Can anyone find 4 HPI?
Pt evaluated today for carotid stenosis. Seen at request of PCP. on eval, pt found to have a right cervical bruit. He underwent a carotid duplex US which showed a 16-49% cross-sectional area stenosis of bilateral internal carotid arteries. Bilaterally the degree of narrowing was closer to the 16% level. There is antegrade bilateral vertebral artery flow. There are no prior studies for comparison. The pt denies any history of TIA or prior CVA or amaurosis fugax.
