Summary
Atlantoaxial dislocation can cause vertebral artery dissection and stroke, even in young adults without risk factors. This case highlights the importance of evaluating craniovertebral anomalies in young patients with vertebrobasilar strokes.
Area of Science:
- Neurology
- Vascular Surgery
- Radiology
Background:
- Craniovertebral anomalies are uncommon causes of vertebral artery dissection.
- Vertebrobasilar strokes necessitate thorough evaluation, especially in young individuals.
- Patients with stroke and no vascular risk factors require particular attention.
Observation:
- A 24-year-old male presented with posterior circulation infarcts.
- The patient exhibited no apparent vascular risk factors.
- Digital subtraction angiography revealed chronic dissection in both vertebral arteries with partial recanalization.
Findings:
- Computed tomography of the neck identified atlantoaxial dislocation.
- This is a rare instance where atlantoaxial dislocation led to bilateral vertebral artery dissection.
- The condition resulted in a stroke in a young patient.
Implications:
- Atlantoaxial dislocation should be considered in the differential diagnosis of young patients with vertebrobasilar stroke.
- Early diagnosis and management of craniovertebral anomalies are crucial for preventing severe neurological outcomes.
- This case underscores the need for comprehensive imaging in young stroke patients without traditional risk factors.

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended.

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...

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...

In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...

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.

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...
