Your ECA looks like it has a prolonged acceleration time, suggesting a significant proximal involvement.
I take it was accessed extra-cranially? Did you check the ICA and most importantly CCA?
As this a unilateral evaluation? If not- How did it compare side to side?

Subject: [External] 1st in my career today. Ran out of ideas

WARNING! External email.  Handle links and/or attachments with caution.  IS Service Desk @ 858-678-7500

I have done close to 500 temporal artery studies in my career and today was a first.....

Patient presents with intermittent vision loss and occasional jaw pain when eating.  Her ESR was mildly elevated at 35mm/hour and has occasional headaches.  All makes sense; however, here is when it became fun!!!!

ECA and early segments of the Common STA are essentially normal with antegrade flow and maybe a higher diastolic flow then normal but nothing crazy.  The Middle STA and both Parietal and Frontal ramus branches exhibit OSCILLATING flow with a retrograde Systolic component and an antegrade diastolic pull.  

She was a VERY hard study and the distal Common STA was not visualized.  My 1st thought was for some reason the Internal Maxillary was Stealing the blood; however to add another curveball, the flow in the Middle STA becomes more antegrade when I had patient exercise her jaw.

I am stumped!!!  Any thoughts?
