Summary
Bilateral vertebral artery disease, a risk for stroke, was identified in a patient with neck pain. Conservative management with antiplatelet therapy proved effective for this rare case of vertebral artery dissection.
Area of Science:
- Neurology
- Vascular Medicine
- Radiology
Background:
- Bilateral vertebral artery disease poses a significant risk for posterior circulation stroke.
- Impaired collateral flow exacerbates this risk.
- Prompt diagnosis and management are crucial.
Purpose of the Study:
- To report a unique case of vertebral artery dissection with contralateral occlusion.
- To emphasize the diagnostic imaging features.
- To discuss conservative management strategies.
Main Methods:
- Computed tomography (CT) angiography for initial assessment.
- Magnetic resonance imaging (MRI) for detailed evaluation.
- Conservative treatment including antiplatelet therapy.
Main Results:
- A patient presented with neck pain and visual disturbances.
- CT angiography revealed left vertebral artery dissection with pseudoaneurysm and right vertebral artery occlusion.
- MRI confirmed no acute infarction, and symptoms resolved with conservative care.
Conclusions:
- Recognizing high-risk bilateral vertebral artery pathology is essential.
- Understanding imaging findings aids diagnosis.
- Substance abuse, like methamphetamine use, is a potential risk factor for arterial dissection.

01:10The Arch of Aorta
The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.

01:21Aneurysm II: Clinical Manifestations and Diagnostic Studies
Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
01:17Hemorrhagic Stroke l: Introduction
A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
01:26Arteries of the Head and Neck
The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

01:30Aneurysm I: Introduction
An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...
