Temporal arteritis primarily affects which arteries?

Temporal arteritis, also known as giant cell arteritis, primarily affects the temporal arteries, which are located on the sides of the head. This condition involves inflammation of the arterial walls, particularly in the branches of the external carotid artery, with the temporal arteries being the most commonly affected. The inflammation can lead to symptoms such as headaches, scalp tenderness, and jaw claudication, and it is significant to identify and treat this condition timely to prevent complications, such as vision loss.

While coronary, carotid, and femoral arteries are important in various vascular conditions, they are not the primary focus in temporal arteritis. The involvement of the temporal arteries is critical because this condition can be a manifestation of systemic inflammation that involves the vascular structure in that specific region. Understanding that temporal arteritis distinctly impacts the temporal arteries helps in recognizing its clinical presentation and guiding appropriate interventions.
