Carotid artery dissection

Carotid artery dissection is a serious vascular condition where a tear forms in the layers of the carotid artery wall.

This artery is one of the major blood vessels responsible for delivering blood to the brain, and it is located on both sides of the neck.

When a dissection occurs, blood can enter the tear and separate the layers of the artery wall, forming a false lumen.

This can lead to the narrowing or complete occlusion of the artery, which may reduce blood flow to the brain and potentially result in a stroke.

Symptoms of carotid artery dissection can include sudden onset of headache, neck pain, and neurological symptoms such as vision changes, weakness, or difficulty speaking.

The risk factors for this condition include trauma to the neck, genetic predispositions, and certain connective tissue disorders.

Diagnosis is typically performed through imaging techniques such as ultrasound, CT angiography, or MRI, with the 'Head & Torso' and 'Whole Body' scans providing comprehensive views of the vascular structures involved.

Early detection and treatment are crucial to prevent serious complications, and management may involve medications to control blood pressure and anticoagulants to prevent clot formation.
