Carotid dissection

Carotid dissection

Overview

Stroke is defined as a loss of brain function due to blocked blood circulation to the brain. Strokes may be caused by a narrowing, obstruction, or leak in the lining of the carotid. This leaking of blood into the artery wall (dissection) may cause a clot to form, reducing blood flow and raising the risk of a stroke. The leak may arise from an injury to the neck, which means stroke secondary to carotid dissection may occur in young people as well as older people.
