PMD-TCD diagnosis of BA occlusion was confirmed in 11 of 12 patients who underwent invasive angiography. Reversed BA flow on PMD-TCD was identified in 8 patients (50%). Angiography confirmed flow from carotid system in 6 of these 8 patients (\u03ba=0.87). Patients with reversed BA flow showed lower NIHSS scores on admission (median 4 versus 15.5,\n            <jats:italic>P<\/jats:italic>\n            =0.009), on discharge (2 versus 21.5,\n            <jats:italic>P<\/jats:italic>\n            =0.03) and did not experience neurological deterioration during hospital stay (n=0 versus 4,\n            <jats:italic>P<\/jats:italic>\n            =0.05).
