressure and ensuring adequate oxygenation, is also crucial.

The prognosis for basilar artery thrombosis varies depending on the speed of diagnosis and treatment. Early intervention can significantly improve outcomes, but delays can lead to severe neurological deficits or death. Some patients may recover fully, while others may experience long-term disabilities. Rehabilitation therapies, such as physical and occupational therapy, can help improve function and quality of life.

The primary cause of basilar artery thrombosis is the formation of a blood clot within the artery. Risk factors include atherosclerosis (hardening of the arteries), high blood pressure, smoking, diabetes, and high cholesterol. Other potential causes include trauma, certain blood disorders, and heart conditions that increase the risk of clot formation.

Basilar artery thrombosis is relatively rare compared to other types of strokes, accounting for a small percentage of all ischemic strokes. It is more common in older adults, particularly those with risk factors for cardiovascular disease. The condition can occur in both men and women, though some studies suggest a slightly higher prevalence in men.

The pathophysiology of basilar artery thrombosis involves the formation of a thrombus (blood clot) that obstructs blood flow in the basilar artery. This artery is crucial for supplying blood to the brainstem and posterior parts of the brain. When blocked, these areas suffer from ischemia (lack of blood flow), leading to cell death and neurological symptoms.

Preventing basilar artery thrombosis involves managing risk factors for cardiovascular disease. This includes maintaining a healthy lifestyle with regular exercise, a balanced diet, and avoiding smoking. Controlling blood pressure, cholesterol, and blood sugar levels is also important. In some cases, medications such as antiplatelet agents or anticoagulants may be prescribed to reduce the risk of clot formation.

Basilar artery thrombosis with occlusion of a precerebral artery is a critical condition that can lead to a stroke. It requires prompt diagnosis and treatment to restore blood flow to the brain and minimize damage. Understanding the risk factors and symptoms can aid in early detection and improve outcomes. Prevention focuses on managing cardiovascular health and reducing the risk of clot formation.

If you or someone you know experiences sudden symptoms like dizziness, difficulty speaking, or weakness on one side of the body, it is important to seek medical attention immediately. These could be signs of a stroke, and early treatment is crucial. Maintaining a healthy lifestyle and managing risk factors can help prevent conditions like basilar artery thrombosis.
