Abstract:
A totel of 120 patients with CT or MRI proved as acute cerebral infarction group of anterior circulation and 90 non-infarction patients as the control group were studied. The diameter,inter median thickness( IMT) ,peak systolic velocity ( PSV ) , end diastolic velocity ( EDV ) , early shrinkage acceleration time ( AT ) , resistance index ( RI) ,and pulsatility index( PI) of carotid artery,and whether there was arteriosclerotic plaque or stenosis,and the properties of plaque were examined with color Doppler ultrasound. In acute cerebral infarction group of anterior cir-culation,the IMT was thicker that in the control group(P<0. 01). The incidence of the film thickness,moderate-se-vere stenosis and instable carotid artery plaque in infaiction group of anterior circulation were obviousely higher than those in the control group(P<0. 01). Arterial complete or incomplete occlusion was observed in severe cases. The blood flow parameters showed that the PSV and EDV of common carotid and internal carotid in acute cerebral in-farction group of anterior circulation were lowerer than those in the control group. RI and PI of internal carotid in a-cute cerebral infarction group of anterior circulation were higher than those in the control group(P<0. 05),while AT was lower than those in the control group.
