Bow Hunters Syndrome/Stroke-Rotational occlusion of vertebral artery
Is there a Neuro-Surgeon &/or Radiologist at MAYO who has seen/diagnosed/treated this condition? I found this:- Recommended procedure to confirm preliminary diagnosis "- Imaging B-mode transcranial color-coded duplex (TCCD), combines pulsed wave Doppler ultrasound with a cross-sectional view of the area of insonation.
- This allows identification of the arteries in relation to various anatomic locations.
- The color-coded Doppler also depicts the direction of the flow in relation to the probe (transducer) while recording blood flow velocities.
- In TCCD, the angle of insonation can be measured and used to correct the flow velocity measurement.
- A “Power Motion-Mode TCD (PMD/TCD)” will provide multi-gate flow information simultaneously in the power M-mode display.
