Question:

Can you tell me the percentage of blockage I have?

Screening determined I have "significant" blockage on left side carotid.  Numbers shown are PSV:152cm/sEDV:53cm/s.  Does this equate to a percentage?

Answer:

by Texas Heart Institute cardiologist, Atasu K. Nayak, MD

Thanks for your question. According to carotid duplex USG [ultrasonography], you have 50-69% stenosis in the left internal carotid artery. Please consult a vascular medicine specialist and a neurologist for further investigation and treatment.
