Occlusion and stenosis of left carotid artery
Clinical Classification Guidelines
Medical Intelligence & Overview
Occlusion and stenosis of the left carotid artery refer to conditions where the blood flow through this crucial artery is restricted or blocked. The carotid arteries are major blood vessels in the neck that supply blood to the brain, face, and neck. Stenosis indicates narrowing of the artery, while occlusion signifies a complete blockage. These conditions can significantly increase the risk of stroke and other cerebrovascular issues. Recognizing the causes, symptoms, and available treatments is vital for managing health and preventing severe complications.
