Transcranial doppler flow patterns. Sequential transcranial doppler (TCD) flow patterns are displayed. The left MCA is imaged via temporal bone window at a depth of approximately 5 cm. Panel a shows anterograde flow through the left MCA with the patient manually occluding the bypass graft (flow pattern above the line). The significance of the wave form is uncertain. Panel b display the retrograde flow pattern in the left MCA delivered through a patent EC-IC bypass graft (flow pattern below the line). In panel c is TCD done over the contralateral MCA showing a normal flow pattern
