Temporal Artery Biopsy
|Lines and access||
|Primary anesthetic considerations|
Shared workspace – the surgeon will be prepped and draped at roughly the ear
Be careful not to break sterile field when giving jaw thrust. Both arms likely tucked
Temporal artery biopsy is the primary modality to diagnose giant cell arteritis / temporal arteritis.
Giant cell arteritis is a chronic vasculitis affecting medium and large diameter arteries. It predominantly affects older individuals and will affect: aortic arch vessels and branches, and external carotid artery. The clinical manifestations result from inflammation of the affected arteries or from their gradual occlusion leading to signs of arterial ischemia.
Giant cell arteritis conformation
Incision is generally made overlying the superficial temporal artery at the previously chosen side and site (which can be found via doppler)
|Airway||Shared workspace with surgeon. Caution when giving jaw thrust|

Maintenance and surgical considerations
Caution when giving jaw thrust given close proximity to surgery.
