Dissection of the carotid artery occurs when the wall of the carotid artery becomes divided. Here, blood dissects between the layers of this blood vessel. It can begin in the neck and extend up into the brain. As the vessel wall is damaged, the lumen or opening in the artery through which blood passes, becomes narrowed or occluded. Portions of the brain may be deprived of their blood flow leading to strokes or death.
Causes of Carotid Dissection
Dissection of the carotid artery may develop from one or two principal reasons. First, trauma to the neck can tear the wall of the artery. This may propagate as the blood divides the wall of the artery. Secondly, athersclerosis may lead to degeneration of the arterial wall. This occasionally can lead to a defect where the blood pressure disrupts the wall.
Signs and Symptoms of Carotid Dissection
Pain may occur in the neck over the involved artery. If a stroke occurs, weakness, numbness' or difficulties with speech may develop. When the entire carotid artery becomes occluded a major stroke may lead to coma and death.
