Biopsy of the Temporal Artery
Biopsy of the Temporal Artery

A biopsy of the temporal artery is the definitive procedure for diagnosing temporal arteritis. Doppler ultrasonography is occasionally used to locate the part of the temporal artery to be biopsied. After a local anesthetic is injected, a shallow incision is made directly over the artery, and a segment of the artery at least 1 inch long is removed. The incision is then stitched up.
