    Cerebral blood flow velocity was measured by transcranial Doppler sonography at rest and during cerebral vasodilatation evoked with acetazolamide in 14 patients before and after carotid endarterectomy. Before surgery the vasoreactivity in the affected middle cerebral artery territories was reduced and abnormal (asymptomatic side: 35.9 +/- 25.6% [mean +/- SD; n = 14]; symptomatic side: 25.6 +/- 10.7%), but the difference between the two hemispheres was not significant however, vasoreactivity was normalized 5 days after surgery (asymptomatic side: 46.9 +/- 22.3% symptomatic side: 58.9 +/- 23%) (p < 0.001). The increase in cerebral reserve capacity and changes in Gosling's index of pulsatility correlated significantly in both hemispheres (p < 0.02). This findings indicate an improved perfusion reserve on the fifth day following carotid endarterectomy in patients with an internal carotid artery diameter reduction of at least 70%.
