Objective To evaluate the value of transcranial Doppler to percutaneous transluminal angioplasty and stenting by compared with the hemodynamic change and digital subtraction angiography in intracal stenosis artery before and after the operation.Methods Fifty-eight patients with intracal arterial stenosis were compared all the indexes,including mean peak flow velocity,systolic peak flow velocity,end diastolic peak flow velocity,pulsatility index and resistance index of hemodynamics before and after the operation.Results Compared with preoperation,the indexes of mean peak flow velocity,systolic peak flow velocity and end diastolic peak flow velocity decreased in 51 cases while the pulsatility index increased,and resistance index had no change.All the cases were followed up with transcranial Doppler and digital subtraction angiography,and no restenosis occurred.The indexes of mean peak flow velocity,systolic peak flow velocity,end diastolic peak flow velocity,pulsatility index increased in 5 cases,no reflow signals were found.The indexes of mean peak flow velocity,systolic peak flow velocity increased while the end diastolic peak flow velocity reduced in 2 cases.The conformity rates which compared transcranial Doppler with digital subtraction angiography were higher in the moderate and severe stenosis,89% and 83% respectively.Conclusion Transcranial Doppler and digital subtraction angiography can be used to evaluate hemodynamic changes before and after percutaneous transluminal angioplasty and stenting.
