Abstract:
Objective To evaluate the hemodynamics change of brain before and after vertebrobasilar angioplasty and stenting in the patients with intracal stenosis.Methods All the indexes were compared among thirty-eight patients with intracal arterial stenosis,including mean peak flow velocity,systolic peak flow velocity,and resistance index of hemodynamics ; Cerebral blood volume ( CBV),cerebral blood flow (CBF)and middle time to peak(MTT) before and after the operation.Results After vertebro-basilar angioplasty and stenting in the 38 patients,the Vs of PCA were significantly lower in the affected side [ (226 ±27)cm/s vs (135 ± 18)cm/s; t =21.74,P ＜0.01 ].Significant difference was found between pro-and post stenting of rMTT and rCBF in the blood territories of stenotic cerebrovascular ( t =3.987,P =0.001 )and( t =-2.027,P =0.029),There was no significant difference between pro-and post stenting of rCBV in the blood territories of stenotic cerebrovascular ( t =-0.901,P =0.329).Conclusions Transcranial Doppler and CT perfusion can be used to evaluate hemodynamic changes before and after pereutaneous transluminal angioplasty and stenting.
